Trolley for semi-automatic welding machine: design features and drawings – Consumables and components on Svarka.guru

A medium-power semi-automatic welding machine itself weighs a lot. In addition, a cylinder with protective gas, a hose, a torch, wires, and a mask must be delivered to the welding site. The tool for preparing the welding zone, cleaning seams, a supply of welding wire, and other consumables also takes up space and weighs a lot. A semi-automatic cart is useful for this. Everything you need for work is conveniently placed on it. Such products are mass-produced and have two, three or four wheels. Experienced craftsmen are not satisfied with industrial designs; they design and independently make carts “for themselves.”

Characteristics

The purpose of such equipment is to ensure the mobility and convenience of the welder, to reduce the loss of time preparing for welding, dragging tens of kilograms of equipment, tools, and materials. With the help of a trolley, a full-fledged mobile welding station is created, which contains everything that is needed to perform a weld anywhere in a workshop, workshop or construction site.

The main characteristics of such trolleys are as follows:

Load capacity . The structure must support the weight of the welding machine, cylinder, hose, wires, consumables, and auxiliary tools. The total easily adds up to a hundredweight, or even more.
Sustainability . The design of the trolley must prevent it from tipping over, even if a passing assistant touches it or the welder pulls strongly on the hose.
Capacity . In addition to the welding machine and gas cylinder, a large number of large and small-sized items need to be placed in convenient trays, boxes or hangers. They should not wobble or fall out while moving.
Dimensions and maneuverability . A trolley for a semi-automatic welding machine with a cylinder should take up little space, the dimensions of the vehicle should allow it to pass through passages up to 70 cm and turn almost at a right angle.

In addition, the device should have easy movement and a comfortable handle.

Do-it-yourself trolley for a welding machine according to drawings

You can make a cart for a semi-automatic machine yourself. To do this, you will need to prepare a number of tools, study drawings and a step-by-step manufacturing plan. The first step is to find a drawing according to which the homemade product will be made. It is worth analyzing the manufacturing process, starting from a specific example and drawing. This will help you more accurately and efficiently consider the process of assembling a cart for a semi-automatic machine with your own hands.

Necessary materials

The first thing to start with is preparing the materials. What you will need to assemble the structure:

Reference! At this stage, the user can either immediately visit a specialized shopping center or store, or look for all the necessary elements in his garage.

profile pipe;
fittings;
reliable wheels;
long bolts with nuts;
corrugated sheet aluminum;
two wheels from carts;
welding machine;
pipe bending machine;
vice;
Bulgarian;
drill;
roulette;
marker.

It is very important that the materials meet the above requirements.

Technical data

Manufacturers market several basic types of welding trolleys. Their main dimensions are determined by the dimensions of the welding machine and gas cylinder.

Typical parameters look like this:

weight: 12-15 kg;
overall dimensions: 1.25x0.35x0.71 m
size of the platform for the device: 0.28x.45 m.

These parameters are specified based on the capacity and number of cylinders with which the mobile post needs to be equipped, as well as the selected layout.

The most popular are two of them:

two-wheeled layout , a large-capacity cylinder is placed vertically, the platform for the device is located above the axis and parallel to it;
three- or four-wheeled layout , dimensions are determined by the dimensions of the platform for the welder, cylinders of small or medium capacity are placed under the platform.

Two-wheeled options are created on the basis of a standard trolley for transporting 40- and 50-liter gas cylinders; a bracket holding the platform for the device is welded onto their vertical handle

Three- and four-wheeled models are created on the basis of mobile tool cabinets, to which cylinder mounts are added on the side or bottom.

To increase convenience and improve the working conditions of the welder, the cart is equipped with compartments for storing small tools, reels for winding and storing hoses and wires, etc.

Types of carts for carbon dioxide, oxygen and propane

Cylinders for different gases and purposes vary noticeably in size, so they require different carts. As you can see, they also make designs for oxygen plus propane pairs.

The most popular designs are for one cylinder. In this case, the wheels can be placed at the bottom or at the center of gravity of the cylinder. In the second case, the load is quite high and the structure is unstable, but the load on a person in this case is the least.

In some cases, it is convenient to use a combined welding cart for gas and semi-automatic. Then you need to add two more small wheels under the welding table.

Another option is a mobile device for moving cylinders. Such a cart can be rolled indoors, carried manually by two people, or rolled on wheels into the trunk of a car. It is this device that we will consider first.

Technological components

For the manufacture of trolleys, a metal profile of round or rectangular cross-section is used. For the platform, steel sheets, expanded metal mesh or a transverse set of corners are used. The blanks are welded together, then cleaned and painted with powder paints to protect the structural elements from corrosion.

If the device is used in enclosed spaces with a flat floor, cast wheels of small diameter are usually used. If you plan to go outside, choose pneumatic rollers with a larger diameter that can handle potholes and other obstacles.

The trolley must be equipped with a device that prevents its independent movement. For two-wheelers, this is a heel support; for three- or four-wheelers, wheels with a built-in pressure brake are used.

Additional requirements

Depending on the characteristics of the technological process that will be provided using the trolley, additional requirements for its design may be put forward, for example:

additional shelf for placing a water cooling device;
additional places for cylinders;
hangers for replaceable burners;
waterproof cups for storing rod electrodes;
oil and acid resistant wheels.

For outdoor use, a casing can be added to protect the equipment from the elements.

Execution options

There are many options for the design of trolleys for semi-automatic welding machines.

Some of them are designed to transport only the apparatus, but more popular models are those that simultaneously transport a gas cylinder or cylinders, and all other items necessary for welding.

Two-wheeled options, made on the basis of a trolley for transporting cylinders, are distinguished by the greatest load capacity and maneuverability ; thanks to the large volume of gas cylinders, they provide greater autonomy. They are also distinguished by greater maneuverability and maneuverability.

Three- and four-wheeled models can only move on a flat floor or asphalt; even a 10-centimeter bump or high step can become an insurmountable obstacle for them. To increase maneuverability, the front wheel (or wheels) are made swivel. The main advantage of such structures is their high stability, ease of operation and access to contents.

wow, what a bourgeois))) You’ll find 20 liter horseradish cylinders, and if you find them, they refuse to fill them up - they say just overfill them. I also want a small one like this, but apparently it’s not fate. Tomorrow I’ll start making a cart for 40 liters, but 20 should also fit

I literally changed this cylinder to a 40 liter one a month ago. This one was 25 liters, besides, I turned off the valve on it) They took it away, and with an additional payment I took a 40 liter cylinder for myself. Now

I just wanted a small size. but there are only 10 and 40.

10 seems to me to be about nothing at all.

Well, if you go on trips, then nothing. In the meantime, I’ll be training, I’ll blow away this ten in a month

It depends on how much you cook on the road, if you sneeze and puff and that’s it, then it’s easier to take flux-cored wire. And if from the pick-up until dinner, then 10 km is not enough.

argon-arc. And so as not to carry a semi-automatic device, you can use piece electrodes. they are cheaper too

Greetings! Tell me about the cylinder. How many liters and how long does it last for heavy work?

Hello. The volume seems to be 30 liters, I have never refilled it yet.

Another question...what should be the pressure on the gearbox for a quality weld? At the moment I’m just working with flux-cored wire. It’s expensive. I want to buy a carbon dioxide cylinder

Yes, I somehow feel it, it should hiss slightly when you bring it to your cheek))

Thank you. One fine day the gearbox simply stopped letting carbon dioxide pass through -) I haven’t taken it apart yet, so I installed another one.

Yes, it seems not, you can open the lid and change it.

Honestly, since I bought a large reel, I haven’t changed it even once, though it seems to be on the way. I don’t cook on an industrial scale...

Before this there was none)))

Good execution, the main thing is that it is convenient and comfortable for you to work with. I also welded a cart for my Overman 200, maybe I’ll post it here later.

Hello, Now I’m also making a cart, and also for an overman. There were questions about the wheels. What kind of wheels did you get from Leroy? Does the cart ride on the ground (grass) with front swivel wheels? How did you attach the wheels themselves, what was used as an axle?

Hello. I took inflatable wheels from Leroy. It rides fine on hard ground, I haven’t driven it on grass, but I think it won’t be very good. I wrote that it would be nice if all 4 wheels were inflatable, but I didn’t want to mess with the turning mechanism.

How did you attach the wheels to the axle?

I welded a long bolt from the bottom of the cart, welded a washer onto it, put on the wheel, a second washer and a cotter pin.

Heh, another question about the wheels, what size are your front wheels? I found 200 mm in the store - rotary. Will there be a forward tilt? Thank you.

Yes, also in this size, I think. You need to look at the slope locally. The swivel wheel also has a turning mechanism, which also adds height.

If it's not too much trouble, can you tell me the dimensions in a personal message?

I have the same machine, I’m just learning how to cook p/a, I wanted to make a cart. Can you give me a drawing or dimensions? I want to calculate how much metal I need to buy.

Of course, there are no drawings. I did everything locally. I can measure it when I’m in the garage, I don’t plan to in the next few days. I'll be there, try it on and write then.

It turned out great. I will also do the same for my Aurora)) How to change the wire, does the lid open up?

You don’t have to change the wire every day, at least for me, in extreme cases you can pull out the device, but you can safely open and replace it anyway.

Greetings. A little off-topic question. Please tell me, how do you like the Overman 180 welder? Can I get one for my home and my crafts?

I love it! I read a lot of reviews, but I haven’t heard anything bad about this device!

I also read the reviews, but I decided to ask a real person who uses it)) Thank you.

Features of two-wheel design

The platform supporting the cylinder from below is made in such a way that it turns into a stand and support for the entire structure when the cylinder is placed vertically. It also acts as a reliable brake.

The two-wheeled trolley for transporting semi-automatic weapons has two positions -

working, when the base is on the ground;
transport, when the cylinder is tilted, the base is lifted off the ground, the structure can roll on wheels.

A bracket for attaching a semi-automatic machine is hung on the frame in a convenient place. The bracket for the semi-automatic machine is welded to the handle. Since the trolley tilts at an angle of up to 45° during transportation, the device is secured to the bracket with straps

Additional brackets for boxes with tools and equipment, hangers for coiled wires and other parts are welded to the handle.

Three-wheeled model

A three-wheeled trolley for a semi-automatic machine with a cylinder mount is much more convenient to use than a two-wheeled one . Free access to the device, other equipment and welding materials is provided; they do not need to be secured during transportation.

Its capacity is significantly higher than that of the two-wheeled version. It is possible to install drawers, additional shelves, cabinets, removable containers and much more.

Three-wheeled design drawing

With such a device you can transport everything you need for work to the far corner of the workshop and not have to return for every little thing you need. The convenient handle allows you to both pull the device behind you and push it forward. Swivel wheels provide sufficient maneuverability.

Again my perfectionism got the better of me and, turning a blind eye to the price, I decided to buy this

The price of this sheet in OBI is 1499 rubles o_O And I attached it to the bottom of the cart like this

I also bought a yellow sling and wrapped it around both crossbars, making the upper one in the middle part soft with the help of round pipe insulation (the gray one) it will become clear later why. The assembled cart looks like this

I used rubber spare tire mounting straps from a VAZ 2101 as clamps to hold the cylinder.

According to the master plan, the cart is not only for moving the cylinder around the garage but also for transportation in the car. I roll the cart up to the trunk and tilt it, resting it on the rear bumper with that same soft cross member that I mentioned above.

To hold the cart in a transverse position, I used a chain and two lanyards.

I haven’t found two studs to secure the wheels yet, but I’ll definitely do it! there is no need to write about this in the comments again))) We also welded two ears for which I will attach the “collar” to the cylinder.

Overall, I'm very pleased with the cart. I have already moved the cylinder to a better place in the garage. It was not difficult to load this entire structure as I wanted. I also discovered a “side effect” of the cart, which is that now it will be much more convenient to carry the cylinder even if two people hold the cart by the longitudinal pipes in the middle. Thank you for your attention.
