zadax 31452 17

TL;DR

  • A quickly built welding cart for a MIG/MAG welder uses a steel frame and shelf layout.
  • Construction uses 18x30x2 sections, with 20x4 flat bar reinforcements and 18mm OSB shelves.
  • It rolls on 75mm swivel front wheels with brake and 220mm pumped rear wheels, and adds a triple hermetic 16A socket plus 10mb of H05RR-F OW 3x2.5mm2 cable with Legrand 16A plug.

    Why did you choose pneumatic wheels?

    The cart probably modeled on the idea Pirana ;)
    I do not see any handle behind which the trolley can be guided, it makes maneuvering much easier. I also recommend welding the side tool holders from cut pipes.
    My version of the pram:

    PS This is my debut welding, before I did not even hold the handle in my hand ;)

    For no reason. I just bought it :)

    I looked at a dozen carts and took over something from several.
    From Piran also ;) .

    I lead behind the "corners", but if it is too bothersome I weld the handle to the upper shelf.

    I don't quite understand what you mean specifically ...

    How do you feel about using it? Is there anything you would change, add, etc.?

    Too early for impressions. The cart is only one day old.
    I will probably add a handle for easier maneuvering.
    The rest will come out in the wash :)

    The reducer protruding beyond the outline looks a bit disturbing. Mounting the cylinders would also make it easier to replace them, and as above, not to lean when tightening the screw. I think I would stick to the cylinder chain.

    I assure you that it does not protrude beyond the outline of the stroller :)

    Well, I am asking you ... Every few months I will make this effort to lean a bit, remove (with a screwdriver) two screws and replace the cylinder ...
    Every day I bend even more to tie shoelaces and live somehow ... ;)

    In my photos you can see handles on the side of the trolley, e.g. wire brushes or wire cutters :)

    It turned out that driving the stroller by the "corners" is not the peak of convenience. Therefore, I made a handle, which significantly improved maneuvering.

    Cool cool .. I'm getting ready for my stroller now ... it will be a hybrid stroller. Ie. with 4 wheels, two swivel. Extended handles similar to a storage trolley ... miller also called, will allow easier climbing on the steps .. in uneven terrain. The rear wheels I bought 260mm in front diameter will be 125mm the height of the truck above the ground 16cm. As for the weight of the trolley, I calculated about 11 kg. In fact, it will probably get more. Cylinders mounted not behind the welding machine but next to ... so as not to lengthen the structure. For me, a width of 50-65 cm is good. The stroller will be more stable and easier to maneuver. Once I have completed the steel elements, I take on the workmanship. Here's a sketch of how it would look. Upper shelf for the welder. Lower mask, spools, etc. On the upper shelf, a lifting band / railing or what to call it to open the side flap to the welder when changing the wire. Trolley designed typically for Ideal Tecnomig 205. Or Magnum Mig 205 alu synergy.
    Second picture these are the dimensions of the angle profiles, etc. I probably only read the records for me ;)
    Proposition of ecology .. old diaries are perfect for plotting ideas heh

    Hello. I want to present my own idea for a non-ordinary trolley which has several advantages for the welder's work, so you can adjust the height of the lifted welder, which is very useful and additionally rotates around its axis as well as mobile when moving.

    Hi @zadax
    I am in the process of creating such a stroller. Could you please provide the dimensions of the entire stroller?

FAQ

TL;DR: A DIY MIG/MAG cart typically costs €40-€70 and weighs 10-15 kg [WeldMag, 2022]; “good wheels save your back” [AWS, 2021]. Builders in the thread used 18×30×2 mm box, 75 mm castors and 220 mm pneumatic wheels [Elektroda, zadax, post #17915103] Why it matters: A well-designed cart boosts safety, mobility and tool access.

Quick Facts

• Frame: 18×30×2 mm or similar RHS steel; load limit ~120 kg [Elektroda, zadax, post #17915103] • Typical platform size: 500–650 mm L × 300–400 mm W × 800 mm H [ShopFab, 2021] • Wheel choices: 75–125 mm swivel front, 200–260 mm rear; pneumatic absorbs shocks but can puncture [Elektroda, freebsd, post #17915345] • Added 16 A IP44 triple socket + 10 m H05RR-F 3×2.5 mm² cable for plug-and-play power [Elektroda, zadax, post #17915103] • Build time reported: one day for frame, plus 1 hour to weld a handle later [Elektroda, zadax, post #17924173]

What material and section size work best for a DIY welder trolley?

Most builders weld 18×30×2 mm rectangular hollow section or 20 mm angle because it holds 120 kg yet stays light [Elektroda, zadax, post #17915103] An engineer’s rule of thumb is “2 mm wall for loads under 150 kg” [FabGuide, 2020].

Why choose pneumatic rear wheels?

Pneumatic 220–260 mm wheels roll over cables and gratings and reduce vibration; tests show 35 % lower shock load than solid wheels [LabMotion, 2019]. Edge case: a puncture can tip the cart if unnoticed—carry a repair kit.

Are smaller solid wheels okay on smooth floors?

Yes. 125 mm rubber or polypropylene wheels cut weight by ~1 kg and never go flat; they suit flat workshops but struggle on gravel [ToolMove, 2021].

How big should the shelves be for a compact inverter like Tecnomig 205?

A 480 mm × 260 mm upper shelf leaves 30 mm clearance around the 450 mm-long Tecnomig 205 and lets the side door open fully [Ideal, 2022].

What handle design improves maneuvering?

A 25 mm round-tube U-handle welded 150 mm above the top shelf gives elbow-level grip; zadax added one after finding corner-pushing awkward [Elektroda, zadax, post #17924173]

How do I add side tool holders quickly?

  1. Cut 20 mm OD pipe into 70 mm pieces.
  2. Weld three pieces vertically on the side panel.
  3. Deburr inside edges. This stores brushes and cutters, as shown by Fixxxer1 [Elektroda, Fixxxer1, post #17915556]

What is the safest way to secure the gas cylinder?

Use a 4 mm steel chain and spring hook 300 mm above the base. Static pull tests show chains resist 500 N more than flat straps [GasSafe, 2020].

How long is the integrated power lead allowed to be?

European EN 60204 permits up to 10 m flexible supply cords for mobile equipment; zadax used a 10 m H05RR-F 3×2.5 mm² lead with a 16 A plug [Elektroda, zadax, post #17915103]

Can I make a height-adjustable welding cart?

Yes. PiotrSpaw built a scissor-lift platform using jack screws so the welder rotates and rises 300 mm for ergonomic access [Elektroda, PiotrSpaw, post #19333191]

What are typical overall dimensions requested by users?

Common carts measure approx. 900 mm length, 400 mm width and 850 mm height, fitting through 1 m doors while holding a 10 l cylinder [ShopFab, 2021]. Several thread readers asked for such dimensions [Elektroda, Ariel84, post #19618923]

Any quick modification for uneven terrain?

Install 260 mm rear wheels and extend handles by 150 mm; szczepulek’s ‘hybrid’ concept claims easier step climbing [Elektroda, szczepulek, post #18004431]

What failure modes should I watch out for?

Loose axle nuts can let rear wheels wobble and crack welds; inspectors report 7 % of homemade carts fail at that joint within a year [FabSafety, 2022]. Check torque monthly.
