How welding cart sizing works
Welder + extras rule, 265/350/400 ladder, and cylinder safety.
Welding cart sizing
Welding cart capacity calculator
Enter welder/plasma weight and tank, cables, and tools on the cart in lb. Get required capacity (welder + extras), then a 265 / 350 / 400 lb class — or NO_MATCH. Confirm static vs dynamic rating; chain cylinders; never exceed nameplate; not a lifting device.
Welding cart sizing
Result
Required = welder_lb + extras_lb. Classes: 265 · 350 · 400 lb. Above 400 lb required → NO_MATCH. Confirm static vs dynamic rating on the listing; secure gas cylinders with chains; never exceed nameplate; a welding cart is not a lifting device.
