Multi-purpose welding cart

[Todd Harrison] put together a welding cart that has all kinds of tricks built-in. The carcass is a cheap rolling cart that has been reinforced with steel plate and beefier wheels. The top tray can be loaded up with fire brick for oxygen-acetylene welding or with a grate for cutting. That grate lets the slag fall through and into the red-rimmed fire-box below. Finally, there’s a steel plate to the right of the cart that rotates and slides over the top of the unit to prepare it for MIG welding. Todd walks us through his versatile invention in the video after the break. This will nicely augment your other welding hacks.

Flux-cored to MIG welder conversion

[Rob] sent us some information on how he converted his flux-cored welder to a metal inert gas welder. He used a piece of DOM tubing as a collet with a side inlet tube that he uses to inject carbon dioxide. The gas is sourced from a 12 ounce paint ball CO2 tank and it looks like there’s a valve right at the junction with the collet. We wonder how long it would take to tear through one of those tanks, but if you’re not doing a lot of MIG welding this saves on the upfront cost of buying a separate setup.
