One of the guys here at work upgraded his MIG welder to one with spool gun
capablilties. He offered me his old one at a price I couldn't refuse. It works
really well, but the leads were short, and I didn't have a 20amp outlet for 
it, which limited me to the lower settings for heat. I installed a 20amp plug
near the panel in my shop, but I wanted the ability to weld anywhere in the 
shop, and maybe the driveway. So I bought 9 meters of real 12 gauge extension
wire and hardwired it into the welder. I then bought 10 feet of #2 welding 
cable and replaced the ground lead with that. 

 The welder worked really well, but was low to the ground, which meant the short
torch cable was bent into a sharp 'S' shape when I was working on the bench. 
This made the wire feed unpredictable, and made welding trickier.So I decided to
build a cart for it, which would have the extra bonus of giving me a spot to store
the longer cables, as well as allowing me to work at a higher position.

 MigCart* files show the assembly and final product. I got to use my new JD2 tubing
 bender for the side rails. It works well, but I need more practice to make my bends
 where they should be!
