I've never needed to pull 220V off the TB until I got this XMT. I want to set it up so it can be running off the generator while I can be welding off the TB as well. As you may know, the receptacle is the 14-50 range style, for which already have two plugs.
1. Right-angle range plug.
2. K&H Industries P-1450DF plug.
I used K&H plugs and connectors to make up the 50' extension cord, and a K&H plug at the XMT pigtail. All of these are 6/4 SO cord, and I wired them up with all three of the current-carrying wires so I would be set for in-plant 3-phase.
My plan was to make a little 3' single-phase adapter cord to adapt to my shop and TB. So I test-fit a K&H plug to the receptacle on the welder, and unless I notch through the partitions between the work lug and the receptacle, and the 110V bank and the receptacle, the plug won't fit - it's way too big in diameter.
I hate to cut on the machine, but the main problem I have is I don't know how OSHA will look on notched partitions on the machine.
The little right-angle range plug I have is a tight fit, but I'm not sure it'll fit at all once there's a cord coming out of the bottom, again because of the way the receptacle is recessed into the TB. I'm also not sure I can stuff (3) 6-gauge wires into it, as compact as it is. Especially for the ground lug.
The only other option I see is that Cooper/Arrow Hart makes a straight plug, part number 5745N. Has anybody physically plugged that plug into a TB302 receptacle? Does it fit?
If not, what do you do to use your 220V receptacle?
