Converting Dynasty Receptacle from 4-prong to 3-prong

[erikmannie]

Perhaps most interesting of all, when I was futzing with the stock 4 cable (8 AWG?) SOOW cable coming out of the Dynasty (on the machine end, my Dad wanted to test continuity at the other end of the wires), I noticed that my freakin’ water cooler wasn’t plugged in!

The 110V plug had come unplugged at some point, and I burned up my well-used CK Worldwide TIG torch, posting a whole thread about this issue here on the forum… without checking first to see if the water cooler was plugged in! This is why I can’t have nice things.

I guess I will make it a habit to check that the water cooler is plugged in before I TIG weld. It should be noted that I usually use this machine for stick welding, as it runs 6010 beautifully.

As promised, here are some self-explanatory pictures of the action.

Here are the last 3 pictures of the action, using the term “action” loosely.

You didn't have to tape the other red wire. Since it is red, it is understood to be a "LINE" wire and both LINE wires are interchangeable.

The wiring also needs to be 50 amp capable, not just 40 and come from a 50 amp breaker.

Great info!

I think the wires coming from the panel are 6 AWG.

I do know that the two LINEs are interchangeable on A/C.

My Dad was the one who helped me with the “circuit breaker to welding outlet” wiring a few years ago. We only had red wire on hand; at that time, I knew next to nothing about home electrical.
