I Have a Harbor Freight 230V 120A MIG/Flux Welder, with no plug for it (Manual says it draws 21amp max). It has 3 wires coming out of the power cord for a 3 prong plug. I have a spare dryer outlet in my garage, although it is the 'new' 4 prong connection.
I was wondering what plug I need to buy for the Welder, and if there is anyway I can plug it into my Dryer outlet, to avoid having to run another outlet.
Since I will be needed an extension cord of course, this is prob a stupid question, but is there a extension cord that goes from a 4prong to a 3 prong?
Any help will be much appreciated, thanks
