Hi there, I'm about to order a r tech MIG 180. It comes with the option of a 13a standard heavy duty plug or a 16a blue plug. I have a separate circuit in the garage for running 16a appliances but it only has standard sized 3 pin plugs. Do I get the blue plug and buy a conversion cable to run it in my 16a output? Or Do I get the 13a plug and run it via my 16a output?
