All I have right now is an electric drier outlet thatís not the same plug configuration needed for the MM180. So I bought a 6í 10gauge 30 amp drier cord for a pig tail, connected the power outlet (wall receptacle) to it that the welding shop told me to use, My question is: is this all I need, to then plug in the 25í 8/3 extension cord for my MM180 ? The MM180 cord is 12/3
Will this be safe to use..

Thanks
