ah okay, i was just wondering and i didnt know if TIG machines are made to be specifically one way ie, DCEN or DCEP. i didnt know you can alternate between them even though it has + and - marks on the machine.

hmm i understand, i will try and see if anyone has got one of these. i have one more question.

those chinese welders are DCEP, it shows the torch as + and workplace as - on the machine, will it be possible to reverse the polarity? will it damage the machine? or does it not matter

no help from anyone?

Hello guys i just registered here so i am new and i am a total beginner. in fact ive only used MIG once, and no experience with TIG at all. now i know what some of you may say... that its too dangerous or not worth trying, but i am currently in the middle of a project and i need to weld some 3mm alu...
