Well. My range runs on 240v and it's the right next to where I'm going to weld. I'm just not a big fan of moving it everytime I want to weld but if the general concensus is that I need it rather than 120v then there's no other option. I wired in the 20amp line for a 1 ton AC unit on the otherside of the house and cost me 100 CAD to do it. Problem is I have no more space in the box for another line. So adding another line would mean breaking out to another box and the cost will skyrocket from there.

Getting creative, I wonder if I can just add another outlet to my range circuit and weld off that. I know, 2 appliances on 1 240v line is not recommended. Any electricians here?
