I have one of those small Campbellhausfeld stick welders. The instructions say to use a 20amp outlet when welding with 5/64" rods and the high setting. My garage has 15 amp outlets even though the wire is 12 gauge and the circuits are on 20 amp switches. So what is going to happen if I run it on high and use 5/64" rods on one of these 15 amp outlet? Am I only going to get 15 amps and poor performance? Or am I going to ruin the welder? Or burn my house down? If I put a 20amp outlet on the wall will it make it possible to use 3/32" rods? They are far more common than 5/64".
