Just got my Cut50D and am trying to use it. I am currently hooked up to 110volts because Lowe's doesn't seem to carry welding plugs anymore so I can't plug into my welding receptacle. I have the air pressure set to 70psi on the front gauge, I have the blue wire on the neutral, green to ground terminal, and brown to hot. I've tried adjusting the amperage to yield a different result as well as using brand-new metal vs. rusty metal.
Here's what happens: I put the torch close to the metal and nothing happens, but once it is almost touching and touching I see very faint blue sparks around the copper electrode. Thought it might be a bad ground so wiggled it around but still won't cut. I went ahead as a last ditch effort and put the torch to a spot on the ground clamp and it tired to blast for a second and actually made a tiny mark, but that's as good as it gets. What do I do?
