Smiley Plasma/Tig - Ground or Neutral?
 

I got the 30a smiley unit, and it has 3 wires (2 hot, with "ground") and a ground on the case in the back. Shouldn't the "ground" wire be neutral?

Re: Smiley Plasma/Tig - Ground or Neutral?
 

Just hook of the 3 wires and your good to go.

fair enough, so 2 110v and a ground

Re: Smiley Plasma/Tig - Ground or Neutral?
 

Yes.

Re: Smiley Plasma/Tig - Ground or Neutral?
 

nvm

Re: Smiley Plasma/Tig - Ground or Neutral?
 

man!

spent half of the day wiring it up (did not have 220v), getting the compressor, hooking it up, and realized they forgot to include the ground clamp!!! ugh!

p.s. how the heck would you hook up argon to the connection in the back? with the nylon hose? Just plain air seems ghetto rigged as is.

p.s.s is the air regulator supposed to "leak" out of the valve or whatever it is on the other side of the gauge?

p.s.s.s should the breaker be 20 amp or 30 amp? (highest input current according to the chart is 19amp)

Re: Smiley Plasma/Tig - Ground or Neutral?
 

Yes Argon goes to the same input as the air. I rigged up a quick connect system so it only takes me 2 seconds to switch.

Argon get connected with a Hose and Hose Clamp.

As for the 20 or 30. Might be fine on the 20 amp, but I know mine is on a 30.

how did you do the quick connect thing?

Re: Smiley Plasma/Tig - Ground or Neutral?
 

I used some gas quick connects, like the one for oxy-acetelene torches. For a while I used just reqular air line fittings.
