Hi,
With Gas-Less MIG welders you tend to struggle welding very thin sheet as they don't burn as smooth as a standard Gas type MIG, having a stronger, more unstable arc which causes burn through on very thin metal.
With your machine only having two settings you can't fine tune the arc & it's a case of all (high) or nothing (low). The minimum setting on low on your machine (63 amps) is also way too high - 30amps is typical on most machines which is half yours.
Its the same as this welder, http://www.valleymetal.org/MIG Welding/index.htm I doubt its just all or nothing from looking at it there is a 1 and 2 and min and max setting. So it seems similar to the 90 amp welders with the only difference being that it goes from 25-87 rather then 63-90 amps
Well its not exactly the same, the one Im looking at is made by chicago electric but it does have the same adjustments, etc. Also what would I need to convert to gas? And what gas and wire and pipe would you suggest?That's manufactured by Cemont in Italy. Does appear as though it has variable power output and goes down to 25amps, so will be fine for what you need.

For SS you want Argon/Co2 (short circuit mode), Argon/O2 (Spray arc) or trimix (Argoshield, short-circuit mode) .Ah well, if it's stainless another reason you must have gas. Pure argon is the stuff to use & 308 grade wire (for 304 grade tube).

Must have been you thinking "you really want TIG for the best welds" and the pain from biting your tongue.You are quite correct Shenion, DOH! I must have been thinking TIG. It's late here in the UK (1.30am) so I think I should go to bed after that one
