Came across this on sale for just $230. Runs a standard 10 amp plug so no need to call in electrician to fit 15 amp outlet (cheapest quote $250).

Would this be suitable for cold rolled and zincanneal sheet 1.0 - 1.2mm gas mode? The lowest setting appears to be 38 amps according to the specifications.

The other option I was looking at was a unit that can do mig and tig suitable for carbon steel sheet. What lower amperage would be required for tig?
Some units go down to 5amp whilst others are 40amp. The one I was considering was something like this:

However considering the unit price and electrician for 15amp plug it would have to be a good setup for welding carbon sheet.
