I have to disagree with Ady on the need for 200+ amps for easy stick welding ! The open circuit voltage could be said to make life easier rather than huge amps. I have one very similar to this which is fine for small work, another inverter unit that is 175A I use for bigger stuff. 2 oil cooleds at 110A and 180A, 2 MIGs at 160A and 180A and a 3 phase MIG at 375A, though this last one will go down to doing car body repairs, as well as blow the edge off a 1/2″ girder if you wish !

SIZE may matter but knowing what to do with it is better, also being able to weld properly is important

At that price if it gets you out of a hole then money well spent ! The construction may not be great but a few simple mods like good connections to be able to take the current or beefing up tracks with solder are worth the effort. Note that the duty cycle is only 40% !

If you want to use it on TIG you will need Gas, a regulator, and a TIG torch kit. This will cost more than the welder. It will be scratch start.   Noel.

Proper tig welders are actually quite advanced and have extra knobs for varying the voltage, pulse duration etc

A decent tig machine can probbly be used as a very good stick welder, and prduce a better more stable arc etc

Most of the inverter welders have the TIG ability so you just have to buy the extra TIG torch etc. my machine Mart one certainly does.

I don’t think I have even used it at full power as the stuff I weld tend to be reasonably thin and having 200plus amps would just melt right through the work. Lower amps also means you can simply plug into a household 13amp socket
