I tough for a while test on a cane toad that right now are quite abundant at my place
) . If all 3 in 1 works like that or only mine ?

In addition to a hi voltage start, the standard setting for TIG welding steel is with the torch being negative.
IN such case the High Voltage shouldn't be activated when you do press button on the TIG gun only?
I did try to MIG welding on the TIG mode setup but looks like unit is overheating after several seconds, so I could weld a 1 cm at the time.
Same with MMA , but the start with stick is at least much easier and sound comming out of the spark brilliant.
As you said I thought that flipping the TIG switches may alternate the polarization on the MIG gun, but so far I have no means to check it out.
There is huge relay inside the box that may do just that, but I could not scarify my 4th multimeter.
inside Inverter TIG, MIG MMA welder
big relay
Macroscien, how many (big) terminals are going into that relay? If there are only two then it won't be changing the polarity.
It is very unlikely that they would change the polarity this way. It is easier for them to just swap the leads on the front panel.
The manufacturer might have gotten cheap and left the HV start on everything. It shouldn't matter, but I can only see the real benefit of having it with TIG.
Macro, to change polarity you need an H-bridge circuit. So a double-pole double-throw relay (6 terminals) could technically do it, but is considered a ugly solution, because it can go through a temporary shortcircuit on either side of the H while switching... Can you describe the relay connections?
Re multimiters: buy Fluke, not the stuff on the photos.
Dont bother ever trying to TIG galv even after grinding as porosity will jump straight to your tunsten tip and that is the end of that, MIG is the best option as you can weld quicker with less contamination.
Lend him yours if you think they are that good.

Dont get to intimidated by a 10amp mig/tig mac. cold starts etc :40 amp 3phase.The machine you have very valuable is good but from a professional level very limited.There is a setting for Coldstarts on 3 phase Tig welders start arc craterfill etc.
Unless you want to spend 5 grand and use 3phase dont stress about your welder !
Dude your not welding pressure vessels or require xray quality !! For general fabrication it will do fine.
