Hi,
I'm an amateur who owns a Titanium 225 stick welder. It works well for me. It can operate on 240 volts or 120 volt: there is a switch you have to flip into the correct setting.
Most of the time I use it on 240, but occasionally I used it on 120. What if I forget to flip the switch? In either direction. I'm afraid I'll do that once and I burn up the welder.
Thanks!

240 on 120V does nothing, the machine probably wont even start.
120 on 240V pops a fuse (if the machine has one) or damages the transformer coil. However if your machine has a switch, that usually means it has a protection circuit meaning that 120 on 240 wont do anything since the machine wont even turn on (however read the manual just to be sure).
Haha, I did check the manual, and it just said to switch it to the correct voltage.
Ok so it has a circuitry to protect itself.
Maybe, but it doesn't say that. :) No word on consequences. Unless I take the "failure to follow these instructions can cause bla-blah" clause as that.
“You feelin’ lucky, punk?”
I've got the same welder and it came with the adapter plug and the switch will light up which voltage it is detected & wont arc til its flipped to that voltage. I have really abused it and run it off generator 220 plug most of the time with an adapter that I made and this thing has give me no problems I would definitely buy another one if mine ever quits from being left out in the rain for the 100th time. The best $300 I've ever spent on any welder. My old tombstone just sits in the corner collecting dust
I agree, it's a great welder. The stinger broke the second time I used it (the actual copper/brass holder), but after I replaced it, no more issues.
Shouldn’t it have different plugs for different voltages?
Cheap dual voltage inverters typically have a single nema 5-20 plug and come with an adapter to 6-50.
Yeah it's like that, just the other way around. 6-50 is the default plug.
It woould be be nice if it could detect the plug or the voltage.
My Vulcan Protig does that, just flip the switch and it figures out how many angry pixies it has to work with.
My IGBT tig/stick machine figures it out and works plugged into whatever.
If it is set to 240 and you plug it into 120 it will likely just not work until you flip the switch to 240. The other way around may cause catastrophic damage. I would probably put a tag at the end of the cord that says check voltage input to remember.
