New tool in the shop arsenal...

Is there a 110/220 switch on it, or is all you have to do plug in the adapter?.... :o

No switch, so I'm assuming it either runs on one leg of the 220, or they are doing something strange with the ground?...
Haven't tried it on 220 yet... 3/32 rods will pop a 20-amp 120 V breaker if you run more than about 4" of electrode at a time, so there's definitely a limit on 120 volt circuits...

It's an inverter welder so it rectifies whatever comes in to high voltage DC. No switch for 110/220 needed. It then converts that DC to high frequency AC, reduces the voltage (and increases current) through a small high frequency transformer and rectifies one more time through hf diodes to finally get DC welding current. Freaky little welder is half the size of a toaster and weighs 4 lbs. Many of them can make beautiful welds after some tutoring and practice.
I still like my 250lb AC buzzbox, but that stays in one place and I bring the parts to the welder. When I need to bring a welder to the parts those little inverter boxes are awesome :-)
The internal control chip tries to weld per your dial setting. On 110v it may want to draw 40 amps but no normal household here in the US has a 40A 110v outlet. Welder will work on 110v but will only do light welds.
When on 220v welder will only need 20A to run at it's full power. Pretty much every 220v circuit I've ever seen is at least 30A rated here in the US so these welders should run close to spec without popping breakers on 220v.

Many thanks for the informative post! :D
That answers it!

If you are looking for steel to weld check your local area for an industrial steel supplier. I have one a couple miles from here that does basic cutting, trimming, hole-punching for customers. That means they generate a LOT of cutoffs and shorts as well as a some nice laser cut shapes. They allow walk-in customers into the leftovers WAREHOUSE to buy anything they want for $1/lb mild steel, $2/lb tool steel, $3/lb stainless. They also have aluminum shorts but none of my welders do aluminum. They do want you to buy 20lb minimum but that is EASY to do when buying steel.
I got several 3/16"-1/4" plates ~14"x8" which I welded together to make a pellet trap. Material for the trap was just under $20. Have several other pieces set aside to make another spring compressor but I'm working that one out on paper first.
Another option is trash day garbage picking. I never drove around specifically to pick but found a LOT of good steel simply driving back and forth to work. All the steel people throw away that you never noticed before starts to GLOW BRIGHTLY once you start welding as a hobby :-)
I've picked up six 1.5" angle steel bed frames, dozens of feet of steel plumbing pipe, and many other steel scraps left on curbs for garbage day. The angle made a nice home brewery stand for a friend and I still have a bunch left. The water supply pipes are usually rusty on the inside and may have pinhole leaks... the reason they were scrapped. However, those pipes are still plenty strong enough for many other projects. Worst case the pipes are good for welding practice. Around here you can take your trash steel to a scrap recycler for ~$0.20/lb. Not much, but sometimes worth the trip.
Best wishes on your welding projects :-)

Thanks for the tips, but at the moment there's no problem- I currently work in a Fab shop... ;D
Literally have a hundred pounds or better off steel that I'm gathering up to weigh, and buy for scrap prices... 8)
