Compact yet very powerful. Have only ran on 110v 220 should be even better. Buy a good 10-2 extension cord if you need it movable power cord not too long. Leads fairly short. Burned thru two pounds on 3/32 7018 only issue was negative voltage error13.4 just unplugged and it reset. First welder purchased, did order gas lens for tig and different collets. All in all only used two weeks seems like high quality product.
