Be aware of o my situation so might help you doing business with Mac Lee their sales director. I bought a welding machine from them - they are not the manufacturer. late on shipping, pure boxing that's not a problem I could live with that. But I open the box, and you realize machine was designed for Indian market (cable colors and power) But I was ok, mistakes happen - was able to fix the power supply and finally welder was turn-on. Yes stick welding works, cutter works but mit and tig are dead. Not even one spark. Like I said, I am not blaming manufacturer (1 in 1000 products can have some issues). And if i would deal with the manufacturer 100% will get a new machine. But Mac Lee sales director unfortunately not really willing to solve the problem. First solution was completely wrong, second solution same thing didn't help - he claimed its a operator problem. Got finally my money back thanx to Alibaba.
