Just bought a kamanchi 275 mig as a second welder. Only cost me £75. Fired it up and works well. Ive never heard f the make before are they reliable or have i just bought a dog?
A friend of mine ran two Kamanchis when he was busy a few years ago. Didn't hear him complaining too much and I don't think they were a bad price at the time, around a grand ISTR. He's since swapped to a thermal arc set which I find quite good, but he didn't get on with at first.
At the end of the day £75 and it works you can't really complain. If you do I'm sure there's plenty of people would have it off you for some profit.
