If you buy a mig welder don't get one from China unless someone you know gives it a thumbs up. I bought an el-cheapo one on ebay to replace my Italian made mig welder. I have never been able to use it properly. I get wires sticking in the weld, spatter, blobs etc. I had no trouble with my old mig but the handpiece was worn out and the cost of the handpiece replacement was the same as a complete brand new inverter welder from China but it is total rubbish.
