Hi, I would like to introduce myself. I am an advent Offroad hobbyist that builds and modifies my own Buggys. I bought one of the China combo Plasma cutter welder off Ebay a few years ago and it only lasted a little over a year before the Plasma cutter and Tig welder stop working. It appears to be the HF arc board however I can not find one for this model. Since then I have been looking at the Everlast product line because it comes with a 5 year Warranty and appears to have good support. So here I am.
