recently bought a 2nd hand Kemppi MinarcTIG Evo 200MLP. the condition is pristine and it could weld any size electrodes all to my likings. the problem i am having with is on the TIG side. whenever i Tig weld, whether on 2T or 4T, and on any other settings, the set welding amperes would fall down from, say a setting of 110A to 5A in less than a 30 seconds or so. it can't hold the set amperes at all. in short, it can not weld on TIG. i don't know if it is the machine that has a problem or me who needs more training and knowledge about the right settings of the welder. i am ready to get this returned to the seller but i want some opinions first regarding the problem. if majority says i need to return the item then i will send it back but if i can get some help to get this working right then i will keep it. but of course i need somebody to help me out. thanks and hope to hear from someone else soon.
