Good afternoon all, bit of an emergency(ish) question we put our hypertherm powermax125 back to supplier since it was playing silly buggers when it was turned up above 105a, they have just phoned for an order number and told us they solved it by swapping a phase on the plug, is anyone in the position to confirm if this can effect a hypertherm plasma, In my mind it is run via inverters and a backward phase shouldn't make a jot of difference, the double-cheek part of it is they put the damn plug on themselves... I dont like falling out with suppliers, but I like less being taken advantage of. Many thanks in advance if anyone can help with this question. - Louis
