The guy I've been machining parts for has one , and the HF start is weak -
he often has to touch the tungsten to the work to initiate the arc . I've
looked thru his owners manual , and can find no reference to adjust an air
gap , which has me wondering ...does this unit use an air gap to produce HF
for start ? If so , where can we find info on checking/adjusting it ?
