This is for anyone who does TIG work. I'm posting it on a couple of boards so apologize in advance if you see it twice.
I have a 10 year old or so Miller Synchrowave 250 AC/DC welder, which has stick and TIG capability. There is a switch on the panel that allows three choices: Hi-frequency start, hi-freq continuous or off (scratch start). Scratch start gives an excellent arc and welds perfectly but there are occasions where I need the start-only feature. When I first got the machine, it started fine but I got a little arc wandering. However, the start feature has now stopped working completely so I am forced to use scratch-start. Does anyone know whether this is related to the points on the machine or a bad switch or something I have not considered?
Thanks, Hollis
