I just finished a 2 day TIG class - my first time welding. We welded small (maybe 14 gauge) stainless plates. I used a Miller Synchrowave
250, but near the end of the class I switched to a Lincoln Precision TIG 275. The HF arc start on the Lincoln seemed MUCH cleaner than the MIller. The Miller would wander and buzz a bit until I got the current up to the right level, after which the arc was OK. The Lincoln started with a nice tight small arc right from the start. I was probably at 60-80 amps for these welds. Is this difference a real one, or was the Miller operating abnormally?I was looking at buying an inverter, not one as large as those in the class. The drift I get here is that Miller seems to be preferred for TIG and was leaning to Miller Maxstar 150 or Thermal Arc 185 (not sure about needing aluminum), but this arc start difference makes me pause. If the Synchrowave was not misbehaving, would a Maxstar or Thermal Arc start the arc more like the Lincoln?
