I have an older Miller 180SD that's never caused a problem, but since moving my shop a couple of years ago it seems that the HF TIG start is popping the GFCI outlet breakers in the rest of the shop. The welder has a dedicated 50A line from the 100A subpanel and the GFCI outlets are on completely separate runs so I'm thinking that it's some RF component causing the trips. I don't recall the trips when running the welder in stick mode. The house GFCI isn't tripping and I never say this at the old house so I'm thinking the new GFCI outlets are somehow more sensitive to noise.
So I'm thinking of making a reactor for the supply line, maybe get rid of some of the noise the welder can throw on the line. Not sure if I need to hit just one of the hot legs or both - thoughts? I'll likely use 3-4 wraps of 6ga around an old transformer core, should give a few hundred micro Henry. Alternatively I could buy a 50A line reactor off eBay for ~$100.
