Hi all.
I'm new here and I have a question about my synrowave 300.
It's an old unit, serial number HF870894, and the high frequency start only works on high range. It works on continuous high frequency in low range. I had leaking capacitors so I replaced all 3 with millers replacements (higher voltage than the originals). When I first got this welder the HF start worked at the lowest setting on low range.
