  • Pro 300

    I have 2 Pro 300's, both bought at the same time, around 2004. One has never given any trouble but the other one wont weld or put out power when it gets wet. It just has 00 voltage and amperage. In the past I just let it run all day and it would finally start welding again. Anyone have the same problem?

    Weld 100% better running at 61.8 HZ high idle, and quite likely your slip rings are real dirty. Merely clean with a Brillo pad green, or purple with the engine running
