I recently picked up an old 330A/BP for my home shop. Tonight was the first time i tried firing it up. I found that the HF isn't reaching my torch. I've seen plenty of threads about No HF on these but mostly focus on the caps or contacts. The machine was pulled out of service and replaced with a new one for unknown reasons.
My contacts measure .008" gap and when I hit the pedal I have a good blue spark between both of them. The caps aren't original so I assume someone was chasing this same issue.
The settings I attempted are:
Amp Control: Remote
Contact Control: Remote
Output: AC
HF: Continuous
HF Knob: 100%
Large Lever: TIG
Amperage: Middle Setting - 70%
anything I'm reading says I must be losing my HF inside the machine. I have the side panel off and turned down my lights. While standing on the pedal I see no flashes or glow inside the machine other than the HF contacts.
The torch is a brand new cheapy air cooled #17. The ground is a brand new clamp on a cable I stole off my functional MIG for the moment.
What else should I be checking?
