So I finally got this monster going after a fair few problems with wiring it up and giving it a decent service. There was a phenomenal amount of gunk in the water tank and it had blown a fusible link in the water line which didn't save one torch (the best one) which also appears to have blown. Here's the front panel with my best guess as to what all the switches and knobs do: Some of them I am fairly sure about but some are either guesses or unknowns. I melted a fair few electrodes before I got to this stage: ...and now it seems to be working (with the settings as per the photo) I'd like to know exactly how the switches and knobs work. My big confusion currently is how the foot pedal overrides or works with the master current level set on the big knob. It does seem to change so even if the master control is set to say 75/85 amps, putting my foot down on the pedal appears to override that. On the back of the pedal the low level is set to 1 and the high level 10 but does that map to the level set on the master current control or is it pro-rata, depending on where the master level is set? If anyone knows for sure what all those settings and hieroglyphs mean, I would be most grateful for a translation! Oh and if anyone has a manual in english I'd be more than grateful. Thanks Screwdriver.
