So I recently acquired one of these, a Kemmpi MasterTig 1500 DC TIG welder. It's old but the chap who sold it to me swears I'll really appreciate the quality when I get it all hooked up. And there's the rub. I don't know which connectors to hook up. Hopefully I won't seem such a dullard after you've seen what I've got to play with.
The package included a Kemmpi foot pedal and a couple of different TIG torch leads.
Below is the hose with the 2T switch I mention below. The four-pin pug attaches to the back and would displace one of the two pedal connectors.
Only one torch was included, and he was pretty clear that it had probably struck its last arc. Anyway, here's the only connector on the front, which connects to the controller on the pedal.
Here's the rear view. Four pin connector, a couple of Dinse connectors for earth/MMA wand, a gas inlet and a really odd-looking gas outlet...
This seems to be one valid way of connecting the hose with the controller on the torch:
My question (1) is really whether I can use the pedal with this torch at all, if I hooked it up like this. Does the pedal need both its outputs connected to work?
Question (2) is whether having an unshielded connector for the torch's electrode is "safe" ... a moment's thought makes me think that on this DC set it would probably work in DCEN mode, so that curved gas pipe sticking out the back of the unit is actually just a "ground" (and won't kill you if you touch it). I'd prefer confirmation over real-world testing...
Then there's this hose and (ancient) torch, which I've connected to the only compatible connector:
Again - is this a safe set-up based on the theory of that gas pipe being the earth connector? And as this has no switch-gear it presumably has to be used with the pedal?
Then there's this other hose which he supplied:
It looks as though the left-hand connector is compatible with the gas-outlet pipe/earth on the rear, but does anyone recognise what would fit on the connector in the right-hand side?
I'm guessing that since the pedal has a four-pin controller -- like the on/off switch on the torch -- that it can transmit an "arc-off" signal to the box. Does anyone know off-hand how it determines whether you'd just like to run minimum amps through the torch or whether it should turn the arc off completely? Sorry if this is unclear!
Best wishes
