Davida , post a photo of the back of the set has it got two low voltage heavy current inputs plus a 240V mains lead for powering the electronics ? To me at first sight I assumed it was a DC TIG controller only because of whats on the front panel but then the Westermans site does also state its AC/DC so they should know better than me , there is nothing on the front panel that connects to the necessary high current power source its all about output control so there must be somewhere to feed in .
Unless you have the machine that goes with it will be real difficult. SPec plate says it runs on 30V AC and without drawings of the connector pinouts, you owuld have no way to connect a 30VAC supply up if you had one.
It's B and C on the 10 pin at the rear for the 30 VAC however you also need to have a DC voltage present accross the terminals or the HF will not fire. The TU series do not have a contactor inside therefore you'll end up with a live torch all of the time with a non switched power source - compatible Kemppi power source units are the PS or PSS ranges
I agree with Shennion that it looks to be a DC TIG controller but surely Westermans know something about the equipment they are advertising ? So if you use an ac supply into the unit instead of dc will it then weld aluminium ?
It is AC/DC Fact. But you need to supply it with AC or DC from its relative Kemppi Counterpart. As the man said before. PS2800 PS3500 PS5000 WHICH ARE DC ONLY, or the AC/DC Machines, PSS3500 or PSS5000. I was a tig HF Unit for the Kemppi Multisystem.
And yes, with much knowledge and faffing about it would allow your oxford to weld ally. If you value your time, a fronius would be cheaper.
