Oerlikon Citoarc Tac 173 3-Phase?

[Ascendant Access]

Hello,
The company I work for has purchased an Oerlikon Citoarc Tac 173 Tig welder for a good price however it's come with no manual and has the capability of plugging into 240V however we're not entirely sure we can plug this directly into our 3-phase ring-main. There's a busbar inside the welder with the option to switch to 3-phase and I've had my electrician look at the welder to see if he can work it out but he's not confident enough to plug it directly into our 3-phase and give it a go. Can anyone advise me on if switching the busbar over to 3-phase is enough and we can use the 240 lead already installed or do we need to install to a 3-phase lead into the welder?

Thanks for your time.

Ross.

Looks like the welder can be configured to use the 415 volts phase-to-phase across two phases, so not an actual 3-phase machine.
Post #8 shows the busbars, but not in enough detail.
Post #6 of this thread says that there are instructions for power configuration on the inside of the case:

Hello from Anglesey

Hi everyone, I used to do a lot of welding years ago for a boatyard, but have been out of the game for a few years now. I decided to take on a project a year or so ago & it's snowballed out of control & has ended up with me purchasing a few tig welding sets. Some great & some not so. I...

Thanks for your reply - and thanks to whoever for moving this to the correct forum!

We've managed to get some voltage on the input to the main contactor but the contactor itself isn't pulling in (the machine isn't even turning on when we manually push it in). I'm going to take it to our local welding supplies shop next week to see if they can get it working.

Thanks again!

Ross.
