    Default Lincoln v350 pro on single phase

    g'day,

    got out the chance to buy a lincoln 350 pro

    can run on both single and three phase But what sort of single phase power conditions would I need?

    can the machine run underpowered I wonder?

    says in the literature can operate on virtually any poer source.

    i have a good industrial 32 amp outlet running another welder and wondered if the pro could run (with limitations ) on this as well?

    a friend seemed to think I'd need huge power and mighty thick Leeds but it is an inverter after all, so what do you reckon?

    any electrical dudes out there?

    regards

    See if you can find a manual on line. My Dynasty is like that too and the manual shows a graph of output for various settings and input voltages.

    Looking at page 8 of the operators manual http://www.lincolnelectric.com/en-us...V350&type=text you will need 85A single phase at 230V input to attain 60% duty cycle at 350A output. You'll need #2 cable, 6.5 mm conductor diameter. If you run the same input voltage but three phase you can get the same output from 42A input supplied by #8 cable 3.2 mm (x3 + ground of course). So you're voltage phasing doesn't really limit you assuming you can get the load supported at your point of use. The choice appears to be dictated primarily by the capacity of your distribution panel and the price of wire in your area - the welder doesn't seem to care as long as you're giving 230V.
    I run my C300 on 6-6-6-8 otherwise known as 6-3 cable (downrating of the ground is permitted here) with a 75A 2-pole breaker 240V two-phase and have never had a problem.
