    HMW,

    You've got to be careful with the Power Factor Correction. It does not come without a price (and I'm not talking about the price to have it installed)

    PFC will cause your machine to draw much higher amps when it is just idling. PFC really only makes sense to those who are using the machine in a near continuous mode. For most hobby/non industrial users, the PFC will drive your electric bill through the roof.

    Just my .02.

    You will eventually weaken that 50A breaker.

    A machine should always be wired for the maximum input.

    I tried the 50 amp but would not hold. Then I got looking at the spec and it says at 230V input and 200 amps output, the draw would be 77 amps. At 230V input and 250 amps output the draw would be 96 amps. I put in a 60 amp breaker and it did Ok but i only stayed down around 150 amps. I only borrowed it anyway. Also alot of breakers will hold at higher amps temporarily it seems. But not for extended use.
    I noticed they make a power correction kit that will reduce the draw by around 25%. That might help those who can't get enough Line feed
    I ended up buying a SW180 and it draws at 230 Volts input 54 amps at 150 amps output on AC TIG, I have tripped the 50 amp breaker its on when I have it at full power for very long. I need to swap breakers with the one I had for the SW250

    We checked ours one day and it drew something like 35 amps at 240 volts doing no welding, just runnning. Seems odd to me to draw that much just running but it seems to work fine.

    It'll use every bit of that requirement. Mine does.

    Especially when running on AC with the balance control above 4 or 5.

    You'll need at least a 100A circuit for it unless you can run it at 460v.

    Syncrowave 250 input question

    Syncrowave 250 I'm looking at buying has the following input requirements. Does this thing require a 100 amp service at 200/230 volts? If so i won't be able to run it since we only have 50/60 amps

    Thanks in advance for any help

    INPUT:

    VOLTS 200/230/460

    AMPS 105/8/92/46

    KW 11.4

    SINGLE PHASE
Working...
