It is a good question, but, unfortunately, there is no such
chance. Everything inside it is 3 phase, the 3 phase transformer, 3

Well I guess you can decide if it is cheaper to buy a single phase welder,
or upgrade your subpanel, or install a separate circuit for the welder. If
you decide to install a separate circuit for the welder you should take the
load for the phase converter into consideration. One horsepower equals 746
watts. It sounds to me that if you didn't have the phase converter, you
could probably use the welder on your existing subpanel. The more juice you
need for the welder, the harder the phase converter works and draws more
power. Your electric meter is also spinning more as that phase converter
Another option is to contact the power company to find out if 3 phase power
is available in your neighborhood and get quotes as to the cost to install a
3 phase service.
This welder's main problem is bad power factor. It uses a lot more
current than would a machine with better power factor. Looking at
power, my 60A circuit can produce 14 kW, which ought to be enough for
any welder or cutter. But this thing has a low power factor.
Why did you buy this monster? Are you planning to move to a commercial shop
someday? It sounds like it is more trouble than you need for a home shop
welder. My advice is to sell it and get something suitable for your
