Wiring for Hypertherm 1000

[WheelingCJ5]

I just picked up a Hypertherm Powermax 1000. From reading the little manual that came with it, it looks like it can run on single phase or three phase.

What do I need to do wire my garage for this? I have some knowledge of wiring - I already wired a 220 outlet for my welder, but that is only 3 wire. What's the difference between single and 3 phase, can I even wire it for 3 phase in a residential area?

Any help would be greatly appreciated.

I thought it came in either three or single phase not both :confused:

More than likely, since you are in a residential area...no on the three phase.

Three phase is not just a different breaker or wiring method, It comes from the the grid that way. In 3 phase, you have 3 legs of power that are 120 degrees apart, if you looked at them on an oscilliscope.

If it is a non changeable 3 phase machine and you only have 1 phase you can get a phase converter to go from 1 to 3.

The newer hypertherms are multi phase machines. Your house will have single phase.

A Hypertherm Powermax 1000 is an Inverter/Switching power supply machine and as such will accept any input voltage from 200-600V in EITHER single or three phase.

It is going to be wired the same as your welder but depending on what welder you have it may require a larger circuit breaker. For single phase @ 240v it is listed at 42A and with a inverter having a much smaller inrush current than a 60Hz transformer machine a circuit breaker in the 60A range will likely be required, check your manual.

Be careful and make sure that you are completely sure what terminals you are wiring to inside the machine as the presence of the “third leg” in three phase power is generally what the machine senses to determine if it is hooked up to single or three phase power.

Cool, that's what I needed to know. Thanks guys.

Good to know.

There we go! Lots of great info there.
