Hypertherm Powermax900 generator power?

admin

Howdy. First post...I purchased the subect Hypertherm900 off of ebay a while back and would like to build a portable set-up. I will also be using a Ironman250 mig with the same generator..My question is this - would a 10kw generator (single phase, constant 40A @ 240V, 50A surge) be adequate for most use? According to the specifications, the Hypertherm900 requires 47A @ 240V to reach the maximum cutting output of 55A. Max for most of what I will be cutting is 3/16" aluminum and 1/4" steel. I will also be running an air compressor on the same generator, but I'm thinking (hoping?) that I could stop cutting when the compressor is running. Here is the generator head I'm considering:http://www.northerntool.com/webapp/w...6970_8795_8795 Here are the Hypertherm900 specs I found:http://www.hypermax.org/Specs%20900.htmThanks in advance for all replies.  Attn:  Jim Colt - I was told on the Hobart Weld Talk forums that you would be a particularly good person to ask the above.http://www.hobartwelders.com/weldtal...ad.php?t=33166
Reply:You can run the 900 on a 10kW generator......although you may have an occasional issue if the compressor cycles on and you are cutting at maximum output power.....worst case....the arc will extinguish and you can just pull the trigger again and it will refire.Also remember....if you are cutting thinner material, simply turn the power knob down a bit...and the input current draw will be lower. There is no real need to cut 3/16" material at the full output power of 55 Amps....40 Amps will do just fine.I used to own a Powermax900....and had the opportunity to use it in the field.....I had a 10kW (Generac brand) generator that worked well with it. I now have a Powermax30, Powermax45 and a Powermax1000.....but they stay in my shop most of the time.Best regards and good luck!   Jim Colt
