Air pressure is probably falling off. This can be caused by several things. The compressor that is too small to keep up is usually no.1. the 1250 is a large unit amd requires a sizeable air source. A way to test would be to connect a compressed air bottle from a welders supply.

Powermax 1250 low air flow

check the blower, it may need to be replaced, or you may need to replace the blower vacuum switch. you can jump the blower vac switch to test if it is the problem. if so, make sure all air lines going from the switch to the blower to ensure no cracks in the rubber tubing.

I have Hypertherm Powermax 600 and the green OK light does not come on at times. I will let it set over night and it may come on or maybe not. Driving me NUTS!!! Please can you help. Thanks

you might have a bad relay on your circuit board. They arc and spot weld themselves at times (nothing a sharp hit can't fix) Replace the relay with a higher quality one if you can.

I have a Powermax 380 and it will not cut even with new consumables and filter.

Hypertherm is tight with their dcoumentation. they hide the old stuff quite well. and the hotlinks are just to the catalog to get you upgrade and buy more of their product.

Right off hand without documentation, I would still open it up and take a look at the inverter portion of the unit first. If it has been used a great deal, there is a good chance the capacitors of the inverter or the power supply section feeding it have failed. If it was used longer than the duty cycle suggested, this could easily happen which would also raise the question of the coondition of the inverter transformer and the main power transformer and would mean serious time with a test meter. With that said though It is likely not a huge a problem that is causing it to not work, it is likely just a handful of parts- it just takes a little time to find them.

The gas light come on and flashes and wont cut. I have changed all the nozzels on the torch and still nothing?


Gas light goes on when you have an air flow or pressure problem. Do you have enough pressure? you will need at least 120 psi at the compressor and 75psi at the plasma machine. Do you have enough flow? You will need 20 SCFH and a 30 gallon compressor reserve tank.

Let me know if this help. Please vote.

My Hobart 250 airforce doesn't start

On the main circuit board for the power supply, there is usually a thermal fuse installed, its a sealed unit and is not servicible, look for a black epoxied case,approx 3/8x3/4 long, with 2 leads coming out of it. Inside is a set of bi-metal contact points which serves as an over voltage/over current protection. These contacts deform/corode over time and it sounds like there not contacting properly. As soon as you try to load the machine, the current passing through this high resistance heats these contacts up, and shuts off power to the unit. I am not familiar with the guts of a hypertherm, but have extensive experiance repairing inverter based plasma cutting equipment, and i have encountered this before. I assume hypertherm must have some equivelent to this thermal switch inside the power supply.....Good luck..
