SOURCE: Plasma cutter

in order to cut the thicker steel just boost the air pressure this will allow you to thourghly blow through the steel. just remember not to turn it up too much. this should do the trick. please rate

SOURCE: hypertherm plasma cutter making weird air sound from inside unit

Open the cover (only after a day of not being plugged in).
Check the airline that comes in through the back of the case.
The air line has either fallen off or has a hole in it.

If you are a technician and don't mind working with thousands of volts of electricity that is inside the case, then and only then can you plug it in. Safety First. Rember the voltages inside this unit are lethal. It will not give you a second chance.

If you feel you are qualified, then plug it in and start it up, use it as normal, while at first watching from a 2 meter distance, you may immediately see and/or hear where the noise is comming from.

DO NOT under any circumstances put your hand or hands inside the box while it is live.

Try running a WOODEN stick (at least a foot long) along the length of the airline inside the case and around the valve as it enters the case. The sound should change in pitch when you find it.

If you think you have found it, DO NOT touch anything inside, until you have both DSCONNECTED THE UNIT from the power source and WAIT ONE DAY before putting hands inside the unit. Any storred or residual energy will have discharged by this time, making it safe to work on. Safety first. The voltages inside are lethal. This aplies to all Plasma Cutters. Good luck.

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.

SOURCE: my plasma cutter just flashes fault everytime you

check the main lead to the torch,if there is a cut or any hole in the rubber coating it will show fault,the unit uses high frequencey so if the lead has a cut it wont fire up.

SOURCE: spectrum 2050 plasma cutter .

Check compressed air pressure is in limits otherwise unit will cut out. Try adjusting the pressure up. also make sure the supply pressure is correct as it may not be your plasma cutter at fault.

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.

My miller spectrum 701 was set up for 1ph 230 and got plugged into 460 and fire shot out of it several times.what would it take to fix it?


I'm not recommending that you do this, but if you were to open the covers you'd be able to identify visually the blown boards and on the boards are the codes for re-ordering. This is not a guarantee that other boards won't be fault, but they should be ok.

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..

Need to switch 3 phase to single phase


An electrician can provide you with a TRANSFORMER that has a single phase primary and 3-phase secondary. The secondary would connect to your Plasma Cutter. He may be able to find you a used one. Ask him what you need for the size of your Cutter, and you may be able to find it on Ebay.
