See if the torch electrodes MIGHT be stuck... welded together. They have to arc and then separate or unit will shut down.

Cutmaster 81 plasma cutter when turned on, starts normal but air solenoid keeps going on and off. What could be the problem?


Hi:

Sound like you have a faulty start cartridge, probably you used the torch handle to bang a metal part to make it fall. This is a common problem when using the gun as a hammer. Just replace the start cartridge. Before changing it; check the cartridge's lower end, this must move freely up and down.. If you did replace the cartridge already then probably your output power pc board it's damaged.

Hi I have a hobart airforce 250ci 2 and a half year old lightly used plasma and the power doesn't come on


Check your ground and make sure the ground is clean, if not sand it slightly where it's shinny then try tighten the ground clamp and tighten the ground clamp on the machine itself. Be sure the breaker is not tripped for the machine in the main electrical panel as well check that the electrical cord has not worn down from use, you may have to replace the electrical connector if it is badly worn. you can buy at any hardware store, you will want to buy a 15 amp male connector. If this does not sole your problem please let me now for more help. also be sure air is working for the machine.

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..
