L-Tec Service & Repair Forum

Hi, I have a L-TEC brand plasma cutter pcm-7501, p/n 32905, serial a93b41632 and was wondering if I could ask you a question or three about it?My questions are,it will power up fine, and when you select air test, that function works as well. There is no fault light on, but the problem is that the unit will not do a thing when you push the trigger. We have tried changing the tip consumables out with new parts, and checked the trigger also. It tested fine. Is there anything that I could do or test before I bring it in to get it tested? Is there a common problem with these machines that maby i could fix? and lastly, If the circuit board is bad, how much for one and is it even worth fixing this machine.Sorry for the long post and thank you for your help!Ken

I have the subject plasma cutter and am trying to use it in a X-Y machine operated by my older computer. It works most of the time but it seems the high frequency start is killing the computer on occasion. Is there a way to disable the hi frequency start circuit ?Thank you Bill

The problem is probably in the trigger or broken wiring back through the leads. If you have any of the electrical drawings, they should show where to close the connection inside the power supply to fire the torch. If it fires that way your problem is in the leads or trigger.
