I bought an 82i because of duty cycle and ability to do 3/4". George recommended the tecmo ptm-60 for lower amp stuff with a finer tip as the stock ipt80 hand torch only goes down to 1.0mm tips. I hooked everything up and it wont work with the ptm60, errors and misfires detected with THC. THC off it works okay, still will missfire but I can usually get through a program. Everything works great with ipt80 torch. I have verified ptm60 wiring, tapped into raw voltage past cnc port, moved machines around shop, grounded table and plasma to conduit, put ferrite chokes on everything. Tested different F bomb programs, verified versions of software. checked consumables, checked cup contact. Ptm60 torch will fire continuously hand held when jumping the dangling trigger wires.
I just don’t know where to go from here. I’m suspecting RF interference, but nothing has changed in all my extensive trouble shooting. I did some trouble shooting with Danny/LS and he gave me the go ahead that the THC is operating correctly. I’m just starting to suspect for one reason or another the torch is not very compatible with the Langmuir Systems table.
Any ideas? Any one running an 62i/82i with genuine tecmo ptm60? Thanks guys.
