Having fun today cutting some metal, and getting towards end of my cuts when the torch quit firing. I’m using a machine torch XT40M with the CNC kit. Was running fine all day, but I did just try some 1/2 in plate and it was struggling thru that (mostly due to my too short pierce delay settings)…
I tried a few more cuts - nothing. Time to start troubleshooting…
First - checked work lead - made sure it had good connection.
Checked the tip, ring, electrode - made sure everything was ok. Went ahead and replaced the electrode and tip. Wont fire.
Front panel is all green - no error conditions - air is good, cup sensor is good, power is good.
Checked all wires to LS control box. Reseated CNC connection RJ45. Turned off / back on. Test fire - nothing.
I did the manual torch fire, and I can hear the relay clicking when I tell it to fire, but nothing happens on torch.
So I have a hand torch as well (XT40). Hook that up. Pull trigger - nothing. Release trigger, post flow kicks on and air comes out for a few seconds. Pull trigger again - nothing, post flow comes on when I release.
Tried this a few more times, but no errors on the front panel, and no pilot arc. Wondering that I may have done something vs it just being a random failure. It’s rated up to 5/8 plate, and I was running at 22 ipm - it was not liking the pierces, but it did work, but then decided it was done.
In any case, system is under warranty and will be going in for service tomorrow. Will try and report back what the issue is, but in meantime, if anyone has any ideas to do some more trouble shooting…all ears…
