PM-205 Plasma not working

[jas329]

Mike PM Sent.

Mark, when everything is screwed tight, the cup compresses the electrode against the tip and there is no movement in the tip. When not in use the electrode makes constant contact with the cutting tip. It looks like tip can be pushed back about 1/16" before the swirl ring makes contact with the torch body where the electrode screws in.

Just pushing in the electrode by itself it has about 1/4" travel. looking at the small holes for air flow near the electrode, when the swirl ring and tip is compressed against the electrode it seems like the holes are almost covered up by the torch body. when the electrode is fully compressed in agianst the torch body the holes are completely covered up.

The spring return on the electrode is decent, seems a little rough/rubbing when pushing it in though.

For anyone interested, Everlast shipped a replacement for my PM205 after the plasma went out. Everything on the new unit is functioning great. Hopefully this one doesn't quit working, but I feel good knowing that Everlast will exchange faulty units. Thanks!

I guess for anyone that is still interested and have a similar issue with the plasma cutter, if the electrodes are pitting faster than normal, best to check the connections to the unit. Make sure the ground clamp is connected to the positive port on the unit and the torch is connected to the negative port. You should be able to hold the torch up in the air with the unit plugged in and air flowing, the torch should spit out about 1/4" electric bolt. Now the plasma is working like a charm and the electrodes seems to be holding up just fine.

oh forgot to mention that it Mike and Mark were very helpful, I got a call from Mike that same day I PM'd him and he was very patient as he walked me through things to check on the machine and asking me about my setup. It was helpful to pick their brains to get a better understanding of the machine. The next day I was able to solve the problem (it didn't take 9 month to fix, I just forgot to post it earlier, sorry). I gave Mike a call to let me know the good news and he was kind enough to give me some pointers on how to set up and use the machine to get the most out of it. Thanks guys for all the support.
