Firirng issues PowerMax 30
Help! Not sure what's going on. Tried cutting copper the other night. So today I went back to steel. Cutting 14 ga. Cold Rolled steel. First 3 cutouts went ok. Minimal dross. Looked ok, noticed top side had a weird look. Anyways, tried cutting another piece and lost signal. Changed consumables. Worked ok, then quit. Keep losing signal. Wiped surface of metal. Ground directly to metal, is my torch head damaged? Is there something else I need to look at. Did I accidently change a setting on my plasma cam dhc2 basic height control. Do I need to buy a new cutter? Agh, every time I get ahead, I fall back 2 steps. This sucks.

Re: Firirng issues PowerMax 30
Robert,
Remember that you are using a hand torch for mechanized cutting. The Powermax30 was never developed as a mechanized cutting system, we always recommend stepping up to the Powermax45 with its additional power, duty cycle and an available machine torch.
Cutting copper is similar to cutting steel of about 3x the thickness.....it has to cut slow, which increases the arc voltage at the torch....which increases the used power in killowatts, more heat in the torch head.
There are many users with the Powermax30 on a cnc machine, and I understand that it is done as the 30 is the lowest cost Hypertherm unit, however it will never hold up in this application as well as its bigger brothers.

LOL, thanks JIM. I definitely learned the hard way. LOL but, on the positive side. I fixed my torch! I'm up and running again. A new Crimp, screw, washers and nut. Firing better than before LOL never cutting anything other than steel, until I can afford a new Powermax 45! And if anyone questioned the durability of Hypertherm , It's a Frickin tank!!!

Re: Firirng issues PowerMax 30
Glad you were able to fix it....likely the main electrode connection in the torch overheated
from the looks of the pics! Good luck and keep cutting!
