Plasma cutter
I have a Plasma cutter, I have the air set up according to the pressure they suggest and I start with a new tip, it will do fine for a bit but them it will just cut out and blow air. I can clean the nozzle and it will do ok but not good. What am I doing wrong to burn out the tips so fast?

I will check the ground but don't think that is it. After I clean up on the tip some it works good but not for very long.

Re: Plasma cutter
Are you using an air dryer setup? I understand they're beneficial to the lifespan of the nozzles...

Re: Plasma cutter
I don't think that is fixable.. You had better just go on and ship it out to me so I can properly dispose of that thing for you...
Naw check the ground.... and how far are you keeping the tip off of the workpiece. Most people hold it to close, and that creates problems..
How much air pressure? Do you have enough volume? Or to much?

Re: Plasma cutter
I'm thinkin' that dry air is not much of a problem in June in Needles, CA. Humidity is probably hovering near zero. Chris doesn't know that not everybody has rain every day.......
BTW, Leather gets new job, moves, and suddenly can afford a new plasma cutter? Pay must be great or Angie's wearin' the same shoes one more year.

What make is it? My Miller will do that when the electrode wears out.Leatherneck wrote:I have a Plasma cutter, I have the air set up according to the pressure they suggest and I start with a new tip, it will do fine for a bit but them it will just cut out and blow air.

I don't always show my signature. But when I do, it's in this area.

It is a off brand ( I think) Century or something like that. I will replace all the parts in the gun, go at it for 10-15 seconds and it will do it again. I talked to a welding supply shop and they said it might be water in the lines, they said that will mess them up.

Re: Plasma cutter
An update would be nice, figure it out yet?
Are you using an extension cord? Have you tried other outlets? The amp sensing capability will shut it down when the supply voltage goes too low and/or the amps go to high for the house side.

Re: Plasma cutter
The Plasma cutter is a century brand. Putting a water separator is a must, letting it run (not cut) for a couple minutes before cutting has helped out as well, that helps dry out the air inside the machine. It is doing a lot better, not perfect but man it cuts nice/fast when it cuts.

Re: Plasma cutter
Turn the amperage all the way up and clamp the ground to your part not to your welding if you are doing so. A water filter will help but it sounds like you are having other issues. Don't be afraid to drag the tip across the part you are cutting. The tips don't last as long but it is a heck of a lot easier.

Re: Plasma cutter
I have an automatic drain on the air comp. tank and I let the air bleed for 10-15 min out of the plasma cutter prior to using. I would think even in a dry climate the compressor still can have damp air. I have an air dryer but have not used it yet on mine. and I am High desert so. ca. and dry as well.Leatherneck wrote:The Plasma cutter is a century brand.
