Troubleshooting help My plasma cutter is not cutting does the electrode need to be in good standing. I have good power and good air to it but it is not doing anything when i try to cut. The electrode is a little buggered up.

Hi:
There is no mention of the Thermal Dynamic's gun model, but i will suppose that it is a SL60 or a SL100 which are replacement guns for any model of plasma using the proper adaptor.
Your problem could be the start cartridge which go bad now and then when the gun is used as a replacement of a hammer to make the cut piece to fall.

The way to check if your start cartridge is in good condition is by checking the low part of the cartridge, push it up (or down depending on the way you handle it) it should freely slide inside and return out.

Good luck.

Hi:

Miller plasma are pretty realiable. Without more details; what you need to do is check the contact tip and the electrode if these ones are won, replace them. If still doesn't work; check your air pressure; main source must give you at leats 90 psi and 9 SCFM of flow,

Good Luck

Some times when I use my plazma cutter its a cut master 42 .I would some times have to turn it off and turn it back on for it to work .And here lately all it does is air come on and off its like its has a heart beat and then have to cut it off again . I have replaced the tips and electrodes .And nothing .I have took thee electrode out and clean the white dust build up and works fine for a little while

Try using fine sand paper and clean the tip of electrode and the thing that looks like thimble, another solution was don't tighten tip cover too much back off a little til you ge good contact. some units don't like to be clicked ON without making contact with working metal, you may get two or three clicks and then nothing til the air stops flowing.

check the main lead to the torch,if there is a cut or any hole in the rubber coating it will show fault,the unit uses high frequencey so if the lead has a cut it wont fire up.

Try turning down the juice. Tungsten is very durable, but is prone to melt also at excessive torch output.

If you have a bad air supply then the moisture in the air will cause the torch to cut off and the cut quality depends also on air supply,speed,metal thickness and condition of your consumables,meaning your electrode and other related parts in the torch tip.Hope this helps

in order to cut the thicker steel just boost the air pressure this will allow you to thourghly blow through the steel. just remember not to turn it up too much. this should do the trick. please rate

Depending upon the design of the torch (e.g., orifice diameter), electrode design, gas type and velocities, and the current levels, several variations of the plasma process are achievable, including: * Plasma Arc Welding (PAW) * Plasma Arc Cutting (PAC) * Plasma Arc Gouging * Plasma Arc Surfacing * Plasma Arc Spraying
