Just used the plasma cutter for the first time ( I have used a Miller plasma cutter in the past). I was using it for 10 minutes on and off, the torch started to go out, I pulled the trigger a few more times and the overload came on. Now, everytime I pull the trigger the overload light is lit, no attempst to spark and air runs for 10 seconds or so. I let it sit for an hour, still does not work. I inspected the tip, nothing looks bad. The air filter was dry, I have two inline air traps, one at the compressor another at the inlet of the plasma cutter. The air was cold since the shop had not heated up yet but with I do have the traps. What should I try?
