ID:	667759So after toiling for days, removing circuit cards for relay testing and blowing fuses testing various circuits and Oh yea even trying to make sense of the Schematic I could not figure how to replace that stupid SAF blowback torch that is awkward to use, really Bubble Gum design and parts are not available for anymore. The problem was trying to find the switching circuit for energizing the relay board for air and plazma so that an ordinary plazma gun could be utilized. The whole time the answer was in front of me but I never noticed it. So to test I charged the Jr. with air and set it to low removed the leads #206 and#207 from the air switch and installed an external push button starter switch in the white leads and pushed the gun down on the metal to be cut and nothing happened until I pressed the button on the external starter switch and Whalla!...FIRE! and air. So now all I have to do is get a gun and some minor pieces to convert and now I know where to put the two leads from the gun switch. I will probably parallel the wires off of the existing air switch so that I don't have to remove the sucker and store it somewhere else. Anyways glad I didn't have to give the Jr. to someone who would've probably set it out in an alley somewhere for trash.

    Why not just replace the air switch?? Instead of farting around with an external push button or toggle switch....

            I dislike it when I want to read a post but I have to dissect it beforehand because the poster can't punctuate it. Spelling is one thing and over lookable but cramming everything in a lump makes for a hard read....
