OK, just figured Id pass this information along. I just got a machine torch for my Razorweld cut 45 and after installing it would just fire upon turning the machine on for about 3 seconds. Then air would continue to come out constantly. I realized the machine torch had 4 pins wired. Pins 1, 3, 6, and 9. Only pins 1 and 9 need to be wired and the other two (3 and 6) need to be removed. Its funny because I bought this torch used but in brand new condition and it was purchased directly from Jasic. You would think they know how to wire their own torches?!?!?!?
You would think so wouldn’t you. 
Would that be for a plasma track cutter or something with a pendent? Or just not know how to wire there own torches lol
