when the trigger is released........does the gas stop immediately? The welder I'm replacing has a delay approx. 3 -5 sec which is costing me a lot of gas ($). It's a 175, and we do a lot of tacking / stitching. We also had trouble with the solenoid not releasing and the trigger on the torch having to be tickled to activate the solenoid. These are the issue we have had.....is the 190 handler going to be ok for us ? Thanks bob Bennett 573 776 5924 (cst)
