I have a 250EX and like using the foot pedal for tack welds but want to use pulse & slope functions to finish welding up the jigged parts but don't want to swap the 7 pin connector all the time, nor do I want to place a switch on the torch.

If I put a switch in line with the jumper on pin 6&7 on the foot control can I use the pulser/slope functions if disconnect the jumper to fool the welder into thinking the foot pedal is not connected yet use the pedal for the switch without the pot causing any control issues?
