Resistance welding of automotive parts calls out normally for different welding schedules for different metal combinations. For robotic welding lines, the call for different welding schedules is simple. Robots simply select the desired weld schedule by spot number or by schedule number. For manual operations however, it is difficult for human operator to reliably select more than one single schedule.

As a result of this, welding lines for manual operations tend to spread out because they limit the number of different schedules for each welding gun. So instead of conveniently processing a multitude of different welds on a few welding guns, the line is populated with multitudes of welding guns which are restricted to weld limited spot welds.

Resistive Adaptive Feedback Technology (RAFT) makes it possible for an operator to activate a weld gun with a single trigger and have the welding control to automatically select the welding schedule to make the weld.
