2 – Installation
Install the optional pneumatic breakaway
 Installing the torch breakaway kit on the lifter assembly also requires using parts of the torch mounting block kit of the
proper diameter.
 The maximum inlet pressure of the pressure regulator is 10.2 bar (150 psi). Typically, the maximum inlet pressure
should be set at 6.9 bar (100 psi).
 The routing of the leads, stall force, IHS speed, and acceleration or deceleration movements can affect the pressure
setting required to achieve reliable operation.
 If air pressure is removed, the breakaway must be manually repositioned when air is applied. The breakaway will not
rest in its position when air pressure is lost.
