- Air-operated, lube-free cylinder eliminates oil mist in the shop environment.
- Electrode force is adjustable via an integrated filter/regulator combination.
- Reduce shop noise with integrated speed control valves, shock absorber for end of cylinder stroke, and air exhaust mufflers.
- Two-stage electronic foot switch initiation (1st stage closes tips without welding, 2nd stage initiates weld schedule.)
- Pre-wired to accept a second footswitch (Option 72977).
- A second footswitch allows for immediate recall of a second weld time / current setting. This is helpful when different settings are required on the same workpiece.
- PINCH POINT SAFETY OPTION: WSI-supplied TECNA Rocker Arm Welders are available with UNITROL Soft Touch Safety for pinch point protection.
