Performance in Production
- The speed control knob sets how fast the rack moves forward, so the operator can slow down for a fine bead or run faster to fill a joint. No-load speed is 0.20 in/sec (5.2 mm/sec).
- The switch runs the gun only while it is held down. Release it and the rack stops, then backs up 0.2 to 0.4 in (5 to 10 mm), which helps stop the bead from running on.
- The unlock button frees the rack so it can move back by hand, which speeds up cartridge changes.
- The built-in 7.4 V, 2 Ah battery charges through the USB-C port, so there is no air line to run and no hand squeezing on repeat 50 mL work.
- The LED charge indicator shows green at full, blue at 3/4, yellow at 1/2, and red at 1/4, so the operator can check the battery before starting a bead.
- The gun is set up for 1:1 only. For 2:1, 4:1, or 10:1 square back cartridges, use the Chem-Set PAK-50 manual gun listed under Related Products.

How Battery-Powered 50 mL Cartridge Dispensing Works
A battery gun pushes the cartridge plungers with a motor-driven rack, so the operator controls the bead with the speed knob and switch instead of squeezing a manual gun. The steps below follow the controls on the Pak-50 electric gun.
- Confirm the cartridge is a 50 mL square back A-System or B-System cartridge that runs at 1:1.
- Charge the gun through the USB-C port and check the LED. Green is full, blue is 3/4, yellow is 1/2, and red is 1/4 and low.
- Hold the unlock button to free the rack, load the cartridge, and fit the mixer nozzle your cartridge calls for.
- Turn the speed control knob low to start, then raise it until the bead is steady for your material.
- Hold the switch to dispense. Release it to stop. The rack backs up 0.2 to 0.4 in (5 to 10 mm) so the bead ends cleanly.
