Overview

The CA3 robotic air-cooled MIG gun is designed for high-volume production, combining the best features of the G1 and G2 Series platforms with improved unicable technology for longer service life. Rated at 350 amps with a 100% duty cycle on mixed gases, it’s engineered for precision, repeatability, and minimal downtime. A replaceable unicable makes repairs faster and less costly, while a cable guide reduces stress on the connection as the robot articulates. A re-engineered neck clamp delivers consistent clamping force, and a wide range of standard necks and mounting arms expands your tool center point options and working envelope. Choose clutch or solid mount, add wire brake, air blast, or I.C.E.™ technology, and run TOUGH LOCK® or AccuLock™ R consumables.

Ordering rules

Nozzle codes D and G mean different parts depending on whether the tip code is slip-on (A–C) or thread-on (D–F)
Solid mount (2): no control cable, so use 0
E-Z Feed™ liners: 6′ cables or shorter only, and not with wire brake
Chrome zirconium tips: 0.035″, 1.0 mm, and 0.045″ only; HDP tips: 0.035″–0.052″ only
No consumables: use 0 for tip + diffuser, nozzle, and wire size

Mounting disc, arm, and gun mount are ordered separately (Steps 2–4). Cobot BAS arms don’t use a gun mount.

Step 2: Insulating/Transition Disc
Choose the disc that matches your robot or cobot model (59D and 59DT series).
See spec sheet for the full robot-to-disc list.
