Overview

TA3 robotic air-cooled MIG gun feeds through the robot arm (ThruArm) for outstanding precision and reliability in high-volume production. At its core is the LSR+ (low-stress robotic) unicable: unlike conventional unicables, it uses a rotating power connection that reduces torsional stress as the robot moves, while a protective external conduit shields it from harsh welding environments. A re-engineered neck clamp delivers consistent clamping force, and a precision keyway system ensures accurate alignment and quick neck replacement. Additional standard neck options expand your TCP choices and cut the cost and lead time of necks that used to be specials. The TA3 replaces the ThruArm G1 series and works with existing G1 air-cooled necks, power pins, and consumables, with no change to gun part numbers. It’s available as a complete package, from power pin to contact tip, with clutch or solid mount and optional wire brake, air blast, and I.C.E.™ technology.

Ordering rules

Robot codes set the mount: ABB and FANUC are solid mount only; COMAU and OTC Daihen/Nachi are clutch only
Some robots require specific power pins: FANUC iD (F11–F16) and Kawasaki BA013 (W46, W47) need Miller® or Lincoln®; Panasonic TM (P37, P39, P41) need Miller® or Panasonic®; P40 and W45 need Miller®
I.C.E.™ necks: FANUC and ABB only, and no air blast on FANUC with I.C.E.
Chrome zirconium tips: 0.030″–0.045″ only; HDP tips: 0.035″–0.052″ only
Fronius® pin: contact Tregaskiss tech support with the feeder model
No consumables: use 0 for nozzle, contact tip, and wire size

Tool Center Point

Repeatable TCP, every neck change.
TA3 robotic MIG guns are engineered to hold an accurate, repeatable tool center point. A precision keyway system aligns the neck the same way every time, and a re-engineered neck clamp delivers consistent clamping force. With a wide range of standard necks, you can match the TCP and working envelope to your application without waiting on special-order parts.

Ranges vary by robot make and model. Adding wire brake increases TCP by approximately 36–37 mm on most robots. *Available as a separately ordered neck. See the spec sheet for exact TCP values by robot model.

Keep TCP on target

Precision keyway system: accurate neck alignment for quick, repeatable replacement
Re-engineered neck clamp: consistent clamping force for stable positioning
AccuLock™ R consumables: in most cases, upgrade your tip and diffuser with no impact to TCP
Neck checking fixture (G-405CA): verify and re-master TCP, and realign the neck after a collision
