Features/Benefits

* Used to provide a very uniform and high quality weld deposit for building up worn or damaged bores (adds material to bores using the GMAW (MIG) welding process).

* Unit is fully automatic and microprocessor controlled * Can be set up and used in any position.

* Uses solid or flux core wire of 0.76 to 1.14 mm (.030 to .045 in) diameter.

* Repair bores from 25.4 to 482.6 mm (1.00 to 19.00 in) with standard units.

* Larger bore repair up to 685.8 mm (27.00 in) can be done using optional parts.

* Each welding group includes:

Rotary welder

Wire feeder

Control cables

Adjustable base

Control box

Wire feed conduit, 1524 mm (5 ft)

Welding torches

Torch extensions

Spare torch tip diffusers

Setup tools and carrying case

Tool operating manual

Weld-calc time and material estimating program.

* Auto-skip units can be adjusted so weld is applied to only part of a bore (for example, to bring a bore worn oval back to a round condition or prevent filling a keyway with weld).

* Optional components for the welder include: torches for 457.2 to 685.8 mm (18.00 to 27.00 in) bores, hand held MIG gun, torch extension support, torch counter balance, wire feed conduit [914 mm (3 ft.) long], 90 degree power connector.

* Call Caterpillar Service Technology's technical experts, to answer any other welding related questions.
