All ModelsWarranty: G
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 welderWire feederControl cablesAdjustable baseControl boxWire feed conduit, 1524 mm (5 ft)Welding torchesTorch extensionsSpare torch tip diffusersSetup tools and carrying caseTool operating manualWeld-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.Specifications/Technical Information
