ESAB introduces battery-powered, rail-mounted tractors for mechanised MIG/MAG welding applications
December 20, 2018
ESAB Welding & Cutting Products has introduced a full suite of mechanised welding systems.. including the Railtrac™ B42V (a rail-mounted tractor with a new weaving unit), the Railtrac BV2000 (a rail-mounted tractor for rail hardfacing), the Miggytrac™ B501 (compact, battery-operator tractor) and the Miggytrac™ B501 (compact, battery-operator tractor) and the Miggytrac B5001 (compact, programmable tractor)..
"There are four great reasons to consider mechanised welding for long, and even not-so-long, joints and seams: productivity, consistency, flexibility and ergonomics," says Edward Hansen, Global Director of Product Management, Flexible Automation, ESAB.
Welding tractors increase travel speeds/deposition rates by 100 percent compared to manual welding. They move faster, don't need to stop for repositioning and enable welding with higher parameters and/or larger diameter wires. By making continuous welds, tractors reduce rework associated with start/stop defects. In applications where customers expect uniform weld bead profile and penetration, mechanised tractors deliver consistency without the cost or complexity of automation.
"ESAB tractors feature offer compact, lightweight portability and easy disassembly, making it easy to move the to work site," adds Hansen. "The also reduce operator stress by reducing fume and UV radiation exposure, as well as reduce welding in uncomfortable positions."
The Railtrac™ B42V is a universal rail-mounted tractor for welding or cutting that operates in the flat, horizontal or vertical positions. It features the new W8000 remote weaving unit for make weave welds up to 80mm (0 - 3.14 in.) wide and for weld path tracking. Operators can program weave patterns, travels speeds and control voltage and wire feed speed for five standard programs. Stepper motors for both the drive and weave functions ensure smooth operation and high precision. The Railtrac B42V works with any wire feeder, but connecting it to an ESAB wire feeder enables adjustment of weld parameters and arc start and stop. For added flexibility, the Railtrac can be powered with 42V from the power source or an 18-volt Makita rechargeable battery, which is hot-swappable for continuous operation.
The Railtrac BV2000, also a rail-mounted tractor, can be configured to create the optimal solution for mechanised rail hardfacing applications. Its controls include six standard programs.
The Miggytrac B501 is a compact, battery-operated tractor that embodies affordability and simplicity. Other than clamping a torch in the holder, there is no physical connection between the tractor and the power source. Miggytrac B5001 also works with any wire feeder, but connecting it to an ESAB wire feeder enables adjustment of weld parameters and arc start and stop. A color TFT LCD display with an intuitive, modern interface enables operators adjust multiple functions to improve weld quality and program weld patterns.
"The TFT display separates the B5001 from the competition," says Hansen. "It provides a better user-experience and adds more functionality. For example, users can program a faster intermittent travel speed between stitch welds (up to 170 cm/min) to reduce cycle time. To reduce seam defects at the end of a weld, users can adjust crater fill and back fill functions."
All Miggytracs use stepper motor drives to provide smooth travel at low and high speeds while high-friction wheels guarantee stable movement, even on inclined surfaces up to 45o. They can be powered by 18-volt Makita rechargeable battery, which is hot-swappable for continuous operation. The Miggytrac B5001 can also be powered with 42V from the power source.
