The following items have been added to your list


Miggytrac B501 is a compact, universal battery-driven tractor that can easily mechanise your GMAW process and thermal cutting applications where weaving is not required.

Miggytrac's true 4-wheel drive and high-friction wheels guarantee stable movement and operation of the tractor. The carriage follows the weld joint using guide wheels that adjust to allow the unit to drive itself against the workpiece.

Ideal for use with ESAB's GMAW power sources and feeders. A standard ESAB welding torch can quickly attach to the unit.
