2 INTRODUCTION
The Miggytrac™ B501 is designed for MIG/MAG welding of plates and beams.
The Miggytrac™ B501 is a compact battery driven tractor on which a welding torch can be
fitted. It is equipped with four wheel drive for good traction and a high torque stepper motor
for stable welding speed. The Miggytrac™ is intended for welding with 4-stroke control mode.
As an option there is an easy fit magnet kit. The magnet kit can be attached at the bottom of
the tractor to further stabilize the movement when welding slopes up to 45°.
A battery and a battery charger are not included in the delivery, refer to the "ACCESSORIES"
chapter in this manual.
