0457357882 - Miggytrac B501 Battery Powered Welding Carriage

Take the Strain Out of Long Welds

As a welder, you know that long, continuous fillet or butt welds are physically demanding. Maintaining a steady hand and constant travel speed for feet at a time takes a toll on your back, arms, and focus. The ESAB Miggytrac B501 is built to be your helping hand. This compact, battery-powered welding tractor attaches directly to the steel plate using a powerful magnetic base and carries your MIG gun for you. You simply set the speed, clamp your torch in the holder, and guide the unit—letting the tractor do the heavy lifting of moving the arc.

The B501 is incredibly easy to set up. It features a true 4-wheel drive system with high-friction wheels that grip the metal securely, ensuring smooth movement even if the surface isn't perfectly clean. The stepper motor provides precise speed control, which you can adjust on the fly to dial in the perfect puddle. Because it runs on a standard 18V battery, you don't have to worry about finding a power outlet or dragging an extra extension cord across the shop floor. It's ready to go wherever you are, whether that's on a bench or out on a large structural beam.

The universal torch holder is designed to grab onto almost any standard MIG gun neck, so you can use it with the equipment you already have. It also allows for easy adjustment of the torch angle and position relative to the joint. If you are welding vertically or on an incline, the strong magnets keep the tractor planted firmly. When you reach the end of a weld, the quick-release mechanism lets you detach and reposition the unit in seconds. It’s the perfect tool for making your day easier and your welds look like they were done by a robot.
