0461233881 - ESAB A2 Multitrac SAW Tractor with PEK Controller and Twin Wire Kit

Mastering Heavy Plate Welding with the A2 Multitrac

For professional welders and fabricators tackling long, continuous joints on heavy plate, the ESAB A2 Multitrac SAW Twin PEK is a game-changer. This automatic welding tractor takes the physical strain out of long welds while delivering a level of consistency that is hard to match manually. The "Twin" in the name refers to the twin-wire submerged arc configuration. Instead of feeding a single wire, this head feeds two smaller wires simultaneously into the same weld pool. This creates a higher current density and allows you to lay down metal much faster, drastically cutting down arc-on time for thick sections.

Controlling this beast is the ESAB PEK controller, known for its user-friendly interface and clear digital display. You don't need to be a computer programmer to set it up; it's designed with the welder in mind. You can easily adjust your amps, volts, and travel speed right from the tractor. The PEK also allows you to save your favorite settings, so if you're switching between different joint types, you can recall your parameters instantly without recalibrating. This feature is a massive time-saver on the shop floor when moving between different assemblies.

One of the standout features of the A2 Multitrac is its mobility. Unlike massive column and boom setups, this tractor rides right on the workpiece (or a track). Its four-wheel drive system grips the plate securely, ensuring smooth movement. This is critical because any stutter in travel speed shows up immediately in a sub-arc weld. The steering handle allows for easy guidance, or it can be set to follow a guide rail for perfectly straight runs, ensuring your bead lands exactly where it needs to be.

Maintenance and setup are also straightforward. The wire feed mechanism is robust and accessible, making spool changes and drive roll adjustments quick. The flux hopper is positioned for optimal flow, ensuring the arc stays submerged without constant manual intervention. Whether you are welding bridge girders, ship decks, or pressure vessels, the A2 Multitrac SAW Twin PEK gives you the power of automation in a portable, manageable package, letting you focus on the quality of the weld rather than the fatigue of the process.
