0461235890 - ESAB A6 Mastertrac Automatic SAW Tractor with PEK Control

The Workhorse for Long Seams

When you have miles of welding to do on thick plate, the ESAB A6 Mastertrac SAW PEK is the machine you want on the track. This isn't just a welder; it's a heavy-duty, self-propelled tractor that takes the physical strain out of long-run submerged arc welding. Whether you are splicing beams, welding deck plates, or fabricating large tanks, the Mastertrac is designed to keep moving and keep depositing metal at high rates, hour after hour. Its robust four-wheel drive system grips the plate firmly, ensuring smooth travel even when the workpiece heats up, preventing the stuttering that can lead to weld defects.

The included PEK controller is a game-changer for setup and operation. Instead of fiddling with analog dials and guessing your settings, the PEK gives you a digital interface where you can dial in your exact amps, volts, and travel speed. Once you have a procedure dialed in, you can save it to memory. Next time you run that job, just recall the program and hit start. This consistency is vital when X-ray quality welds are required. The controller also provides feedback, so you know exactly what the arc is doing at all times.

Flexibility is another key strength of the A6 Mastertrac. It can be configured for single wire, twin wire, or even tandem welding if you need to push deposition rates even higher. The flux recovery system (often paired with this unit) keeps your work area clean and saves money on consumables. The manual slides are sturdy and easy to adjust even with gloved hands, allowing you to fine-tune the torch alignment on the fly. For professional welders in heavy industry, the A6 Mastertrac is the reliable partner that turns massive fabrication jobs into manageable, efficient tasks.
