0449100883 - ESAB A2 Multitrac Tractor Base for PEK

Automate Your Welding with the ESAB A2T Base

For professional welders and fabricators moving into automation, the ESAB A2T Carriage Base is the workhorse that keeps your production moving. This is the mobile foundation of the legendary A2 Multitrac system, a portable welding tractor known worldwide for its reliability in Submerged Arc (SAW) and MIG/MAG (GMAW) applications. Whether you are welding long beams, ship decks, or large storage tanks, this carriage base provides the steady, controlled movement required to lay down consistent, high-quality beads that manual welding simply cannot match.

The "PEK" designation indicates that this base is ready to pair with ESAB's advanced PEK process controller. This combination gives you digital precision over your travel speed and welding parameters. The carriage itself features a rugged 4-wheel drive system. This isn't just about moving forward; it's about traction and stability. The four-wheel design ensures that the tractor maintains a constant speed even if the surface is slightly uneven or if the cables drag, preventing the start-stop inconsistencies that lead to weld defects. It is compact enough to be carried by one person, making it easy to move from one joint to the next.

Investing in the A2T Base allows you to leverage the full versatility of the Multitrac system. You can set it up for single-wire SAW for deep penetration, twin-wire for high deposition, or switch it over to MIG/MAG for structural work. The base is designed to be tough; it withstands the heat, flux dust, and rough handling of a shipyard or structural steel shop. It’s not just a machine part; it’s a productivity multiplier that turns long, tedious welds into a push-button operation.

Why Choose the A2T Base?

• Steady Travel: The 4WD system eliminates slipping, ensuring the heat input remains constant throughout the weld length.
• Versatile Application: Perfect for fillet welds, butt welds, and even internal circumferential welding on large vessels.
• Built to Last: Heavy-duty construction protects the internal drive components from industrial grime and impact.
