The A2 Tripletrac is the result of years of experience and the latest technology. It is designed to put your welding opera- tion on the right track to increase pro- ductivity and quality. The A2 Tripletrac is superb for internal circumferential weld- ing of large cylindrical objects due to its clever design with a steering wheel. The tractor can be equipped with ESAB’s A2- A6 Process Controller PEK or A2 Weld- ing Controller PEI.

The A2 Tripletrac’s three-wheeled tractor carriage steers with the front wheel. This, combined with the fact that the steering wheel also controls the horizontal slide, ensures easy control of the wire position. This makes the A2 Tripletrac ideal for internal circumferential welding of large cylindrical objects that are rotating on a roller bed, for example pressure vessels and wind towers.

The compact, efficient design makes it easy to move the A2 Tripletrac from one place to another, such as between different welding workpieces. The carriage is equipped with a handle to disengage the gear, so the A2 Tripletrac can easily be pushed to another place.

The heavy-duty feed units secure an even and stable wire feed – a prerequisite for top quality, homogenous welding.

The A2 Tripletrac can be delivered with both the A2-A6 Process Controller PEK and the A2 Welding Controller PEI.

A2 Welding Controller PEI
The control equipment is very easy to use with a minimum of training. The welding parameters are adjusted by turning knobs and the actual para- meters are shown on the digital displays.

With the controller the user can choose between different start methods, direct start or scratch start. The burn-back time is also easily adjustable to optimise the stops for different size of wire.

Programmed precision with ESAB’s A2-A6 Process Controller PEK
The digital electronic control equipment with a digital display makes fast programming and control of all welding parameters possible in different languages.
255 different weld sets can be stored in the controller.

The controller optimises the welding depending on material and consumables to always get perfect arc striking and welding.
