A6 Mastertrac A6TF (Single/Twin)

Self-propelled, 4WD, automatic tractor with two different designs:

Single: available with standard or high speed motor

Twin-Arc: with a simple add-on for the extra wire, you can convert an A6 Single Mastertrac into a highly productive automatic Twin-arc welder for fillet and butt welds without the use of an extra machine or power source.
