The Capstan's small size and light weight (less than 5-1/2 lbs. without torch - less than 8 lbs. with 400 amp water cooled torch) allows the wire feeder to be placed directly on the automated fixture or robot wrist, thus eliminating the wire guide liners normally associated with conventional wire drive systems. The Capstan also provides an increase in wire drive contact area by wrapping the wire around the wire drive wheel. This wire drive method has three major benefits:

Plastic deforms the filler wire, virtually eliminating existing wire cast.

Increased drive force eliminates wire slip, flattening and damage to wire surface.
Integral wire straightener on the discharge side of the feeder allows the Wire Drive to precisely locate the filler wire independent of wire cast.

The WF-100 produces a slip free positive driving force to the filler wire without damaging the wire surface and provides exceptional feeding of the "soft" wires such as aluminum and copper.
