FEATURES
The FWS-3500 is a self-standing heavy-duty welder capable of welding a variety of medium to large
Bands. All controls are conveniently mounted and easy to operate. A four stage upset cylinder provides a
Variable forging force adjustable through a precision pressure regulator and selector valve. A solid state
300 amp weld / anneal control provides precise control of weld and anneal current. It’s two-stage
annealing cycle, and ease of adjustment, allows precise “on the fly” adjustability. This handy feature is a
must for proper annealing. The air assisted parabolic flashing cam starts slowly, and then accelerates to
reach maximum speed at the weld’s completion to produce strong and uniform welds. The special cam
drive system provides smooth and constant cycling with upset pressures as low as 500 lbs. A Quick-
change link pin system provides a three-position jaw spacing positions change (internal) to permit a fast,
easy adjustment for different blade widths. Three sets of back-up alignment sets are included. A circular
set for most tooth forms and two rectangular sets for multi-height and other course tooth forms. A 1-1/2” /
38.1 mm main shaft and linear ball bushings provide smooth stable operation and positive blade alignment.
Manual pre-clamp with a dual stage air / hydraulic assist deliverer’s positive blade clamping up to 12,000
Lbs. along with easy heat pattern control. Other features include semi-automatic platen advance and
retract, integral welder stand and blade hanging rack, built in flash timer and an automatic electric shut
