BTH BOLTE Drawn Arc Stud Welding Guns GD-25
Welding Shear Connectors With Large Diameters
The new drawn arc stud welding gun GD 25 is designed for welding
shear connectors with large diameters (22 and 25 mm).The ample-dimensioned adjustable lift (adjustment range: 0-6 mm)
ensures in combination with the adjustable hydraulic piston damper
optimum welding results in this diameter field. Of course, the new
guns are suitable for welding through metal deck.
The gun also features a piston with linear ball track, an automatic
length compensation system for different stud lengths and surface
conditions as well as a robust, impact resistant housing for the
hard work on the construction site.
The high-grade outside welding cable (cable cross section 120 mm²)
accommodates the high welding currents that are necessary for large
stud diameters.
Optionally, the new guns can be equipped with integrated travel
measuring system. Using this the lift adjustment couldn`t be
easier. Moreover, it enables a quality monitoring by measuring and
recording of stud travel (lift, piston runtime, immersion depth)
for each weld.
