The drawn arc stud welding gun GD 19 is designed for welding shear connectors up to a diameter of 19 mm. The gun is equipped with a very high-grade outside welding cable. The generous dimensioning (cable cross section: 70 mm²) enables extremely fast welding sequences and guarantees a long life time of the gun.
With the adjustable lift (adjustment range: 0-4 mm) and the newly developed adjustable hydraulic piston damper the new GD 19 can be perfectly set up for each welding task. The new 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.
Highlight of the new gun is the integrated travel measuring system (optional). Using this the lift adjustment couldn`t be easier. Moreover, it enables a quality monitoring by measuring and recording of stud protrusion before the weld as well as stud travel (lift, immersion depth, immersion speed and short-circuit time) during the weld.

• adjustable lift (raster 0,3 mm) with very large adjustment range (0-4 mm)
