AS Schoeler Bolte Pro-D 2200

The PRO-D 2200 basic is designed for drawn arc and short cycle stud welding. The basic version of the PRO-D 2200 is distinguished by its ease of use and its robust construction.
Welding current and time can be continuously adjusted by the solid rotary knob with a built-in push button, the adjusted values are shown on a big display. The proven constant current regulation and microprocessor control of the PRO-D series ensure in connection with the high performance of the unit optimum welding results and repeatability.
Optionally, the unit can be equipped with a shielding gas module for welding with shielding gas for weld pool backing and a weld counter.
