The compact stud welding gun PHM-1A is designed for capacitor discharge stud welding (gap method). It guarantees optimum welding results and repeatability and is very easy to use. The PHM-1A stands out through its robust construction and high reliability. Its ergonomic design and low weight assure tireless working.
Optionally, the PHM-1A is available 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 protrusion before the weld as well as stud travel (lift, immersion depth, immersion speed and short-circuit time) during the weld.
