Stud Welding Gun · Tip Ignition
Contact-M
Contact welding gun with integrated position measurement system
Hand-held welding gun for capacitor discharge stud welding with tip ignition using the contact method. The integrated position measurement system records relevant motion and position parameters and displays them on compatible CDP-M power units.
Product Benefits
Precise Displacement Measurement for Reproducible Welding Processes
The Contact-M combines the compact design of a manual contact welding gun with digital monitoring of mechanical welding parameters.
Integrated Positioning System
Measurement of bolt protrusion, lift, stroke, and piston speed.
Reproducible results
The travel parameters can be read and checked on the display of the connected power unit.
Ergonomic Handling
The tool's design ensures a secure grip and reduces fatigue during manual applications.
Rugged industrial enclosure
The housing, made of glass-fiber-reinforced thermoplastic , is designed for industrial use.
Large cable cross-section
The 6.5-meter-long welding power cable with a 25 mm² cross-sectional area reduces line losses even during repeated welding operations.
Extensive range of accessories
A variety of mounts, feet, and positioning solutions allow for adaptation to different applications.
Contact-M Position Measurement
Directly Measure and Monitor Mechanical Parameters
The integrated position-measuring system records the movement of the welding stud . When used in conjunction with a compatible CDP-M power unit, the relevant values are displayed on the screen . Process reliability can be further enhanced with the optional electrical process control system.
Welding Processes
Spark Ignition in the Contact Method
The Contact-M is designed for capacitor-discharge stud welding using the contact method. In this process, the welding stud is placed on the workpiece with its ignition tip before triggering.
A Quick Process for Thin Sheets
When the trigger is pulled, the energy stored in the capacitors is released. The ignition tip melts and creates an electric arc. The end of the bolt and the surface of the workpiece are melted, and then the bolt is guided into the molten pool by spring pressure.

The welding stud is secured in the stud holder and positioned on the workpiece with its ignition tip.
Ignite an electric arc
The energy stored in the capacitor is released. The electrode tip melts, and an electric arc is formed.
Dip the bolts
The spring pressure pushes the bolt into the molten metal. The bolt and the base material solidify into a single unit.
