Together with simple and practical operation, the newly developed PH-3N stud welding gun with magnet coil offers a maximum of technical performance advantages for producing high-quality stud welded joints in the radial-symmetric magnetic field. Further advantages are the welding guns ergonomic and slim shape as well as its low weight and exemplary design. In continuous application, the PH-3N stud welding gun allows fatigue-proof welding of studs and pins with a maximum diameter of up to 12 mm using shielding gas as auxiliary aid.
