The newly developed, extremely robust and durable PH-2L stud welding gun has been especially designed to meet the hardest operating conditions and requirements. This stud welding gun allows you to weld studs and pins up to a maximum of 16 mm in diameter according to the drawn arc and short-cycle drawn arc principle. The automatic length compensation system suitable for differing stud lengths and positioning conditions as well as the oil damping system for controlled plunging of studs with a minimum diameter of 12 mm guarantee high-quality stud welded joints. The oil damping system can be switched on and off.
