KÖCO Stud Welding Guns
The CLASSIC series of stud welding guns are technologically advanced high performance tools for drawn arc stud welding. They are designed for comfortable operation and known for their sturdiness and reliability. The range includes guns for every application, matching accessories are available.
The precision technology of KÖCO stud welding guns ensures repeatability and produces first-class welding results, even under difficult operating conditions. An adjustable hydraulic plunge damper is standard in the K 22-D, K 24 and K 26 guns, to damp the stud movement when it is plunged into the welding pool (recommended for welding studs from approx. 14 mm ø).
All guns are compatible with most commercially available stud welding systems.
