CA 08 with centering tube PPR-2/CD - Stud Welding Gun

The CA 08 PPR-2/CD stud welding gun combines a compact design with a dedicated centering tube for controlled placement of welding elements. It is particularly suited to thin sheets from 0.5 mm, insulation pins with flange and ignition tip, and CD stud welding applications where consistent positioning and access in confined areas are important.

FAQs

The PPR-2/CD configuration is useful when controlled centering of the welding element is important. It is particularly relevant to insulation pin welding and thin-sheet CD applications where consistent positioning supports repeatable results.

This configuration is specifically identified for insulation pins with a flange and ignition tip. The centering arrangement helps position these welding elements consistently, making the gun suitable for insulation-related fastening applications.

Yes. It is especially suitable for metal sheets from 0.5 mm. Welding performance still depends on the stud, material, welding unit, energy settings, and surface condition used for the specific application.

The PPR-2/CD centering tube helps guide the welding element into the intended position before the welding cycle. This is particularly useful where accurate placement matters more than simply accessing the welding location.

Yes. The gun can accommodate any type or shape of welding element when the appropriate special chuck is used. Standard capability covers M3–M8 and #4–5/16", with larger sizes requiring special equipment.

The PPR-2/CD configuration is listed for use with the CDi-1502, CDi-2302, CDi-3102, CDMi-2402, and CDMi-3202. The correct welder depends on the required stud diameter and welding application.

Yes. The CA 08 measures only 190 × 40 × 140 mm without its cable, giving it a compact profile for restricted-space welding where positioning a larger stud welding gun can be difficult.
