FAQ

Frequently asked questions
about the CDP-66M

Which stud diameters can the CDP-66M weld?

The CDP-66M is designed for steel and stainless steel welding studs in the M3 to M8 range. Non-heat-treatable aluminium alloys can be processed up to M6, depending on the material and application.

Which welding guns are compatible?

Compatible models include CONTACT, CONTACT-M, GAP and GAP-M.

What is the difference between displacement measurement and process monitoring?

Digital displacement measurement records mechanical parameters such as stud protrusion, lift, plunge and speed and can be used without optional process monitoring. Process monitoring covers both mechanical and electrical values and compares actual values with setpoints. If a deviation falls outside the tolerance, the unit displays an error message.

Which materials can be welded?

Suitable materials are steel and stainless steel, zinc-coated sheets up to 15 µm and, depending on the material and application, non-heat-treatable aluminium alloys up to M6.

How fast is the welding rate?

The CDP-66M achieves a welding rate of up to 20 studs per minute in continuous operation.
