CDSTUD

［Application］

When using the CD stud welding system, connect the ground cable to the CD stud welding machine and connect it to the base metal as shown in the figure below.
Depending on the material of the CD stud, a designated gun can be connected and welding can be performed reliably with a simple operation.

Our CD stud are also compatible with CD stud welder from various companies.

Features
●Three types of lamps are used to make work easier.
①Can check the completion of charging by the indicator lamp on the main unit.
②When the pin touches the base material, the lamp lights up.
③When the trigger is activated, the lamp will light up. ●（Green）：Charging complete ●（Yellow）：Pin contact ●（Red）：Trigger activated
●Can check the voltage with the digital meter on the front.
●Can freely adjust the voltage while the power is on.
●Even if the input voltage fluctuates between 90V and 110V, the voltage is stable and the welding quality can be maintained.
●Welding is complete in a very short time of 3 / 1,000 to 6 / 1,000 seconds, so the effect of welding heat on the base metal is small.

The above is a guideline for the welding compatibility between the stud and the base metal. Please perform a confirmation test in advance to see if welding is possible.

Properly welded studs have the welding strength that suits the purpose of fastening, depending on the diameter and material.
