CD Weld Pins are a type of insulation pins that are applied with welding or equipment. Made of different materials depending on the application, such as Mild steel, Stainless steel, or Aluminum material. They are popularly used as insulation fasteners in combination with self-locking washers or dome cap washers.

• Name: Capacitor Discharge (CD) weld pins, Insulation Pin / stud pin / welding pin / stud welding accessories / weld pins / stud welder pins
• Material: Copper coated/Zinc plated for mild steel. Stainless Steel, Aluminum material, etc.
• Pin diameter: 3.0mm in common, 2mm, 2.7mm, 3mm, 4mm, 5mm, etc.
• Pin length: 20 mm-350mm, length could be made according to your requirements.
• Fixing parts: Speed clips/Washers.
• Application: Marine building system, Power plant, other equipment.

CD Weld Pins are used for attaching insulation to various metals with the use of a CD welder. After the pin is welded in place, the insulation is impaled on the pin and secured with a self-locking washer.

• Length of this style pin should exceed the thickness of the insulation, in order to securely attach the self-locking washer.
• Nail point is standard - available with "blunt end" as special order.

CD Weld Pins are used in various industries including:

• Car manufacturing
• Train Stations
• Industrial building
• Household Adornment
• High stress environments such as off road construction
• Large expansion bridges
• Skyscrapers
• Power plants
• Military defense vehicles
• Equipment in high temperature environments

1. Weld pins in place
2. Install insulation on pins
3. Press washers on pins
4. Bend over the pin or clip off the pins

• Standard pin point, easy for welding
• Pins are soft, easy for bending over
• Self locking washers are safety for installing

• Length of this style pin should exceed the thickness of the insulation, in order to securely attach the self-locking washer.
• Nail point is standard - available with "blunt end" as special order.
• Capacitor Discharge weld pins simplify the permanent attachment of insulation to just about any kind of construction metal surface.
• They can be applied quickly and easily using standard CD or Arc stud welding equipment.
• Weld pins are available in different styles to cover a wide variety of applications.
• Some factors to consider regarding the pin style needed for your job would be the base metal type size and surface condition, and also the welding equipment to be used.

The standard, portable CD system consists of:

• The Controller or (Power Unit) which is plugged into the one-hundred-and-ten-volt outlet.
• The CD Gun with cables is used to command the power unit and deliver weld current, with the Gun also serving as the Pin holder to properly place the pin during welding.
• Then, on the other side of "the circuit" a ground cable and clamping connection is attached to the work-surface to complete our Capacitor Discharge connections.
• And finally, special accessories are used to hold the Pin in the Gun.
