DuroDyne Resistance Welding Equipment Beveled Head 3/8" Quilting Weld Pins For HVAC

Cup Head: Reduces jams and machinery down time while preserving the insulation. Contact Head: Oversized head increases the welding surface, resulting in a reduction in misfires and superior strength.

Point: Forged diamond point for strength and weld consistency. Shaft: High tempered shaft for strength and consistency.

Each Quilting Weld Pins , Cup Head Pin is precisely formed to provide optimum electrical resistance and each cap and shank assembly is securely

swaged so that pins ill feed without jamming, even in older welders. The result is continuous production without the expense of clearing track jams or

refastening where other pins could fail.

What Quilting Weld Pins , Cup Head Pin 

PowerPoint Weld pins permanently attach insulation to galvanized steel in the fabrication of ductwork. PowerPoint Weld pins withstand a tensile pull

of at least 120 pounds in sheet metal and can be used in conjunction with adhesives on any galvanized sheet metal with lock forming qualities of 26

gauge and heavier.

Composition and Materials

The fastener head, shank and point are manufactured from a special carbon alloy steel. A 1" diameter retaining cap fabricated from cold rolled steel

is mechanically affixed to the driven end of the fastener.

Industry Standards

PowerPoint Weld pins meet and exceed the latest SMACNA (Sheet Metal and Air Conditioning Contractors National Association) standards, published

in their HVAC DUCT CONSTRUCTION STANDARDS 1995, for low and high velocity ductwork. They are used by leading air-conditioning, sheet metal

and mechanical contractors for ductwork in commercial buildings.

Technical Data

Corrosion Resistance
PowerPoint Weld pins are plated with .0002" to .0003" of zinc and receive a final chromate dip. This plating exceeds

current SMACNA standards for corrosion resistance.

Retaining Cap

The beveled edge retaining cap is sufficient in size and design to depress the surface of the insulation without tearing

or cutting it. The cap does not protrude into the air stream to create noise or interfere with air movement in the duct.

Temperature Range

PowerPoint Weld pins function properly over normally accepted operating range of temperatures of 32 degrees F to 250 degrees F and are not adversely

affected at temperatures of 0 degrees F to 550 degrees F.
