Weld-Ons are manufactured with consistently sharp points to ensure positive contact when welded to sheet metal. Produced from carbon alloy steel, the point of the welding pin is hardened in a unique cold form process. This hardens the points giving them a steel temper, which unlike other welding pins, will not blunt or flatten when applied. The sharper point of contact results in a better weld and creates fewer sparks to ignite adhesives or burn substrates. Weld-Ons are easily applied using any conventional portable or automatic resistance welding unit. Cup style washers are designed to sufficiently depress the insulation surface without tearing it.
Stik-Ons are 14 gauge steel insulation pins which are permanently staked through 2" x 2" galvanized steel base plates. A pressure-sensitive adhesive backing provides a permanent bond between the Stik-Ons and ductwork.
Spot-Ons and companion clips, sold separately, are a convenient and proven method for fastening insulation blanket or board to sheet metal. Spot-Ons are ring shanked pins, made of 14 gauge low carbon steel, annealed and zinc-plated. Apply using any portable or stationary resistance welding unit with hollow magnetic tip. Available in four lengths, Spot-Ons can accommodate up to ½" – 2½" thick insulation.
