HOW TO WELD PLASTIC WITH THE LEISTER #100.726 TRIAC S ELECTRIC WELDING TOOL

Plastic components that would be expensive to renew can be repaired by welding with the LEISTER 100.726 ELECTRIC WELDING TOOL.  Almost every motor vehicle today has components manufactured from a variety of plastics.  Bumpers, grilles, light surrounds and even complete body panels enable designers to enhance aerodynamic styling and cosmetic appeal while retaining impact resistance and eliminating corrosion.

Plastic offers the structural strength of steel by virtue of its greater elasticity.  Minor impacts that could deform steel beyond repair can be absorbed by plastic.  Where damage is incurred it is capable of repair by welding with no loss of component strength. Cracks, splits, warping and even the loss of material can be remedied with the aid of the LEISTER TRIAC hot air welding equipment.  Where a steel component with equivalent damage would be renewed at some cost the repair of the plastic part can save time and expense, particularly when winter accidents periods make great demands of the repairer's parts stock.

Welding plastic does not produce fumes when the correct procedure is followed.   A plastic component can be quickly restored to an 'as new' condition without the need for fillers or special treatments.  The combination of welding and recommended paint procedures will show no trace of a repair that should last the life of the vehicle.

The majority of plastics employed in vehicle manufacturing are thermoplastics. Heated until they soften, they can be molded or welded. There are different types of thermoplastics, each having a specified temperature for welding operations.  Some vehicle manufacturers mark plastic components with material identification codes. ABS and PP/EPDM are easily welded.

Following the simple preparatory steps will ensure a successful repair. Plastic components can be repaired from the front or rear according to ease of access. Reinforcement welds can be used across the rear of a front repair to restore strength to areas designed to withstand impact. The photographs demonstrate a repair from the front of a component.
