The Shark Industries Mini Plastic Hybrid Tack Welder, No. 17042, repairs plastic parts on bumpers, motorcycles, snowmobiles, trucks and more. The unit quickly reinforces the repair or tear with a metal staple that is embedded into the cracked or broken area. The patented ironing tool smooths the plastic and seals in the metal staples after the repair has been made. The included mesh 1' by 1' metal square can be cut and used for repairing holes. The unit, which is smaller and less expensive than the company's Pro-Tack Plasitc Welder, is capable of doing soldering on some applications.
