DENTFIX DF-1 This is the "Original Stud Welding Kit " from SPITZNAGEL sold by Dent Fix Equipment since 1978. Made in Germany, these tools are built rock solid and have to be because we put our family name on it. The DF-1 is the first stud welding system offered in the U.S.A. and it has changed the way car panels are repaired. No longer are destructive holes drilled into the panel in the name of repair. This one kit established our reputation for and continuing goal to provide you the technician with quality equipment and innovative designs. Stud Welders remove dents by welding copper coated steel core pins to any steel panel. Simply slide the pull hammer over pin, twist to tighten and tap or bang out damage. With our 2 pronged grounding ring multiple pins can be welded right next to each other. This will create a very strong pulling tab allowing creases and rocker panels to be repaired. Made in Germany, this time-tested tool has proven to be the best in the industry. The Dent Fix Stud Welder works without drilling or distortion, does spot shrinking and installs wiggle wire. Kit includes Extreme duty Gun; slide hammer, mini puller, 4-finger "Bear Claw" puller, 1000 2.0mm pins, 500 2.6mm pins and a custom carrying case.
