How to weld using the USC Mini-Weld Model 7 Plastic Welder:
Clean the repair area with a good quality plastic cleaner and wipe with a clean cloth in a single direction
Bring out the DA sander with the correct sandpaper and work to remove paint, primer until bare plastic is exposed
Work on both the sides of the plastic and dust away with compressed air
Clean the surface again with the plastic cleaner and apply aluminum body tape on one side while you weld on the other. The aluminum tapes are a preferred choice as they can withstand heat from the welder
Use the teardrop shaped airless welding tip to grind along the crack line and round away the sharp edges before preparing to weld
Use the appropriate rod for the repair and set the temperature in your welder (approximately 830 °F)
When the welder realizes operating temperature, it is time to heat the tip of the rod with the welder and allow the rod to melt the base material
Continue the process till the crack is filled up completely
Follow the same process on the other side of the plastic
Grind away excess plastic with the tear drop welding tip
Abrade the surface with a DA Sander before you begin the process of retouching any further
