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
