Tips on how to Plastic weld using a Plastic Welder

Remove the damaged item for plastic repair from cold and windy conditions.
Pre-clean the damaged areas with warm soapy water or mild solvent de-greaser.
Rough sand, with 80 grit paper the area of repair beyond 2.5 inches of the joint if the area is to be finished with epoxy
adhesive repair compound and color coated.
V- grind with rounded shoulders the damaged area for plastic welding and join parts with foil tape or with our industrial
Plastic Adhesive, Product Number 180, which can also be used in conjunction with our Plastic Primer/Accelerator. If the
plastic is difficult to bond, small holes can be drilled through the shoulders of the parts to be repaired for added adhesion.
Keep the area for repair as warm as possible.
Preheat the plastic welding gun for approximately 15 minutes to desired temperature before starting your plastic welding
process.
Insert your plastic welding rod into the preheated tube and feed your wire in a steady motion, moving your applicator tip
along your joint. After your plastic welding rod has been applied, smooth over your welded area in a circular motion to join
and bed your molten weld into the original substrate. Allow ample time for your weld to cure. Follow the same procedures
on the reverse side of your repair if required or back with fibre reinforcement tape and one of our Rapid Patch epoxy
adhesive repair compounds. If both sides are to be welded, leave a thin space between the two pieces to allow molten weld
to join each other.
You are now ready to finish sand, starting with 150 grit paper, proceeding with either waterbourne solvent or two part
epoxy primers and your finishing color coat if required.
Note: not all plastics are easily primed or color coated. Special preparations are required under these circumstances. Follow
proper paint manufacturers procedures for plastics.
Note: if the plastic welder you choose is not heat controlled, you must take care not to burn your repair.
