Changing Attachments
The kit is supplied with three attachments for the plastic welding tool:
• Standard plastic welding tip (G) — used for general repairs with the stainless steel mesh and for
melting ribbon-type plastic fi ller strips.
• Hot staple attachment (H) — used to apply the supplied 0.6 and 0.8mm staples to stabilise and
reinforce repairs.
• Plastic welding tip fi tted with a fi ller rod feeding tube (I) — the supplied fi ller rods are fed
through the tube so that they melt directly onto the job. Used for deeper cracks that have been
V-ed out to take the fi ller. The attachments are connected to the tool via a twist-lock / bayonet
type fi tting (S in Figure 1). Holding the tool away from you, line up the attachment with the notch
on the housing, push in, and twist to the left to lock in position. Ensure that the attachment is fully
turned to the left and locked in place.
To remove, twist the attachment to the right, then lift off.
The orientation of the attachment can be adjusted by turning the knurled grip (T in Figure 1) to the
required position.
Using the Plastic Welder
With experience, many uses can be found for the plastic welding tool. But fi rst, it is important to
identify the type of plastic that is to be repaired. Look on the back of the panel or component; the
type of plastic PE, ABS, PP or PS, will be clearly marked. Use the correct fi ller rod for the type of
plastic being repaired.
With the hot staple attachment, it is worthwhile practicing on some scrap plastic components to
familiarise yourself with how much heat needs to be applied (length of time control button C is
depressed), to get a staple to a temperature where it will slide into the plastic being repaired, and
to get a feel of how much pressure is required to ensure that you don’t push straight through the
component.

Plastic Welding Repair:
1. Standard plastic welding tip (G) attachment. An example of a repair is outlined below:
Repairing a split or crack in a plastic bumper:
• Using a mini-sander or belt-sander fitted with a 120-180 grit disc, remove paint and primer from
the surrounding area and bring the level of the surface down around the area to be repaired.
Then feather off with a DA sander.
• Fit the standard plastic welding tip (G) to the plastic welding tool.
• If the split goes to the edge of the panel, it is recommended to reinforce with a hot staple inserted
at the top edge of the split. The edge is held straight and flush as the staple is applied.
• If necessary, stainless steel reinforcing mesh (P) can be cut to size. For a split it will be cut to
strips about 12-25 millimetres wide.
