Contact Shrinking - Pro Spot PHS-101 Instruction Manual

6.0 SINGLE-SIDED WELDING

6.8 CONTACT SHRINKING

Dent pullng with washers creates high spots in the metal. Until now, the common
practice would have been to grind the surface, resulting in a lot of sheet metal
thickness. With the Hybrid Spot, use the shrinking tip instead of a grinder to
remove the high spots, leaving a smooth and clean surface that is every bit as
thick and strong as before. Shrinking electrode also acts as a nut adapter (6.4
"Nut Welding"). With this electrode you get two convenient tools in one.

and push the trigger to weld.
