1. Before spot welding the zinc plated steel plate, re-
move the paint from both sides of the flange to be
welded. Apply sealer to the flange after welding.
CAUTION: To prevent eye injury, wear goggles or
safety glasses whenever sanding, cutting or grind-

NOTE: Seal the sanded surfaces thoroughly to pre-
vent rust.

plate is different from ordinary steel plate. When spot
welding, increase the current by 10-20%, or increase
the resistance welding time.
Increase the number of weld spots by 10-20% also.

steel plate are the same as for ordinary steel plate.

welding, wear an approved welding helmet, gloves and
safety shoes.

mote adhesion and prevent blistering.
