7.5 ANNUALLY:
7.5.1 Remove the movable headpiece and check condition of slide
shafts. Wash slide shafts with low residue cleaner,
lightly oil and replace headpiece.
7.5.2 Check condition of headpiece castings. If worn or broken,
replace with new headpiece. If welder is used in an area
where there are corrosive fumes, clean off all oxides and
paint where possible.
7.6 WELDING DIE INFORMATION
Description:
Welding dies – Lower conducting electrode and clamp jaw.
Welding clamp fingers – Upper clamping member.
WELDING DIES IN POOR CONDITION ARE THE MAIN CAUSES OF BAD
WELDS.
7.6.0 CARE OF DIE SETS
7.6.1 Use a Brass or fiber blade to remove particles of flashings
that build-up on die sets. Excessive flash build-up causes
die burns on material and shorting of die sets.
7.6.2 Do not attempt to clamp material that is not suited for
welder into die sets. Undersize materials will slip and
burn die grooves, oversized materials will overstress
clamping parts.
7.6.3 Do not use welding die sets for a vise. These parts will
not withstand the mechanical abuse.
7.6.4 Whenever welding dies are replaces, clean bottoms of dies
and corresponding die seats to a bright and clean condition
before bolting them tightly into place. An oxidized
surface will insulate
the welding dies and reduce effective welding voltage.
7.6.5 Welding die sets will wear with use and must be changed
occasionally for good welding results. Keep and adequate
supply of replacement parts available. Wire and rod
slippage is a problem caused by poor die sets and a major
cause of wire breaks.
