GUN SETUP FOR WELDING ALUMINUM STUDS
Figure 2
1.
If gun is not equipped with Tranquil-Arc
®
,
install the 512-241-100 Plunge Dampener Kit
for aluminum stud welding on the Standard
Hand Gun.
Note:
Long length style chuck required with
Tranquil-Arc
®
for aluminum stud welding.
2.
Insert chuck in the chuck adaptor. While
holding the gun by the chuck adapter, lightly
tap the chuck with a hammer until it is seated
and held firmly in the taper of the chuck
adapter (See Figure 2).
Note:
A different Chuck is required for each
stud diameter.
3.
Fasten the Gas Adaptor Foot Assembly (751-
020-000) to the legs with screws and washers
provided. Insert legs into gun body and lock in
place.
Note:
The Gas Adaptor Foot Assembly is a
combination gas adaptor, valve, foot and ferrule
grip. Gas flows only when foot is in the ready
to weld position.
When welding 3/16, 1/4, and 5/16-inch
diameter studs, use the insert grip included with
adaptor (See Figure 2). Remove insert grip
when welding 3/8, 7/16, and ½-inch diameter
studs.
4.
Insert stud in Chuck and ferrule in Gas Adaptor
Foot Assembly.
5.
Loosen screws holding Gas Adaptor Foot
Assembly and adjust adaptor so that stud is
centered in the ferrule. This is important
because improper welds will result if there is
any binding or friction between the stud and
ferrule.
Adjustment of Plunge
1.
Loosen leg set screws and adjust the legs so
that the stud extends 1/8" to 3/16" beyond the
Gas Adaptor Foot Assembly. Measure from
edge of chamfer on stud as shown in Figure 2.
Do not attempt to control weld appearance
by changing the plunge. Inadequate plunge
will result in weld failures.
2.
When stud is so positioned, tighten leg screws
so that the Gas Adaptor Foot Assembly cannot
move.
Note:
It is necessary to adjust plunge when
changing stud lengths.
Adjustment of Lift
Aluminum stud welding requires that the lift be set
at 3/32". See page 3 for adjustment procedure.
