Contact equipment for submerged--arc welding
S For single wire 3.0 -- 4.0 mm. Light duty (D20)
Use the straightener (3), connector (1) D20 with contact tip (2)
(M12 thread).
S Tighten the contact tip (2) with a key in order to ensure
that a good contact is achieved.
S For single wire 1.6 -- 2.5 mm Submerged--arc.
Light duty (D20)
Use the straightener (3), connector (1) D20 with contact
tip ( 2) (M12 thread) and separate fine wire straightener (4)
with guide tube (6).
S Fit the clamp (7) with guide tube (6) in the M12 hole on
the straightener (3). The guide tube (6) should bottom
on the contact tip (2).
S If necessary, cut the guide tube (6) to length so that the
feed roller (5) runs freely.
S Fit the fine wire straightener (4) on the upper side of the
clamp for the straightener (3).
S For single wire 3.0 -- 6.0 mm. Heavy duty (D35)
Use the straightener (3), connector (1) D35 with contact
jaws (2).
S Fit one of the contact jaws with the M5 bolts provided, in
the fixed contact tip (a).
S Fit the other contact jaw in the free half of the two --piece
connector (b) under the bolt (8) and tighten down hard to
ensure that a good contact is achieved between the
contact jaws and the wire.
S For flu x--cored wire 1.6 mm -- 4.0 mm ( D20 and D35) (Accessories)
If contact jaws (D35) are used, the contact jaws must not be tightened too hard
in order that the flux--cored wire is not deformed. Ensure that good contact is
achieved with the wire.
S Adjustment of the wire for tandem welding
S The distance between the first and second wire must not be so great that the
slag gets time to solidify between the wires.
S Ensure that good flux coverage is achieved between the first and second
wires.
