4.4 Contact equipment for submerged-arc welding
For single wire 3.0 - 6.0 mm. Heavy duty (D35)
S Use the straightener ( 3 ), connector ( 1 ) D35 with
contact jaws ( 2 ).
S Assemble one contact jaw with the M5 bolts provided,
in the fixed contact tip (
a ).
S Assemble 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.
For flux-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 down to
hard in order to ensure that the flux-cored wire is not distorted.
S
Ensure that good contact is achieved with the wire.
Adjustment of the wire for tandem welding
The distance between the first and second wires must not be so great that the
slag has time to solidify between the wires.
S Ensure that good flux coverage is achieved between the first and second
wires.
4.5 Refilling with flux powder
1. Close the flux valve ( 1 ) on the flux hopper.
2. Remove the cyclone on the flux recovery unit, if fitted.
3. Fill with flux powder.
NOTE! The flux powder shall be dry.
4. Position the flux tube so that it does not become
kinked.
5. Adjust the height of the flux nozzle above the weld so
that the correct amount of flux is delivered.
Flux coverage should be sufficient so that penetration
of the arc does not occur.
