straightener (4) with two guide tubes (6). F or twin wires < 1.6

mm, a guide spiral, inserted into each guide tube, is used.

S Assemble the twin adapter (9) for M6 contact tips (2) with

the M5 bolts in the fixed half of the two--piece connector

(1).

S Assemble the clamp (7) with guide tube (6) in the M12

hole on the standard straightener (3). The guide tube

should bottom on the twin adapter (9) for the contact tip

(2).

S Tighten the contact tip (2) with a key to ensure that a good

contact is achieved.

S If necessary, cut the guide tube (6) to length so that the

feed roller ( 5) runs freely.

S Adjustment of the wires for Twin--arc welding:

S Position the wires in the joint so as to achieve optimal weld quality by

rotating the connector. The two wires can be rotated so that they are

positioned one after the other along the line of the joint, or in any position

up to 90¡ across the joint, i.e. one wire on each side of the joint.

Contact equip ment for MIG/MAG welding.

S For single wire 1.6 -- 2.5 mm (D35)

Use the straightener (3), connector (1) D35 with contact

tip ( 2) (M10 thread).

S Tighten the contact tip (2) with a key to ensure that a

good contact is achieved.

S Assemble the clamp (7) with guide tube (6) in the M12

hole on the standard 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 For single wire < 1.6 mm (D35)

Use the straightener (3), connector (1) D35 with contact tip

(2) (M12 thread), fine wire straightener (4) with guide tube

(6) and guide spiral, which is inserted in the guide tube (6).

S Assemble the clamp (7) with guide tube (6) in the M12

hole on the standard 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 Assemble the fine wire straightener (4) on the upper side

of the clamp for the straightener (3).

S Connect the cooling water and gas (MIG/MAG welding).

4.3 Refilling with flux powder (submerged--arc welding)

S Close the flux valve on the flux hopper.

S Remove the cyclone on the flux r ecovery unit, if fitted.

S Fill with flux powder. NOTE! T he flux powder must be dry. Where possible

avoid using agglomerating flux powder outdoors and in damp environments.

S Position the flux tube so that it does not become kinked.

S 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.

5 MAINTENANCE

5.1 General

NB! Before doing any kind of maintenance work, make sure the mains is

disconnected.

For the maintenance of the A2--A6 Process Controller (PEH), see the instruction

manual.

5.2 Daily

S Clean flux and dirt off moving parts of the welding machine.

S Check that the contact tip and all electrical cables are connected.

S Check that all bolted joints are tight and that guides and drive rollers are not

worn or damaged.

S Check the brake hub braking torque. It should not be so low, that the wire reel

continues to rotate when wire feed is stopped and it should not be so great that

the feed rollers slip. As a guide, the braking torque for a 30 kg wire reel should

be 1,5 Nm.

Adjusting the braking torque:

S Turn the red handle to the locked

position.

S Insert a screwdriver into the

springs in the hub.

Turn the springs clockwise to

reduce the braking torque

Turn the springs anticlockwise to increase the braking torque.

NB: Turn both springs through the same amount.

5.3 Regularly

S Check the wire feed motor brushes

once every three months.

Replace when they are worn

downto6mm.

S Eximine the slides and lubricate if

they bind.

S Inspect the wire guides, drive

rollers and contact tip on the wire

feed unit. Replace any worn or damaged

components, (see spare parts list on page 215).

S If the carriage travel becomes

jerky, check that hte chain is correctly tensioned. Tension the chain if necessary.

S To tension the chain undo the nut (*1) and turn the cam, then tighten the nut.
