3 INSTALLATION

3.1 General

The installation must be executed by a professional.

WARNING

Rotating parts can cause injury, take great care.

3.2 Mounting

3.2.1 Wire drum (Accessories)

Wire drum (1) is mounted on the brake hub (2).

S Check that the carrier (3) is pointing upwards.

NOTE! The maximum angle for the wire bobbin is 25°.At extreme angles, wear will occur on the brake hublocking mechanism and the wire bobbin will slide offthe brake hub.

IMPORTANT!To prevent the reel sliding off the hub: Lock the reel in placeby turning the red knob as shown on the warning label atta-ched next to the hub.

3.3 Adjusting the brake hub

The brake hub is adjusted when delivered, if readjustmentis required, follow the instructions below. Adjust the brakehub so that wire is slightly slack when wire feed stops.

S Adjusting the braking torque:

S Turn the red handle to the lockedposition.

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.

4 OPERATION

4.1 General

Caution:Have you read and understood the safety information ?You must not operate the machine beforehand !

General safety regulations for the handling of the equipment can be found onpage 65. Read through before you start using the equipment!

S Select electrode type and flux powder or shielding gas so that the weld materialis as close as possible to the analysis of the base metal.

S Select electrode size and welding data in accordance with the valuesrecommended by the welding materials supplier.

S Thorough preparation of the weld surfaces is necessary to achieve a good weld.NOTE! The width of the weld joint gap must be uniform.

S To minimise the risk of heat crack formation, the width of the weld must begreater than the penetration depth.

S Always carry out a test weld with the same joint type and sheet thickness as theproduction work piece.

S For control and adjustment of the automatic welding machine and welding powersupply, see the instruction manual for the A2--A6 Process Controller (PEH).

4.2 Loading the welding wire (A6 TF)

1. Mount the wire drum according to the instructions on page 70.

2. Check that feed roller (1) and contact jaw or contact tip (3) are of the correctdimension for the selected wire size.

3. For A6 TF (Twin):

S Feed the wire through the wire guide (8).

4. When welding with fine wire:

S Feed the wire through the fine Wire feed unit (6).

Ensure that the straightener is correctly adjusted so that the wire emergesstraight out through the contact jaws or contact tip (3).

5. Pull the end of the wire through the straightener (2).

S For a wire diameter greater than 2 mm; straighten out 0.5 m of wire and feedit by hand down through the straightener.

6. Locate the end of the wire in the feed roller (1) groove.

7. Set the wire tension on the feed roller with the knob (4).

S Note! Do not tension more than is required to achieve an even feed.

8. Feed the wire forward 30 mm by pressing on the control boxA2--A6 Process Controller (PEH).

9. Direct the wire by adjusting the knob (5).

S Always use a guide tube (7) to ensure even feed of fine wire (1.6 -- 2.5 mm).

4.3 Changing the feed roller (A6 TF)

Single wire

S Release the knobs (3) and (4).

S Release the hand wheel (2).

S Change the feed roller (1).They are marked with their respective wire sizes.

Twin wire (Twin--arc)

S Change the feed roller (1) with twin grooves in the same way as for single wire.

S NOTE! The pressure roller (5) must also be changed. A special curved pressureroller for twin wire replaces the standard pressure roller for single wire.

S Assemble the pressure roller with special stub shaft(order no. 0146 253 001).

Flux--cored wire for knurled rollers (Accessories)

S Change the feed roller (1) and pressure roller (5) as a pair for the wire size to beused.

NOTE! A special stub shaft is required for the pressure roller(order no. 0212 901 101).

S Tighten the pressure screw (4) with moderate pressure to ensure that theflux--cored wire does not deform.

4.4 Contact equipment for Submerged arc welding

4.4.1 For single wire 3,0 -- 6,0 mm

Use automatic welding machine A6 TF (UP) wherethe following are included:

S Wire feed unit (1),

S Connector D35 (2)

S Contact jaw (3)

Ensure that good contact is achieved between thecontact jaws and the wire.

4.4.2 For twin wires 2 x 2,0 -- 3,0 mm (D35)

Use automatic welding machine A6 TF (UP, Twin)where the following are included:

S Wire feed unit (1),

S Connector Twin D35 (2)

S Contact jaw (3)

Ensure that good contact is achieved between thecontact jaws and the wire.

4.5 Refilling with flux powder (Submerged arc welding)

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 must be dry. Where possibleavoid using agglomerating flux powder outdoors andin damp environments.

4. Position the flux tube so that it does not becomekinked.

5. Adjust the height of the flux nozzle above the weld sothat the correct amount of flux is delivered.

Flux coverage should be sufficient so that penetrationof the arc does not occur.

4.6 Conversion of A6 TF (Submerged--arc) to MIG/MAG weldingAssemble in accordance with the instructions accompanying the conversion kit.

4.7 Conversion of A6 TF (submerged--arc welding) to Twin--arcAssemble in accordance with the instructions accompanying the conversion kit.

5 MAINTENANCE

5.1 General

Note:All warranty undertakings given by the supplier cease to apply if the customerattempts to rectify any faults on the machine during the warranty period.

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

For the maintenance of the A2--A6 Process Controller (PEH), see the instructionmanual 0443 745 xxx.

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 notworn or damaged.

S Check the brake hub braking torque. It should not be so low, that the wire reelcontinues to rotate when wire feed is stopped and it should not be so great thatthe feed rollers slip. As a guide, the braking torque for a 30 kg wire reel shouldbe 1,5 Nm.To adjust the braking torque see on page 70.

5.3 Periodic

S Inspect the electrode feed unit’s electrode control, drive rollers and contact tip.

S Replace worn or damaged components.

S Inspect the slides, lubricate them if they are binding.

S Lubricate the chain.

S Tensioning the chain between the trolley’s front and back axles.

S Dismantle the trolley wheels and blanks. Remove the Y flange bearing bolts.

S Tension the chain by moving the trolley’s rear axle parallel in relation to thefront axle.

S Reassemble in the reverse order.

S Tensioning the chain from the trolley’s front axle to the drive motor andgearbox.

S Tension the chain by moving the drive motor and gearbox.
