Safety precautions must meet the requirements that apply to this type of equipment. The following recommendations should be ob served in addition to the standard regulations that apply to the workplace.

All work must be carried out by trained personnel well-acquainted with the operation of the equip ment. Incorrect operation of the equipment may lead to hazardous situations which can result in in jury to the operator and damage to the equipment.

1. Anyone who uses the equipment must be familiar with:

S its operation S location of emergency stops S its function S relevant safety precautions S welding and cutting

2. The operator must ensure that: S no unauthorised person is stationed within the working area of the equipment when it is

started up.

S no-one is unprotected when the arc is struck

3. The workplace must:

S be suitable for the purpose S be free from drafts

4. Personal safety equipment S Always wear recommended personal safety equipment, such as safety glasses, flame-proof

clothing, safety gloves.

S Do not wear loose-fitting items, such as scarves, bracelets, rings, etc., which could become

trapped or cause burns.

5. General precautions

S Make sure the return cable is connected securely. S Work on high voltage equipment may only be carried out by a qualified electrician. S Appropriate fire extinquishing equipment must be clearly marked and close at hand. S Lubrication and maintenance must not be carried out on the equipment during operation.

WARNING

Arc welding and cutting can be injurious to yourself and others. Take precausions when welding and cutting. Ask for your employer's safety practices which should be based on manufacturers' hazard data.

ELECTRIC SHOCK - Can kill

S Install and earth the unit in accordance with applicable standards. S Do not touch live electrical parts or electrodes with bare skin, wet gloves or wet clothing. S Insulate yourself from earth and the workpiece. S Ensure your working stance is safe.

FUMES AND GASES - Can be dangerous to health

S Keep your head out of the fumes. S Use ventilation, extraction at the arc, or both, to take fumes and gases away from your breathing zone

and the general area.

ARC RAYS - Can injure eyes and burn skin.

S Protect your eyes and body. Use the correct welding screen and filter lens and wear protective

clothing.

S Protect bystanders with suitable screens or curtains.

FIRE HAZARD

S Sparks (spatter) can cause fire. Make sure therefore that there are no inflammable materials nearby.

NOISE - Excessive noise can damage hearing

S Protect your ears. Use earmuffs or other hearing protection. S Warn bystanders of the risk.

MALFUNCTION - Call for expert assistance in the event of malfunction.

Read and understand the instruction manual before installing or operating.

PROTECT YOURSELF AND OTHERS!

2 INTRODUCTION

The A21 PRD 100 pipe welding tool is designed for TIG welding of pipes in combina tion with the LTP 450 welding power source.

During pipe welding the tool runs along a toothed track, which is held in place by spring-loaded studs. There is a separate toothed track for each size of pipe. For flat work pieces there is a toothed track which is held in place by suction cups.

The A21 PRD 100 is attached to the track by a quick locking system which, when locked in place, grips the tool against the track to ensure that it is free from play and to prevent the tool from being dislodged accidentally.

5.1 Securing the welding tool for welding

S Attach the PRD 100 to the track using the locking mechanism.

S Adjust the angle between the two halves of the A21 PRD by means of screw (1),

so that one support wheel can be raised 1-2 mm above the track.

S Clamp the PRD 100 to the track by setting all locking screws to the ”closed”

position.

5.2 Narrow gap welding

Before narrow gap TIG welding with the PRD tool the electrode holder must be re placed and a wire straightener must be fitted to the wire feed unit, since the wire must be straight to ensure a stable stickout.

S Screw the wire straightener 0441 355 directly onto the wire feed unit.

There are three versions of wire straightener:

S Wire straightener 0441 355 880 for 1,2 mm

S Wire straightener 0441 355 881 for 1,0 mm

S Wire straightener 0441 355 882 for 0,8 mm

S Adjusting the wire straightener.

Turn the wire straightener in the desired direction on its threaded mount.

S Use 3.2 mm tungsten electrode for narrow gap welding.

S Replace electrode holder 0444 030 880 with:

S Electrode holder for narrow gap welding, order no. 0441 623 880 for plate

thicknesses up to 50 mm.

S Electrode holder for narrow gap welding, order no. 0441 623 881 for plate

thicknesses up to 80 mm.

dsb2d1ea

GB

S When welding plate thicker than 50 mm:

S Fit the gas shroud for 80 mm and weld until about 40 mm remains.

S Fit the accompanying gas shroud for 50 mm and complete the weld.

5.3 Welding start

S Recall the welding program to be used to the working

area (see programmering manual).

S Press the start button (A) on the control unit.

6 MAINTENANCE

CAUTION

All guarantee undertakings from the supplier cease to apply if the customer attempts any work to rectify any faults in the product during the guarantee period.

6.1 Once a day

S Check all cables and hoses for damage.

S Clean the pipe welding tool.

S Place a drop of oil in lubrication hole (2) on the wire feed unit.
