4 INSTALLATION

WARNING

This product is intended for industrial use. In a domestic environment this prod-

uct may cause radio interference. It is the users responsibility to take adequate

precautions.

LPG 50/80 is delivered with 3 m mains cable.

The power supply is connected to a wall socket with isolator and fuses (see techni-

cal data). Extension cables between the wall socket and the power supply should

consist of four insulated wires (3 phases and earth), dimensions (see technical data).

1. Compressed air connection 8. Hold function

(max 10 bar) 9. Current regulation

2. Air regulator and filter 10. Override connection

(set to 4,3 bar) 11. Pilot arc connection

3. Air hose 12. Air connection

4. Main power switch 13.Earth connection

5. Lamp white on/off 14.Safety cut--out

6. Lamp warning

7. Air test

COMPRESSED AIR

Always use clean and dry compressed air, do not connect the unit to outlets with mist

lubrication. The air pressure from the compressor or outlet is set to 5 bar and may

under no conditions exceed 10 bar which is the maximum working pressure for the

power supply’s air regulator.

bp02d12e

S Main po wer switch: IN the ON position the lamp shines white indicating that

the auxillary circuits and the cooling fan are in operation.

S Current regulation: Stepless from 10--50 A/10--80 A.

S Switch--air test: In the ON position the air pressure can be set (4,3 bar) be-

fore cutting. Let the air flow through for several minutes to ensure that any

condensation that may have gathered during a period of little or no flow is

blown clear. Check that the switch is in the OFF position before cutting

starts.

S Switch--hold function: In the ON position the operator can release the cut -

ting switch once the cutting arc has started. To stop cutting the operator must

press and release the cutting switch once more (4--stroke). In the OF F posi-

tion the operator must keep the cutting switch depressed during the whole

cutting operation and release it to stop cutting. (2--stroke).

S Lamp--warning: If the lamp lights only when you press the cutting switch,

one of the following faults has occurred.

-- Overheating, thermo guard activated (open).

-- Duty factor exceeded, 50A/40% (10 min) / 80A/60% (10 min).

-- Primary over current, faulty power supply.

-- Low pressure (flow), flow guard not activated, air not connected.

S The lamp lights as soon as the machine is switched on:

-- Over/under voltage on the m ains <360 eller >460 V.

5OPERATION

LPG 50/80 are portable plasma cutting equipment ready to use once connected to

power and air supply.

NB!

Position the power supply at least 3 m away from the cutting area. Sparks and

hot slag products can damage the power supply.

WARNING!

The plasma cutting equipment operates with high open circuit voltages. Only

use the original cutter torch PT27. Do not use the equipment for any other

purpose than plasma cutting.

WARNING!

Touchin g live parts o f the cutter can cause loss of life. Always tu rn the power

supply off before replacing nozzles, electrodes, protective cone etc.

5.1 Cutting with the PT27 torch

1. Hold the torch about 3 m m from the work piece at an angle of 15--30_ .Ifthecut-

ting support is used the recommended gap is 1.5 mm for materials under 6 mm

and 4.5 mm for materials over 6 mm.

2. Press in the cutting switch, this starts the air flow and the high frequency current.

3. Two seconds after the cutting switch is pressed the pilot arc is lit. Immediately

after this cutting starts automatically. (If the hold function is activated, 4--stroke,

the cutting switch can be r eleased once the cutting arc has started).

4. Once cutting has started the torch can be righted to vertical. If cutting without the

support a gap of 3 m m between the cutting nozzle and the work piece is recom-

mended.

5. At the end of the cut the cutting switch is released (pressed in and released if the

hold function, 4 stroke, is activated). The torch should be lifted slightly just before

the end of the cut to reduce the risk for twin arcs which can damage the cutting

nozzle. T his stops the high frequency current from restarting once the cutting arc

has stopped.

6. During the after flow period the cutting arc can be restarted by pressing the cut-

ting switch. The gas flow period of two seconds is automatically bypassed.

5.2 Hole cutting

1. When cutting holes the torch is angled which prevents molten material from

damaging the cutting nozzle and torch.

2. Once the arc cuts through the material the torch can be righted to vertical and

cutting can commence.

5.3 Common cutting problems

Listed below are the most common cutting problems and their causes. If the prob-

able cause of the problem is in the power supply and cannot be fixed using the man-

ual contact ESAB Sverige AB or your nearest authorised service workshop.

1. Insufficient cutting penetration

-- Cutting speed too high

-- Worn cutting nozzle

-- Wrong air pressure setting

2. Arc stops during cutting

-- Cutting speed too low

3. Slag accu mulation

(For certain materials and thickness it is impossible to achieve a completely

slag free cut.)

-- Cutting speed too high or too low

-- Wrong air pressure setting

-- Worn cutting nozzle or electr ode

4. Twin arc (cuttin g nozzle d amaged)

-- Air pressure too low

-- Worn cutting nozzle

-- Loose cutting nozzle

-- Large volume of cutting sparks

5. Unstable arc

-- Worn cutting nozzle or electr ode

6. Unstable cutting effect

-- Wrong cutting speed

-- Loose cable or hose connections

-- Worn cutting nozzle or electr ode

7. Cutting arc does not start

-- Loose cable connections

-- 4 7 --bp02d12e

8. Consumables wear too quickly

-- Wrong air pressure

-- Impurities in the compressed air
