WARNING

ARC WELDING AND CUTTING CAN BE INJURIOUS TO YOURSELF AND OTHERS. TAKE PRECAU-

TIONS WHEN WELDING. ASK FOR YOUR EMPLOYER’S SAFETY PRACTICES WHICH SHOULD BE

BASED ON MANUFACTURERS’ HAZARD DATA.

ELECTRIC SHOCK -- Can kill

S Install and earth the welding 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 keep fumes and gases 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 ear defenders 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!

Welding power source complies with IEC 974--1

Power cable rating complies with Swedish regulations.

The sym bol indicates that the power source is designed for use in areas where
there is an increased electrical hazard.
The IP code indicates the enclosure class, i. e. the degree of protection against
penetration by solid objects or water.
Equipment marked IP 23 is designed for indoor and outdoor use.

INSTALLATION

1. Installation must be carried out by a qualified electrician.

2. Check that the power source is set up for the available mains voltage before
connecting it to the supply.

3. If the control voltage is switched between 42 V and 110 V make sure the r evers­ible sign shows the correct voltage.

4. See the technical data for recommended power cable and fuse ratings.

5. Connect the power cable to the power source in accordance with the relevant
electrical regulations and fit a suitable fuse to the junction box.

6. Make sure that the flow of cooling air through the power source is not obstructed.

OPERATION

1. Switch
switches power on or off. The white lamp (2)
lights up and the fan starts.

2. Signal lamp, white, 42--48 V

3. Potentiometer
for adjusting welding voltage. Can be con­trolled remotely using additional servo motor
(e.g. from automatic welding machine)

4. Voltmeter och ammeter optional accessories

5. Switch and 3 pin socket
for remote control unit or pulse unit

6. 8 pin socket
for external control 110/42 V AC (allows
switching from automatic welding machine,
for example)

7. 1 pin socket for meter lead

8. Socket, for connecting wire feed unit

9. Thermal cut--out (overload protection)
when the thermal cut--out trips the yellow
lamp on the front panel comes on. When the
power source has cooled down the thermal
cut--out is reset automatically.

MAINTENANCE

Blow the power source clean at least once a year using dry compressed air at
reduced pressure. If the power source is used in a dusty or dirty environment it
should be blown clean more often.

Spare parts are ordered through your nearest ESAB representative, see back cover.
When ordering spare parts, please state machine type and number as well as desig­nation and spare part number as shown in the spare parts list on page 65.
This will simplify dispatch and ensure you get the right part.
