2.4 PROTECTION DEVICES

2.4.1 Overheating and main supply anomalies protection
The power supply is protected by a device installed in such a way as to act in case of overheating and/or main supply
anomalies.
When this device intervenes, the unit stops supplying current but the cooling fan keeps working.
The turning off of the LED signals the resumed ability of the unit to be in operating conditions.

3.1 UNPACKING AND SETUP

Unpack the unit and carefully inspect it for shipping damages. Any claims for damages which may have occurred in transit must
be filed by the purchaser with the carrier and in order not to loose any right to file such a claim no clean receipt should be signed
but a mention should be made to reserve the right to file a claim for transit damages that can be discovered only after
unpacking.
All communications regarding this equipment must indicate the model and serial number located on the back of the power
supply.
After unpacking place the unit in a properly ventilated, possibly undusted area, making sure that the air flow near the cooling
slots in not obstructed.
WARNING: it is extremely important not to restrict the air flow around the unit since this may cause the unit to over heat and
could possibly damage internal parts. Keep at least 200 mm of unrestricted space on all sides of the unit.
Do not Place any filter device or cover over the air intake slots of the power supply as this will void the warranty.
NOTE: if the unit is carried over shoulder make sure that the air intake slots on the frame are not obstructed.

3.2 STARTUP PROCEDURE

This unit must be installed by skilled personnel. All connections must conform to the existing rules and in full compliance with
safety regulations (CENELEC HD 427).

3.3 GENERAL NOTES

Before using this power supply, carefully read the CENELEC standards HD 407 and HD 433, check insulation of cables,
electrode holder clamp, sockets and plugs and make sure that the length and section of welding cables are compatible with
current used:
Up to 5 mt. cable section 16 mm
From 5 mt. to 20 mt. cable section 25 mm
From 20 mt. to 30 mt. cable section 35 mm

4.1 DESCRIPTION OF CONTROL PANEL

On the front panel one finds:
1. Current adjustment knob
2. Electrode and earth clamp cable connectors
3. Welding current LED indicator (ok if on)
4. AC power input fault (voltage outside the + - 10% of 220 V range) or overheating condition LED indicator (OK if off).

4.2 COATED ELECTRODE WELDING

This power supply is suitable for welding with all types of electrodes. For the cellulose ones (AWS 6010), only specific power
supply can be used, see the technical tables.
Use electrode holder clamps in compliance with the safety standards and without projecting tightening screws.
Make sure that the main switch on the back is on 0 position or that main supply plug is not inserted in main outlet then connect
welding cables in accordance with polarity indications given by the electrode manufacturer.
The welding circuit should not be deliberately placed in direct or indirect contact with protection wire if not on piece to be welded.
If earthing is deliberately made on the work piece by means of protection wire, the connection must be as direct as possible,
with the wire having a section at least equal to the welding current return wire and connected to the piece being worked on, in
the same place as the return wire, using the return wire terminal or a second earth terminal closely.
All possible precautions must be taken in order to avoid stray currents.
