1. SAFETY INSTRUCTIONS
1.1. ELECTRICAL SAFETY
WARNING! Electrical installation of the inverter must only be carried out by a qualified electrician. Make sure that power supply
p
cable is correctly connected to earth. It is the user’s responsibility to read, understand and comply with the following:
p
You must check all electrical equipment and appliances before use, to ensure that they are safe. You must inspect power supply leads, plugs
and all electrical connections for wear and damage. You must ensure the risk of electric shock is minimised by the installation of appropriate
safety devices. An RCCB (Residual Current Circuit Breaker) should be incorporated in the main distribution board. We also recommend that an RCD
(Residual Current Device) is used with all electrical products. It is particularly important to use an RCD together with portable products that are
plugged into an electrical supply not protected by an RCCB. If in doubt consult a qualified electrician. You may obtain a Residual Current Device
by contacting your Sealey dealer. You must also read and understand the following instructions concerning electrical safety.
1.1.1. The Electricity At Work Act 1989 requires all portable electrical appliances, if used on business premises, to be tested by a qualified
electrician, using a Portable Appliance Tester (PAT), at least once a year.
1.1.2. The Health & Safety at Work Act 1974 makes owners of electrical appliances responsible for the safe condition of the appliance
and the safety of the appliance operator. If in any doubt about electrical safety,
contact a qualified electrician.
1.1.3. Ensure the insulation on all cables and the product itself is safe before connecting to
the power supply. See 2.1.1. & 2.1.2. above and use a Portable Appliance Tester (PAT).
1.1.4. Ensure that cables are always protected against short circuit and overload.
1.1.5. Regularly inspect power supply, leads, plugs and all electrical connections for wear
and damage, and power connections to ensure that none is loose.
1.1.6. Important: Ensure the voltage marked on the product is the same as the electrical
power supply to be used.
1.1.7. DO NOT pull or carry the appliance by the power supply or output cables.
1.1.8. DO NOT pull power plug from socket by the power cable.
1.1.9. DO NOT use this product with an extension cable.
1.1.10. DO NOT use worn or damage leads, plugs or connections. Immediately replace or have
repaired by a qualified electrician.
1.1.11. Supply: 230Vac 1ph protected by a 16 amp delayed fuse or equivalent breaker, or
110Vac 1ph protected by a 25 amp delayed fuse or equivalent breaker.
1.1.12. Fit a plug according to the following instructions (see diagram at right - 110V plug shown).
Ensure the unit is correctly earthed via a three-pin 110V 25A or 230V 32A plug
(not supplied) to suit supply (see 1.1.11.).
a) Connect the GREEN/YELLOW earth wire to the earth terminal
b) Connect the BROWN live wire to the live terminal ‘L’.
c) Connect the BLUE neutral wire to the neutral terminal, unmarked.
d) After wiring, check that there are no bare wires, that all wires have been correctly connected, that the cable outer insulation
extends past the cable restraint and that the restraint is tight.
WARNING! Reminder, the electrical installation of the inverter must only be carried out by a qualified electrician. Make sure
p
that power supply cable is correctly earthed.
p
WARNING! Be very cautious if using a generator to power the inverter. The generator must be self-regulating and stable with
p
regard to voltage, wave form and frequency. The output must be greater than the power consumption of the inverter. If any
p
of these requirements is not met the electronics within the inverter may be affected.
NOTE: The use of an unregulated generator may be dangerous and will invalidate the warranty on the inverter.
WARNING! The inverter may produce voltage surges in the mains supply which can damage other sensitive equipment
p
(e.g. computers). To prevent this happening, it is recommended that the inverter is connected to a power supply that does
p
not feed any sensitive equipment.
2.2. GENERAL SAFETY
DANGER! Direct contact with the inverter circuit or electrode is dangerous. You MUST unplug the inverter from the mains power supply
s
before connecting or disconnecting cables or performing maintenance or service.
s
3 Keep the inverter, cables, holder and clamps in good working order and condition and take immediate action to repair or replace damaged parts.
3 Use recommended parts and accessories only. Unapproved parts may be dangerous and will invalidate the warranty.
3 Only use the electrode holder provided with the system and ensure any replacement is of the same type.
3 Use the inverter in a suitable work area. Ensure that the area has adequate ventilation as welding fumes are harmful.
For enclosed areas we recommend the use of an air and smoke extraction system. If you are not able to provide adequate extraction
and/or ventilation, wear a respirator suitable for protection against toxic fumes, smoke and gases.
3 Ensure that there are no obstructions to the flow of clean, cool air and that there is no conductive dust, corrosive vapour or humidity which
could enter the unit and cause serious damage.
