ELECTRICAL SAFETY
WARNING! It is the user's responsibility to check the following:
Check all electrical equipment and appliances to ensure that they are safe before using. Inspect power supply leads, plugs and all
9
electrical connections for wear and damage. Sealey recommend that an RCD (Residual Current Device) is used with all electrical
products.
Electrical safety information. It is important that the following information is read and understood:
Ensure that the insulation on all cables and on the appliance is safe before connecting it to the power supply.
9
Regularly inspect power supply cables and plugs for wear or damage and check all connections to ensure that they are secure.
9
Important: Ensure that the voltage rating on the appliance suits the pow er supply to be used and that the plug is fitted with the
correct fuse.
DO NOT pull or carry the appliance by the power cable.
8
DO NOT pull the plug from the socket by the cable.
8
DO NOT use worn or damaged cables, plugs or connectors. Ensure that any faulty item is repaired or is replaced immediately by a
8

1.1.1. Cable extension reels. When a cable extension reel is used it should be fully unwound before connection. A cable reel with an RCD
fitted is recommended since any product which is plugged into the cable reel will be protected. The section of the cable on the cable
reel is important and should be at least 1.5mm², but to be absolutely sure that the capacity of the cable is suitable for this product
and for others that may be used in the other output sockets, we recommend the use of 2.5mm² section cable.
WARNING! Be very cautious if using a generator to power the welder. The generator must be self-regulating and stable with regard
to voltage, wave form and frequency. The output must be greater than the power consumption of the welder. If any of these requirements
is not met the electronics within the welder may be affected.
NOTE: The use of an unregulated generator may be dangerous and will invalidate the warranty on the welder.
WARNING! The welder may produce voltage surges in the mains supply which can damage other sensitive equipment (e.g. computers).
To prevent this happening, it is recommended that the welder is connected to a power supply that does not feed any sensitive equipment.
IMPORTANT! If using welder to full capacity, we recommend a 16amp supply. We recommend you discuss the installation of a 16amp
industrial round pin plug and socket with your electrician.
