ELECTRICAL CONNECTIONS
CONNECTING TO MAINS
NOTE:
This welder is earthed and must only be connected to the mains
with an earth connection. Do not attempt to use it without an
earth connection.
• This welder is not supplied with a mains electrical plug because at
full capacity it will draw far too much power for a normal domestic
230V mains plug and socket. This welder must not be fitted with a
standard 13A UK plug.
• A high current 230V mains socket or terminal must be installed by a
qualified and accredited professional electrician. A 16A socket and
plug conforming to IEC 60309 is recommended.
• A non-socketed mains connection also requires welder connection
by a qualified and accredited professional electrician. However, a
socketed connection is safer and more strongly recommended so
the welder can be safely isolated when necessary. If directly wired
to the mains, a double pole, double throw isolator switch must be
fitted.
• The welder must be connected using a circuit protected by an RCD.
• Please refer to the Specification for details of the maximum current
required by this welder.
• If in any doubt, do not attempt to connect or use this welder until a
professional electrician has been consulted.
