Table 7-1: Minimum Insulation Resistance Requirements: Cigweld Inverter Power Sources
C. Earthing
The resistance shall not exceed 1Ω between any metal of a power source where such metal is required
to be earthed, and -
1. The earth terminal of a fixed power source; or
2. The earth terminal of the associated plug of a transportable power source
Note that due to the dangers of stray output currents damaging fixed wiring, the integrity of fixed wiring
supplying Cigweld welding power sources should be inspected by a licensed electrical worker in ac-
cordance with the requirements below:
1. For outlets/wiring and associated accessories supplying transportable equipment - at least once
every 3 months; and
2. For outlets/wiring and associated accessories supplying fixed equipment - at least once every 12
months.
D. General Maintenance Checks
Welding equipment should be regularly checked by an accredited Cigweld Service Provider to ensure
that:
1. Flexible cord is of the multi-core tough rubber or plastic sheathed type of adequate rating, cor-
rectly connected and in good condition.
2. Welding terminals are in suitable condition and are shrouded to prevent inadvertent contact or
short circuit.
3. The Welding System is clean internally, especially from metal filing, slag, and loose material.
E. Accessories
Accessory equipment, including output leads, electrode holders, torches, wire feeders and the like shall
be inspected at least monthly by a competent person to ensure that the equipment is in a safe and
serviceable condition. All unsafe accessories shall not be used.
F. Repairs
If any parts are damaged for any reason, it is recommended that replacement be performed by an ac-
credited Cigweld Service Provider.
