WARNING
There are extremely dangerous voltage and power levels present inside this Inverter Power Source.
Do not attempt to open or repair unless you are an accredited CIGWELD Service Provider. Discon-
nect the Welding Power Source from the Mains Supply Voltage before disassembling.
Routine Inspection, Testing & Maintenance
The inspection and testing of the power source and associated accessories shall be carried out in accordance
with Section 5 of AS 1674.2 - 2007: Safety in Welding and Allied Processes-Part 2 Electrical. This includes an
insulation resistance test and an earthing test to ensure the integrity of the unit is compliant with Cigweld's
original specifications.
If equipment is to be used in a hazardous location or environments with a high risk of electrocution as outlined
in AS 1674.2 - 2007, then the above tests should be carried out prior to entering this location.
A. Testing Schedule
1. For transportable equipment, at least once every 3 months; and
2. For fixed equipment, at least once every 12 months.
The owners of the equipment shall keep a suitable record of the periodic tests and a system of tagging,
including the date of the most recent inspection.
A transportable power source is deemed to be any equipment that is not permanently connected and fixed
in the position in which it is operated.
B. Insulation Resistance
Minimum insulation resistance for in-service Cigweld Inverter Power Sources shall be measured at a voltage
of 500V between the parts referred to in Table 6-1below. Power sources that do not meet the insulation
resistance requirements set out below shall be withdrawn from service and not returned until repairs have
been performed such that the requirements outlined below are met.
