Due to the dangers of stray output currents damaging fixed wiring, the integrity of fixed wiring
supplying ESAB welding power sources should be inspected by a licensed electrical worker in
accordance with the requirements below.
Due to the dangers of stray output currents damaging fixed wiring, the integrity of fixed wiring
supplying ESAB welding power sources should be inspected by a licensed electrical worker in
accordance 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.
General
maintenance
checks
Welding equipment should be regularly checked by an accredited ESAB service provider to
ensure that:
1. Flexible cord is of the multi-core tough rubber or plastic sheathed type of adequate rating,
correctly 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.
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.
Repairs
If any parts are damaged for any reason, it is recommended that replacement be performed by an
accredited ESAB service provider.
Power
source
calibration Schedule
Output testing of all ESAB inverter power sources and applicable accessories shall be conducted
at regular intervals to ensure they fall within specified levels. Calibration intervals shall be as
outlined below -
1. For transportable equipment, at least once every 3 months; and
2. For fixed equipment, at least once every 12 months.
Calibration
requirements
Where applicable, the tests outlined in "Calibration parameters" section, shall be conducted by an
accredited ESAB service agent.
Table

Calibration
parameters
Testing requirements
Output current (A) to be checked to ensure it falls within applicable ESAB power source
specifications
Output voltage (V) to be checked to ensure it falls within applicable ESAB power source
specifications
Motor speed (RPM) of wire drive motors to be checked to ensure it falls within required ESAB
power source / wire feeder specifications
Accuracy of digital meters to be checked to ensure it falls within applicable ESAB power source
specifications
Periodic calibration of other parameters such as timing functions are not required unless a
specific fault has been identified.
