from the Mains Supply Voltage before disassembling.
Welding equipment should be regularly checked by a qualified electrical tradesperson to ensure that:
•
The main earth wire of the electrical installation is intact.
•
Power point for the Welding Power Source is effectively earthed and of adequate current rating.
•
Plugs are correctly wired.
•
Flexible cord is of the 3-core tough rubber or plastic sheathed type of adequate rating, correctly
connected and in good condition.
•
Welding terminals are shrouded to prevent inadvertent contact or short circuit.
•
The frame of the Welding Power Source is effectively earthed.
•
Welding leads and electrode holder are in good condition.
•
The Welding Power Source is clean internally, especially from metal filing, slag, and loose
material. If any parts are damaged for any reason, replacement is recommended.
