Annex I Definitions applicable for the Annexes

The following definitions shall apply:

1. (1)

   ‘power source efficiency’ means the ratio, expressed in a percentage, of the output power at standardised welding conditions and standardised welding load voltages, to the highest power consumption of the power source;

2. (2)

   ‘idle state’ means the operating state in which the power is switched on and the welding circuit is not energised;

3. (3)

   ‘idle state power consumption’ means the power demand, in watts, in idle state;

4. (4)

   ‘power source’ means a device that utilises alternating current (AC) to either power one or more AC power outputs, or which converts AC to one or more DC power outputs, for the purpose of powering a welding equipment;

5. (5)

   ‘control panel’ means an overall operating interface, containing controls and indicators, between the user and the welding equipment;

6. (6)

   ‘equipment housing’ means a casing intended to protect the product from the environment, including ambient humidity and possible shock impacts;

7. (7)

   ‘battery’ means a device as defined in Article 3 of Directive 2006/66/EC of the European Parliament and of the Council^f1, in the sense also of ‘battery pack’ or ‘industrial battery or accumulator’ in the same Article;

8. (8)

   ‘welding torch’ means a device which delivers the welding current to the electrode, which may include transferring the current to a consumable electrode, where used, and which also delivers the shielding gas, where used, to the electric arc area;

9. (9)

   ‘gas supply hose’ means a supply hose specifically designed for supply of fuel gases (such as acetylene), compressed air and shielding gases used in welding, normally consisting of a tube and a protective cover, often specific to the gas type used, and sometimes to the operating conditions;

10. (10)

    ‘gas supply regulator’ means a device which reduces the higher pressure of the supplied compressed gases to the lower pressure that can be safely used in the welding equipment, often equipped with a metering valve or flowmeter to measure and/or control gas flow;

11. (11)

    ‘welding wire drive’ means a device, used to feed welding wire or filler material, that may be of the type of push, pull or a push-pull combination;

12. (12)

    ‘fan’ means a rotary bladed machine used to maintain a continuous flow of gas, typically air, passing through it and acts for instance as the internal cooling system for the power source;

13. (13)

    ‘electricity supply cable’ means an electric energy supply cable meeting the performance and safety requirements of internationally recognised welding cable standards;

14. (14)

    ‘professional repairer’ means an operator or undertaking which provides services of repair and professional maintenance for welding equipment;

15. (15)

    ‘spare part’ means a separate part that can replace a part with the same or similar function in a welding equipment.
