b) Welding Output

Welding process Symbol e.g.:

Manual metal arc welding with covered electrodes

Tungsten inert-gas welding

Metal inert and active gas welding including the use of flux cored wire

Selfshielded flux cored arc welding

Submerged arc welding

Symbol for plasma cutting

Symbol for plasma gouging

Symbol for welding power sources which are suitable for supplying power to welding operations carried out in an environment with increased hazard of electric shock (if applicable).

Welding current symbol e.g.:

Direct current

Alternating current, and additionally the rated frequency in hertz e.g.: ~50 Hz

U0... V Rated no-load voltage

a)Arithmetic mean value in case of direct current

b)RMS value in case of alternating current

c)Ur... V Reduced rated no-load voltage in case of a voltage reducing device

d)Us... V Switched rated no-load voltage in case of an a.c. to d.c. switching device

Box 10

... A/... V to... A/... V Range of output, rated minimum and maximum welding current and their

 

corresponding conventional load voltage.

Box 11

X Duty cycle (duty factor) symbol.

Box 12

I2

Rated welding current symbol.

Box 13

U2

Conventional load voltage symbol.

Boxes

11a, 11b, 11c ...% Values of the duty cycle (duty factor).

 

12a, 12b, 12c ... A Values of the rated welding current.

 

13a, 13b, 13c ... V Values of the conventional load voltage.

These boxes form a table with corresponding values of the three settings:

a)... % duty cycle (duty factor) at the rated maximum welding current;

b)60 % duty cycle (duty factor); and

c)100 % duty cycle (duty factor) as far as relevant.
