Legend:
(1) Symbol for the mains connection (number of phases, type of voltage, frequency)
(2) Mains voltage (here: 230 V)
(3) Symbol for mains fuse protection + "Snail symbol" for "slow-blow" (here: 16 A slow)
(4) Power consumption (here: 30 A) at maximum welding amperage (110 A) for the welding process "Rod-electrode
(5) Mean power consumption (here: 16 A) over the entire 10-minute duty cycle, determined from
N.B.! The mean power consumption is the basis for determining what level of fuse protection should be used.
(6) Apparent power, computed as the product of mean power consumption 5 x mains voltage (2) (here: 16 A x 230
(7) CE labelling
(8) Protection class as defined in the Standard (here: IP 23 = suitable for use on worksites)

Standard characteristic for WIG welding
The section on "Data regarding power
(5) (6)
supply" provides information on the
required mains power connection and the
necessary mains fuse protection. Other
data given here relate to the power
consumption, the degree of protection and
(7)
the CE-labelling of the power source.
As mentioned in the section headed "Data
regarding power supply", the power
consumption (4) - Fig.6 - is established
when the maximum welding current is
applied, with reference to the
corresponding output voltage as per the

Standard characteristic.

The Standard characteristic represents a
standardised ratio of welding voltage to
welding amperage

Figure 7 shows the standard
characteristics for rod-electrode welding
Figure 8 shows the standard
characteristics for TIG welding
Because the welding voltage measured at
the maximum welding current reaches
various different values, as dictated by the
conditions prevailing at the arc, it would
not be possible to make any concrete
statement on the maximum power
consumption (4) - Fig.6 - without a defined
current/voltage ratio.
