- Switching off the MAX 503 and MAX 503 IP44 generator: turn the main switch to
position 0 (ref.16 page 51) .
- When the generator is switched on, all the warnings will be displayed for about 2

1) The machine live led (ref.1 page 51-52) is lit.
2) The arc lit led (ref.2 page 51-52) is enabled.
3)
Regulating the welding current
Use the encoder
A
(ref.11 page 51-52) to regulate the welding current which will
be shown on the display (ref.4 page 51-52). The current may be regulated from 4
to 500A.
4) The Hot-Start function is already automatically regulated to have optimum
welding.
5)
Regulating the Arc-Force function
The function is accessed by turning the encoder for regulating the Arc-Force
(ref.10 page 51-52). The blinking letters A.F. appear on the display and then the
value which can be varied from 0 to 500% of the set welding current. 3 seconds
after the end of regulation the display again shows the set welding current.

) Displaying the welding voltage
During welding the display (ref.4 page 51-52) automatically shows the real
welding current: to display the welding voltage press the button
V
(ref.5 page 51-
52); the led (ref.6 page 51-52) blinks intermittently. To exclude the voltage display
press the button
V
(ref.5 page 51-52) .
