8 WORKING WITH MULTIPLE OPERATORS
It may occur that multiple operators need to use the machine with different settings; this is why the USER function
was introduced.
This function allows you to save and call up customized values, always recording the last value set for each program
and for each operator level.
The LEd B lights if the machine is being used by an operator. Briefly pressing the key A causes the display R to show
the letter L followed by a number, which is the one selected by the user. Press it briefly again to confirm the operator
and re-enable use of the power source.
How operator recognition works.
Briefly pressing ("brief" means less than 0.7 sec ) the button A (usER) causes the display R t show the abbreviation
L1 (level 1), and LEd B is off; pressing the s key activates level 2 and activates the function. The LEd B lights and the
display R shows the abbreviation L2. Pressing the key A confirms the level shown on the display and enables power
source operation.
The operator may activate, select, and adjust the desired functions. The settings are saved in the various operating
modes whenever the function changes, or 5 seconds after the last adjustment.
Let us imagine that operator 1 has stopped using the machine, and a second operator wishes to set up his
or her work.
The LEd B lights to signal to the second operator that the machine is already being used by a colleague; s/he then
presses the key A. display R shows the abbreviation "L2" (abbreviation of the operator who is using the machine).
s/he selects level "L3" and confirms it by pressing the key A. At this point the machine suggests the settings,
corresponding to the various functions set in "L3"; at this point the new user may set his or her adjustments without
changing the settings already saved by "L2."
To exit from operator recognition simply select level L1. The LEd B shuts off. Then briefly press the button A to confirm
exiting the function.
The button on the back of the gun allows the operator to select the machine functions without moving from the
working position.
9 MAINTENANCE
keep all instructions and figures on the welding machine clear and legible. The mains cable and welding cables must
be insulated and in perfect condition; be careful at the flex points: near the connector terminals, earth clamps and gun
input. All maintenance operations must be carried out by qualified personnel.
Before removing the panels, make sure that the machine plug is disconnected from the power supply panel.
The electrodes in use must be frequently cleaned of ferrous waste.
Periodically remove oil and grease not using sprayed water nor solvents on the painted parts.
