EWM M3.7X-O Operating Instructions Manual page 61

Example for the operating point in correction operation:
The wire f eed speed in a program (1 to 15) is set to 10.0 m/min. This corresponds to a welding voltage
(U) of , for example, 21.9 V. When the key switch is now turned to position
out with these values in this program.
If the welder is also to carry out wire and voltage correction in program mode, correction operation must
be switched on and limit values for wire and voltage must be specified.
Setting the correction limit for wire = 20 %.
Setting the correction limit for voltage = 1.9 V.
The wire f eed speed can now be corrected by 20% (8.0 to 12.0 m/min) and the welding voltage by +/ - 1.9
V (3.8 V).
In the example, the wire f eed speed is set to 11.0 m/min. This corresponds to a welding voltage of 22 V.
Now the welding voltage can be corrected by 1.9 V (20.1 V and 23.9 V).
When the key switch is turned to position , the values for voltage and wire feed speed correction
are reset.
Setting the correction range:
• Activate the special parameter "Correction operation" (P7=1) and save > see 5.9.1 chapter.
• Key switch to position .
• Set the correction range as follows:
• If the user is inactive for about 5 seconds, the pre-set values will be applied and the display switches
back to the program display.
• Turn the key switch back to position
