3.12 Welding conditions of WB-W350/W400
3-49
*2: RS control can be used only when using a servo torch. For details, refer to Section 1.2.4 in
"Chapter 1 Introduction".
3.12.2 Points for setting the conditions
The points to be observed when setting the welding conditions are set forth below.
Concerning the welding current and wire feed speed
The welding current (or wire feed speed) which is input as a welding condition becomes the
average current (or average wire feed speed) during welding. The welding waveform control
parameter optimally suited for the welding current (or wire feed speed) which has been set is
calculated automatically on the basis of the welding current (or wire feed speed) which has
been input.
Concerning the arc length tuning
For instance, if a setting of +5 is used, the output voltage will be raised by about 0.5 V as a
theoretical value.
Concerning the input of the wire feed speed
The wire feed speeds which are actually valid as welding conditions differ according to the
welder and welding mode used. If the standard software has been installed in the welder, the
minimum speed is approximately 130 cm/min. and the maximum speed is approximately
1800 cm/min. as a general rule. However, depending on the welding mode, the maximum
and minimum wire feed speed may be more restricted than the ranges given
Concerning the setting range of the welding speed
Although any speed from 1 to 999 cm/min. can be set as the welding speed, the maximum
speed is actually 600 cm/min. or so. Since this is also the maximum operable speed and not
a speed which can be used for actual welding, it must be adjusted to ensure optimum
welding.
When
the crater time has been set at 0, the “Welding method” for the arc end condition
shall be set to the same one for the main welding.
Concerning the pulse conditions
To adjust the pulse conditions, proceed by changing “arc characteristic” and “pulse
frequency”, described in Table 3.12.1. And refer to “3.12.3 To adjust the pulse conditions”
