3.9 Welding conditions of WB-M350/M400/M500
3-29
3.9.2 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
The WB-M350/500 has two modes: synergic adjustments and individual adjustments.
When it is used in the synergic adjustment, the optimum voltage for the current which has been
set is output automatically. The “arc length tun.” is an adjustment value for increasing or reducing
the voltage which is output automatically. 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.
Concerning the arc characteristic
The arc characteristic is the value that enables to set hard/soft of the arc. Intensive and hard arcs
are generated by increasing this value to the (–) side, while extensive and soft arcs to the (+) side.
When crater treatment is not performed
When crater treatment is not going to be performed, set the crater time to “0.” However, in this
case, set the same conditions as for regular welding as the crater current or wire feed speed
setting value. Unless the same conditions are set, the appropriate burnback voltage level may not
be displayed properly at the teaching stage.
IMPORTANT
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.
