6.18 Wire creep start
Wire creep start is used to set the desired creep speed on the electrode motor upon start-up.
If, for example, 50 is set in the menu a creep speed of 50 cm/min is obtained.
Preset value ”AUTO” gives a creep speed calculated from the set values.
• Wire creep speed is set in the weld data setting menu under start data.
6.19 Start phases
When welding special wire or material, it may be necessary to create your own start
sequence. The start sequence can affect the appearance of the weld pool.
The following can be set for Start phase1
ON
• Time s
Time for welding in phase 1.
• Arc voltage %
In percent of set voltage
• Wire feed %
In percent of set wire feed
• Welding current %
In percent of set welding current
• Travel speed %
In percent of set travel speed
The following can be set for Start phase2
ON
• Time s
Time for welding in phase 2.
• Arc voltage %
In percent of set voltage
• Wire feed %
In percent of set wire feed
• Welding current %
In percent of set welding current
• Travel speed %
In percent of set travel speed
• Start phases are set in the weld data setting menu under start data.
6.20 Max Open Circuit Voltage (OCV)
ON means that OCV can be set.
OFF means that OCV is set to the set value for welding voltage.
• OCV is set in the weld data setting menu under start data.
6.21 Flux post-flow (SAW)
This controls the time during which flux flows after the arc is extinguished.
• Flux post-flow is set in the weld data setting menu under stop data.
6.22 Gas post-flow (GMAW)
This controls the time during which shielding gas flows after the arc is extinguished.
• Gas post-flow is set in the weld data setting menu under stop data.
6.23 Air post-flow (Gouging)
This controls the time during which air flows after the arc is extinguished.
• Air post-flow is set in the weld data setting menu under stop data.
