Welding parameters

The Welding parameters view includes a start and stop curve for visualizing and adjusting the most essential parameters for a weld. The bottom section of the view lists the available adjustments for the selected welding process. The welding process selection is based on the active memory channel and its settings.

Many of the welding parameters are welding process specific and are visible and available for adjustment accordingly.

Adjusting welding parameters

1. Select a welding parameter for adjustment.

>>  You can navigate in the parameter list also by selecting a phase in the start and stop curve.

2. Adjust the welding parameter value.

>>  Depending on the parameter to be adjusted, refer also to the Welding parameter tables below for more details.

3. Confirm the new value / selection and close the adjustment view by selecting 'OK'.

Welding parameters and feature descriptions

ClosedManual MIG welding parameters

The parameters listed here are available for adjustment with the manual MIG process.

Parameter Parameter value Description
Process Manual MIG, 1-MIG, Pulse, DPulse, WiseRoot+, WiseThin+, MAX Cool, MAX Speed, MAX Position This MIG welding process selection depends on the active welding program. For more information on the additional processes, refer to Additional guidance to functions and features.
Pre gas 0.0 ... 9.9 s, Auto, step 0.1
0.0 = OFF
Default = Auto
Welding function that starts the shielding gas flow before the arc ignites. This ensures that the metal does not come into contact with air at the start of the weld. Time value is preset by the user. Used for all metals, but especially for stainless steel, aluminum and titanium.
Creep start 10 ... 100 %, Auto, step 1
Default = Auto
The Creep start function defines the wire feed speed before the welding arc ignites, that is, before the filler wire comes in contact with the workpiece. When the arc ignites, the wire feed speed is automatically switched to the normal user-set speed. The Creep start function is always on.
Touch Sense Ignition Auto/OFF/ON
Default = Auto
Touch Sense Ignition delivers minimum spatter and stabilizes the arc immediately after ignition.
Wire feed speed 0.5 ... 25 m/min, step 0.05 or 0.1
Default = 5.00 m/min

Wire feed speed adjustment. When the wire feed speed is less than 5 m/min, the adjustment step is 0.05 and when the wire feed speed is 5 m/min or more, the adjustment step is 0.1.
Wire feed speed limit min Min/Max = 0.5 ... 25 m/min, step 0.1
Default = 0.5 m/min
Minimum and maximum limits for the wire feed speed adjustment.
Wire feed speed limit max Min/Max = 0.5 ... 25 m/min, step 0.1
Default = 25 m/min
Voltage 400 A: 8 ... 45 V
500 A: 8 ... 50 V
Step 0.1 V
Welding voltage adjustment and the minimum and maximum limits for the welding voltage adjustment.
Dynamics -10.0 ... +10.0, step 0.2
Default = 0
Controls the short circuit behavior of the arc. The lower the value the softer the arc, the higher the value the rougher the arc.
Robot travel speed 20...2000 mm/min, step 1 /
Controlled by robot
Default = Controlled by robot
The user can set the travel speed in a memory channel to be transmitted to the robot. However, note that:
- The robot must have a function that enables the use of the value transmitted from the memory channel.
- The travel speed can still be set directly in the robot program, in which case the value of the robot program overrides the value transmitted from the memory channel.
Crater fill ON/OFF When welding with high power, a crater is usually formed at the end of the weld. The Crater fill function decreases the welding power / wire feed speed at the end of the welding job so that the crater can be filled using a lower power level. With MIG process, crater fill time, wire feed speed and voltage are preset by the user.
When the wire feed speed is less than 5 m/min, the adjustment step is 0.05 and when the wire feed speed is 5 m/min or more, the adjustment step is 0.1.
For 1-MIG process, refer to the 1-MIG parameter table.
- Crater fill time 0.0 ... 10.0 s, Auto, step 0.1
Default = 1.0 s
- Crater fill wire feed speed 0.5 ... 25.0 m/min, Auto, step 0.05 or 0.1
Default = 5 m/min
- Crater fill voltage 400 A: 8 ... 45 V, Auto
500 A: 8 ... 50 V, Auto
Step 0.1 V
Default = 18V
Post current -30 ... +30 Post current setting affects the wire length at the weld end, for example to prevent the wire from stopping too close to the weld pool. This also enables the optimum wire length for the start of the next weld.
Wire feed end step (WF end step) OFF/ON
Default = OFF
Wire feed end step feature prevents the filler wire from sticking to the contact tip when the welding ends.
Post gas 0.0 ... 9.9 s, Auto, step 0.1
0.0 = OFF
Default = Auto
Welding function that continues the shielding gas flow after the arc has extinguished. This ensures that the hot weld does not come into contact with air after the arc is extinguished, protecting the weld and also the electrode. Used for all metals. Especially stainless steel and titanium require longer post gas times.

Default = 50
- Upslope time 0.1 ... 5 s, Auto, step 0.1
