Welding processes
2. Welding processes
2.1 Definition arc length
Press the right rotary knob to switch between arc length and dynamics.
When the arc length is active, the "Dyn." LED is off. Turn the right rotary
knob to influence the length of the arc:
- 0 - The welding current is exactly on the characteristic curve.
- The wire speed is reduced, the arc becomes longer.
+ The wire speed is increased, the arc becomes shorter.
2.2 Definition Dynamics
Press the right rotary knob to switch between arc length and dynamics.
When dynamics is active, the "Dyn." LED lights. Turn the right rotary knob
to influence the shape of the arc:
- 0 - The welding current is exactly on the characteristic curve.
- The arc becomes softer and wider.
+ The arc becomes concentrated and smaller.
During the normal MAG process the shape of the arc is influenced in the
dynamic range. In the Rapid Weld process, the penetration shape and
depth can be influenced with the dynamic setting.
2.3 Hold value display
The Hold value display shows the averaged values for the last weld for
10 seconds. To activate the Hold value display, keep the Hold button pressed
until the display changes.
After the welding process, the Hold display will automatically be displayed
for 5 seconds. This function can be deactivated in the configuration menu
under "General".
2.4 TIG welding
This process is provided with a Lift Start ignition.
• Use the left rotary knob to select the welding current.
The displays for wire diameter and shielding gas are hidden.
