Pulse Welding; Automated Pulses - EWM T 4.00 - AC/DC Comfort 2.0 Operating Instruction

4.1.10 Pulse welding

The following pulse types can be selected:
•
Automated pulsing (TIG DC)
•
Thermal pulsing (TIG AC or TIG DC)
•
Average value pulsing (TIG AC or TIG DC)
•
Metallurgical pulsing (TIG DC)
•
AC special (TIG AC)

4.1.10.1 Automated pulses

The automated pulses are used with tacking and spot welding of workpieces in particular.
An oscillation in the molten pool is produced by the current-dependent pulse frequency and balance,
which positively influences the ability to bridge the air gap. The pulse parameters required are
automatically specified by the machine control.
