• Fast pulse
Pulse frequency in the range of 250 Hz to 5 Hz.
• Normal pulse
Pulse frequency in the range of 25 Hz to 0.5 Hz.
• Normal welding
Normal TIG welding without pulsation.
Rotary switch I1 determines the ignition behaviour for electrode and
TIG welding. It can be set as a percentage of the possible welding
current of the power supply.
Sets the current I2 pulse time.
Sets the welding current. The welding current can be set during
no-load operation and is shown in the 7 segment display.
LED illuminates, when the welding current I2 is active. During pulsed
operation: Toggles between the displays I2 and I4 with fixed pulse
frequency.
Sets the pulse time of the current I4.
Sets the final current I3.
Select a value so that no craters are caused.
