GYS TIG 220 DC Manual De Instrucciones página 21

Example :
The I welding current is set to a 100A and % (I_cold) = 50%, thus a Cold current of = 50% x 100A = 50A. F(Hz) is set to 10Hz, the signal period
will be 1/10Hz = 100ms.
Every 100ms, a 100A pulse then a 50A pulse will succeeed each other.
The choice of frequency
- If welding with TIG electrodes, then F(Hz) synchronised to the gesture,
- If thin plate without TIG electrodes (< 8/10 mm), F(Hz) >> 10Hz
- If special metal requiring a welding pool sweep for degasing, then F(Hz) >> 100Hz

T1 - The main button is pressed, the welding cycle starts (PreGas,
I_Start, UpSlope and welding).
T2 - The main button is released, the welding cycle is stopped (DownS-
lope, I_Stop, PostGas).
For the double button torch and in 2T mode only, the secondary but-
ton works like the main button.
