- TIG/TIG Pulse/MMA mode :
Push button to choose a welding mode
- Control buttons:
rotary control to adjust the values of the parameters chosen keys.
- 2T/4T button:
“2T” n is short welding, pressing button will power up when released, stop
power supply. The first is the power button is pressed “4T” was and will remain so until the
next time you press the button.
- Base rate:
this button controls the volume of stream valleys.
- Given current :
controls the pulse peak current of
- Ramp-up time:
after the start of welding , the current should rise to a gradual current , this
feature controls the current rise time . If foot pedal is used, this button is “ 0” , adjustable
by turning counterclockwise .
- Deceleration time :
After completion of welding , the current should be reduced gradually
halt , this function controls the power loss time . If foot pedal is used, this button is “ 0” ,
adjustable by turning counterclockwise .
- Starting current:
after the start of welding , the current should rise to a gradual welding cur
-
rent, this function is governed by the initial value of the current.
- Ramp- current:
After completion of welding , the current should decrease to a stop gradu
-
ally , this function controls the final value of the current.
- Gas after-flow time:
workpiece oxidize due to heat and must be cooled by gas welding
completion of approx. To 10s, this button controls the after-flow time.
- Gas pre -flow time :
To ensure the efficiency of the gas flow in welding time must begin
before the power surge, this switch controls the time between gas and electric start.
- Pulse frequency :
the function sets the pulse frequency ( 0.5 to 300 Hz )
- Pulse duty:
duration of the pulse cycle regulates this function . This means that the peak
power of the pulse phase for longer or shorter cycle than the base current phase. The two
sections can not be achieved the best results melt of equal length , adjusting the rate.

Operation Steps of DC TIG Welding
- Connect the welding machine to the input power supply and power the welding machine
on. In such case, power on the machine and let it have a self-check; and the screen will
display: Full display->HYL->Model such as 200-> Enter the previous welding status.
- Press the TIG/MMA function selector switch, then the DC TIG indicator will be on and the
welding machine will change into the DC TIG status.
- Press the parameter setup selector key to set welding parameters such as pre-blow time,
arc striking current, rise time, given current, fall time, arc stopping current, afterblow time,
etc; with the regulation knob (2), you may respectively adjust the above parameters.
- Press the 2T/4T selector key to choose 2T or 4T.
- After regulating the welding current, save such welding parameter as unit n; for the next
use, you may directly call the parameters in the storage unit n.
- Please note the rated welding current and duty cycle; DO NOT use the welding machine
under overload.
·After the welding is over, turn off the power switch and then disconnect the input power.
