Figure 3-8 Operating mode selection zone
This zone contains display, parameters unit indicator,
warning indicator.
1.The window in the middle is a display to show all
parameters.
2.O.C on the left is over current protection indicator;
O.H is over heat protection indicator.
3.A、S、%、Hz on the right are parameters' unit of
current, time(second), duty cycle, HZ respectively.
For simple and efficient welding processing, this machine is equipped with 8 welding parameters storage channels
for DC TIG, Pulse TIG and DC MMA.
The so-called channel is operator's processing specification platform (it contains welding function, welding current,
operating mode and other parameters related with processing.) This machine is working in certain channel when it's
powered on and the channel it's located in is the previous working channel when the machine is turned off.
Check the channel number: press the channel key when machine is under standby and the display window

will show the current working channel. Eg. When the current working channel is #6, then the display will
show "CH-6".
Change the channel number: press the channel key when machine is under standby and the display window

will show the current working channel. Then adjust the rotary knob to change the working channel from 1`8.
Exit channel management: re-press the CH key to exit channel management.

Channel parameters invoking：press the channel key when machine is under standby and the display

window will show the current working channel. Then adjust the rotary knob to change the working channel
from 1`8. Re-press the CH key after selecting the according channel number and system will show all the
parameters under this channel for operator's usage.
Channel parameters' storage: after choosing the according channel number and invoking the needed

welding parameters, operator has to start welding processing to save the current parameters.
Remark：if there is no welding processing after operator's selection on channel number and welding parameters,
system will not save the current parameters; which means, if the machine is turned off then turned on, it will
automatically go back to the previous channel number and welding parameters.
