FUNCTIONS
TIG parameters selection zone
Press to circulate clockwise and select the required TIG parameter.
Please note: Ib, Hz and % is only available when TIG pulse (TIGP) welding mode is selected
Tspot is only available when in spot (•••) trigger mode is selected
Channel key
The TIG 300P is equipped with 8 welding parameters storage channels for DC TIG, Pulse TIG and
DC MMA.
When the TIG 300P is turned on, it will be working in a certain stored channel which will be the
channel previously used prior to being turned off.
To check the channel number, press the channel key while the machine is in standby mode and the
display window will show the current channel number, for example, when the current working channel is
number 6, then the digital display will show CH
- 6.
To change the channel number, simply press the channel key when machine is in standby mode and the
display window will show the current channel number, to change this use the rotary adjustment knob to
change the working channel number from CH
- 1 to CH - 8.
To exit channel management just press the CH key again.
Storing channel (weld) parameters is done by first choosing the required channel number you wish to
save too, then adjust the required user welding parameters, the operator then has to start the welding
process to automatically save the current welding parameters.
PLEASE NOTE:
If the operator does not strike an arc after making weld parameter adjustments on a selected channel
number, the system will not save the current parameters which means, if the machine is turned off then
turned back on, it will automatically revert back to the previous channel number and welding parameters.
To load stored channel parameters, press the channel key when the machine is under standby mode, the
digital display will show the current working channel. To access to required stores channel rotate the
control dial to change the channel numbers from CH
- 1 to CH - 8.
Re - press the CH key after selecting the required channel number and the system will now show all the
parameters under this channel for operator ’ s usage.
Tpre - Pre flow time Ib - Base current Hz - Pulse frequency
Is - Initial Current Tdown - Downslope time % - Pulse duty cycle
Tup - Upslope If - Final current Tspot - Spot welding time
Ip - Peak current Tpost - Post flow time
