DCEN: Connect the electrode holder
to “
－
” output terminal, and the work clamp to “
＋
” output terminal.
4.3 Operation
Main switch (3):
Switch
the power switch on the back panel to “ON”, the machine is started with the power LED
on and the fan working.
/
switch (4):
Toggle between TIG and MMA.
◆
TIG operation
1) Switch the
/
switch to “
”.
2) Open the gas valve of the cylinder, and adjust the gas regulator to the desired value.
3) Switch
the power switch on the back panel to “ON”, the machine is started with the power LED on and the fan
working. Press the torch trigger, the solenoid valve works and there is gas output.
4) Adjust the welding current according to the thickness of the workpiece.
5) Keep the torch 2~4mm away from the workpiece, and then press the torch trigger. After arc is ignited, the HF
discharge rustling disappears, and welding can be carried out.
◆
MMA operation
1) Switch the
/
switch to “
”.
2) Adjust the welding current according to the thickness of workpiece.
Welding current knob (5):
to adjust the output current.
Overheating LED (6):
to indicate overheating. Overheating LED on indicates that the temperature inside the
machine is too high and the machine is under overheating protection status.
Digital meter (7):
to display the welding current value. (Applicable to TIG300S/TIG250/TIG300/ only)
Pulse selecting switch (8):
Switch the
/
switch to “
”, and then set
. Note: “
” -- no pulse;
“
” -- medium frequency; “
” -- low frequency. (Applicable to TIG180P/200P only)
2T/4T switch
（

）
:
This function can be added upon customers’ request.
Select proper welding mode 2T or 4T. Note: 2T
– General pulsed TIG welding; 4T – Multifunctional welding.
The operation in 4T is as follows: Adjust the arc ignition current, upslope time, welding current, base current,
downslope time, crater current and post-flow time according to the welding application requirement. Keep the
torch 2~4mm away from the workpiece, and then press the torch trigger. After arc is ignited, release the torch
trigger, and current will slowly increase to the peak current value. Then, normal welding can be carried out.
