Adjust the power level according to the thermocouple wire diameter. As a reference, we suggest
the following:
Wire Diameter
20AWG (0.80mm)
28AWG (0.32mm)
30AWG (0.25mm)
36AWG (0.13mm)
40AWG (0.08mm)
Prepare the wires to the Appropriate length and ready for welding.
Grip in the pliers, leaving about 1mm or more protruding.
Adjust the approapriate power setting according to the wire diameter.
Keep steady and position in front of the Electrode.
If using the argon weld, connect the argon supply to the argon inlet at the back of the welder.
Use the argon switch turn the argon flow on and off.
ARGON ON keeps the argon flow on constantly.
LEVEL position switch off the argon flow.
PURGE is pressed to burst argon flow; release the switch to stop argon flow.
Wait for the READY led light turns green, hold the wires using the pliers and then touch the
tip the wires to the Electrode for the welding arc struck.
Check the wires welded correctly.
If using foot swtich to control the argon ow, connect the foot switch supplied. Press the foot
switch to enable argon ow. Release the foot switch to stop argon ow.
NOTE
Switch power o before you replace or adjust the Electrode!
Unscrew the black weld nozzle cap and put aside.
Reveals the electrode holder with the hexegonal socket.
Use the supplied hex key to loose the electrode holder.
Replace new electrode or adjust the electrode in position. Tilt the welder forward slightly where
necessary to pull out the electrode.
Tighten the electrode holder using the hex key.
Screw the welding nozzle cap in place securely.
If there is uneven working surface on the electrode, you may use sand paper or equivalent tools
to smooth the working surface of the electrode.
