Safety Notes

Thank you for choosing the Fine Wire Welder. This welder is designed
for producing commercial grade thermocouple hot junction. It’s easy
to use and operate. But it is still very important to read the instructions
carefully prior using the welder.

• Always wear protective safety glasses during welding. Do not view
the weld discharge with the naked eye.

• Do not touch directly welding electrode during welding operation.

• Follow the instruction carefully and use the correct power supply.

NOTE

Always wear protective eyewear during welding!

Always Wear

Eye Protection

Set Up Your Welder

• The welder should be placed on a stable and at working bench for
operation.

• Connect the welder to the power supply with the power cable.

• If using the argon mode, connect the argon hose securely to the argon

inlet at the rear of the welder.

• Adjust argon ow to 6 litres per minute. And check to make sure there is
no leakage.

• Switch on the power button.

• Now the welder is ready to use.

Adjust the power level according to the thermocouple wire diameter. As a reference, we suggest
the following:

•

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.

•

tip the wires to the Electrode for the welding arc struck.

•

•

NOTE

•

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.

Switch power o before you replace or adjust the Electrode!
