1. Connect the work-holding pliers to the red output
socket.
2. Depress the purge switch for 3 or 4 seconds to rid the
system of air.
3. Reset the mode to "Arc".
4. Set the energy level to the desired value.
5. Prepare the wires to be welded and grip in the pliers,
leaving about 1mm or more protruding.
6. Position the wires 5 or 6mm in front of the carbon,
whilst steadying the hand.
7. Press the "weld" switch or foot switch and slowly
move the work towards the carbon until the arc is
struck.
8. Release the switch and remove the work for
examination.
Preparation of Wires for Arc welding
For small diameter wires, strip off about 12mm of
insulation and twist together. Then, with side cutters or
scissors cut the wire off square leaving sufficient
uninsulated material to give approximately 1mm
protruding when gripped in the welding pliers. Larger
diameter wires may be held side by side in the welding
pliers, but ensure that they are in firm contact with each
other and trimmed off square. This method will be found
useful for attaching solid leads to resistance thermometer
detectors. However, when attaching stranded leads, it
will be found more convenient to use the twisting method
and then to carefully untwist after welding.
