Arc Welding
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
un-insulated 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.
