CAUTION: If the saw blade is rusty, the rust must be ground off before the blade is welded
.
WELDING
1.
Turn pressure knob to “0” position.
2. Butt blade ends together and locate joint in the center between the two
electrodes.
3. Set pressure knob to blade width. (Due to the different materials and thickness of
blade, please pay especial attention to the pressure adjustment. Thicker the
blade higher the pressure setting.)
4. Press and hold welder button.
Do not release until the blade joint is “red” hot.
The switch is automatic and will shut welder off after a preset time of 3 or 4
seconds and the blade returns to original color.
Note: The weld joint may throw
sparks during welding so wear safety glasses and proper apparel.
ANNEALING (Carbon Blades)
1. Turn pressure knob to “0” position.
2. Release blade and center the weld joint at the front of the electrodes. (At the wider part)
3.
Press and jog the annealing switch button until the weld is a “dull cherry” to “cherry red”
color. Allow the blades to cool slowly by decreasing the jogging frequency.
4. Perform the annealing operations 4 or 5 times, gradually reducing the heat each time.
5. Remove any welding dust or scale from the joint and anneal 2 or 3 more times,
successively at lower temperatures. (quicker series of press and release of annealing
button)
