OBTAINING NEW ANNEAL SETTINGS
1) Set ANNEAL TIME 1 for 0.1 seconds
2) Set ANNEAL TIME 2 for 900.0 seconds
3) Set both ANNEAL HEAT 1 & 2 for 200 – 250
4) Load a blade of the desired size and initiate an anneal cycle
5) Adjust ANNEAL HEAT 2 until the desired temperature is reached and holds steady
6) Set ANNEAL TIME 2 for the desired soak time (probably around 3 – 5 seconds)
7) Set ANNEAL TIME 1 for the desired ramp time (usually around 5 seconds)
8) Set ANNEAL HEAT 1 around 50-100 points higher than ANNEAL HEAT 2
9) Load a fresh blade and initiate another anneal cycle
10) If needed, adjust the settings accordingly and repeat from Step 9 until the desired ramp and soak effect is achieved
AUTOMATIC WELDING & ANNEALING PROCEDURE
1) Select AUTO mode.
2) Setup for welding and annealing the desired blade size.
(See “WELD SETUP” & “ANNEAL SETUP”)
3) Set the ANNEAL DELAY time.
Type the time for the duration of the auto anneal delay into the ANNEAL DELAY TIMER.
4) Calibrate the machine, if necessary.
a) The welder is out of calibration if the green light does not come on and a ½-second beep sounds at the weld start position.
b) With both clamps UP, press the ADVANCE BUTTON to re-calibrate.
5) Select the desired clamping mode.

7) Advance to the weld start position.
a) Both clamps must be UP.
b) Press the ADVANCE BUTTON until the green weld light comes on.
8) Load the blade.
a) With both clamps UP, insert the blade-ends into the jaws with the teeth facing the operator.
b) The blade should be against all four blade guides.
c) Butt the blade-ends together leaving about a 0.010” - 0.020” gap between them and center the blade joint between the jaws.
d) Clamp the blade-ends in place making sure they are not overlapping, and the blade is against all four guides.
9) Press the WELD BUTTON to start the automatic weld cycle.
a) Both clamps must be DOWN.
10) Unclamp and remove the blade when the cycle is finished.
a) Automatic cycle is finished when both clamps release and the machine moves back to the weld start position after annealing.
