Troubleshooting
possible solution
1. test for good contacts; correct the wiring.
2. ensure circuit size is suitable for this machine;
replace weak breaker.
3. ensure main on/oFF switch is turned ON; replace
switch.
4. Check for broken wires or disconnected/corroded
connections, and repair/replace as necessary.
5. replace weld button.
1. remove debris, oily substances, or flash from weld
clamps and blade.
2. use the blade shear to cut blades; grind ends
together (see Note on top of Page 8).
3. Make sure blade ends are evenly butted against each
other before securing with clamp levers (Page 8).
4. set clamp pressure correctly according to tables on
Page 9.
1. Make sure blade ends are evenly butted against
each other in clamps; use the correct clamp pressure
(Page 8).
2. use the blade shear to cut blades; grind ends
together (see Note on top of Page 8).
1. Correctly perform the annealing procedure on
Page 11.
2. only grind flash even with blade body.
3. Make sure clamps and blade ends are clean of
debris, oily substances, and flash.
4. use light passes with the grinding wheel.
