18. Squeeze (and hold) the Trigger Switch (13E) of the Welding Torch (15E) and stroke
the area to be welded with the Welding Wire to ignite the arc.
A. Never tap the Welding Wire into the welding surface to ignite the arc. This will
cause the Welding Wire to stick to the workpiece.
B. For a narrow weld, you can usually draw the Welding Wire in a steady straight
line. This is called a “stringer bead”.
C. For a wider weld, draw the Welding Wire back and forth across the joint in a
curve. This is called a “weave bead”.
19. NOTE: If too much current is drawn from the Welder, the internal Thermal Overload
Protector will activate. The Overload Indicator Light (7D) will illuminate and the
Welder will automatically turn off. If this happens, turn the Power Switch (4D) to its
“OFF” position and wait 3 to 5 minutes for the unit to cool down. (See Figure P.)
20. After a few seconds, stop. Switch off the Welder, and check your progress. Compare
your weld’s appearance with the diagrams and descriptions shown in the
“Weld
Diagnosis” section beginning on page 23. After making any necessary adjustments,
continue the weld while carefully following the DUTY CYCLE guidelines.
(See Figure N.)
VOLT-AMPERE CURVES
Volt-Ampere Curves show minimum and maximum voltage and amperage output
capabilities of the Welder. Curves of other settings fall between the curves shown. (See
Figure O.)
