8. When everything is in place for welding, press the Power Switch to the On position.
Caution: Be careful not to touch anything else with the welding rod except the work-
piece.
9. Orient yourself on the area to be welded, then hold the Arc Shaded Face Shield over
your eyes. Then, strike the metal to begin welding.
Warning: Never look at the ignited arc without ANSI approved,
arc shaded, eye protection in a full face shield. Permanent
eye damage or blindness can occur. Skin burns can occur.
Never breath arc fumes.
Never tap the electrode wire into the welding surface to
ignite the arc. This damages its external coating on the
electrode which prevents oxygen in the air from coming
into contact with the molten metal, causing it to oxidize.
10. Once the arc is ignited, tilt the electrode wire forward at an
angle of about 35°. Refer to the illustration on the next
page.
11. When finished welding;
- slowly lift the Arc Welding Electrode Holder (53) from
the workpiece,
- press the Power Switch to the Off position,
- set the Arc Welding Electrode Holder (53) down on a nonflammable and
nonconductive surface,
- unplug the line cord plug from the outlet.
INSPECTION, MAINTENANCE, AND CLEANING
WARNING! Make sure the Power Switch of the welder is in its “OFF” position and
that the tool is unplugged from its electrical outlet before performing any inspection,
maintenance, or cleaning procedures.
1. Before each use, inspect the general condition of the welder. Check for loose screws,
misalignment or binding of the fan, cracked or broken parts, damaged electrical wiring,
and any other condition that may affect its safe operation. If abnormal noise or
vibration occurs, have the problem corrected before further use. Do not use damaged
equipment.
2. Periodically recheck all nuts, bolts, and screws for tightness.
3. Periodically blow the dust from the cooling vents with compressed air.
4. Verify that the cooling fan is operational before welding.
5. If an odd smell comes from the unit during operation, stop all use. Have the welder
inspected and repaired by a qualified service technician.
6. Store the welder and accessories in a clean and dry location.
