3. Turn the Power Switch ON.
The Operation interface will light up and the Cooling fan will
rotate.
NOTE:Welder is now energized and open circuit Voltage is
present.
4. Select MMA
5. Stroke the workpiece lightly to ignite the arc.
Tips for igniting the arc:
a. Tap the surface with the Electrode.
b. Stroke the surface with the Electrode.
c. Strike the surface like a match with the Electrode.
6. After the arc ignites:
a. Lift the Electrode off workpiece the same distance as the diameter of the bare metal end.
b. Tilt Electrode back 10 to 20 degrees.
c. Drag Electrode to the back end of the weld puddle to deposit material as needed.
7. The initial settings may need to be adjusted after stopping and carefully inspecting the weld.Proper
welding takes experience.
8. When finished welding; lift the Electrode from the workpiece, then set Electrode Holder down on
nonconductive, nonflammable surface away from any grounded objects.
9. Turn the Power Switch OFF
NOTE:
To prevent accidents, after use:
• Allow Welder to cool down.
• Unplug Welder’s power cord from outlet.
• Remove Ground Clamp.
• Disconnect Electrode Holder and Ground Cables.
10. Clean, then store Welder and its accessories indoors out of children’s reach.
