Operation

Caution: Before arc welding, read and understand all safety precautions and warnings

listed on pages 2 through 5.

1. Determine whether AC or DC welding is to be used.

2. Connect the Ground Cable (3) andTorch Cable (2) to the Arc Welder, as shown in the

photo on the next page, for either AC or DC operation.

Remove the connector knob and place the cable over each terminal and tighten the

connector knob completely.

3. Securely clamp the Ground Cable Clamp (3) as close as possible to the metal object to

be welded, or to the metal work bench where the object is mounted and electrically

connected.

4. Place the desired welding electrode rod securely into the jaws of the Torch Cable

Clamp (2).

If an extension cord is used, it must have the following wire size: up to 30 feet, use 10

AWG size wire;30 to 50 feet, use 8 AWG wire;Over 50 feet, use 6 AWG wire.

7. While holding the Torch Cable Clamp with electrode clearly out of the way of any

grounded objects, turn the Power Switch to the ON position.

8. Orient yourself on the area to be welded, then place the Face Shield over your eyes.

Warning: Never look at the ignited arc without ANSI approved, arc shaded, eye protec-

tion in a full face shield.Permanent eye damage or blindness can occur.Skin burns can

occur. Never breath arc fumes.

9. Stroke the area to be welded with the electrode to ignite the arc.

Never tap the electrode 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 forward at an angle of approximately 30° and

hold it at a distance from the welding object equal to the diameter of the electrode.

Note: If too much current is drawn from the Arc Welder, the Thermal Overload protector will

activate, the amber indicator will light, and the Arc Welder will turn off until it cools down.If this

happens, turn the Power Switch to the OFF position and wait about 20 minutes.

11. When the weld is complete, lift the electrode clearly away from any grounded object,

set the Face Shield down and turn toward the Arc Welder and turn the Power Switch to

the OFF position.

12. Remove the electrode from the Torch Cable Clamp.

13. Unplug the Power Cord from the electrical outlet.
