sparks which may ignite the dust or fumes. Keep bystanders, children, and visitors away while operating welding equip- ment. Distractions can cause you to lose control. Protect others in the work area from arc rays, sparks, and slag. Provide barriers or shields as needed. ELECTRICAL SAFETY Grounded welding equipment must be plugged into an outlet properly installed and grounded in accordance with all codes and ordinances. - Page 4 Dress properly. Do not wear loose clothing or jewelry. Contain long hair. Keep your hair, clothing, and gloves away from hot or moving parts. Loose clothes, jewelry, or long hair can be caught in hot or moving parts. (See page 5, number 3, for recommended safety clothing.) Avoid accidental starting.

Page 5: Specific Safety Rules
Maintain welding equipment with care. Keep equipment clean and dry. Properly maintained equipment is less likely to malfunction and is easier to control. Do not use damaged welding equipment. Tag damaged equipment “Do not use” until repaired. Check for misalignment or binding of moving parts, breakage of parts, and any other condition that may affect the equipment’s operation. - Page 6 to protect head and neck. Use aprons, cape, sleeves and shoulder covers, and bibs designed and approved for welding procedures. When welding overhead or in confined spaces, wear flame resistant ear plugs or ear muffs to keep sparks out of ears. Avoid overexposure to fumes and gases.
- Page 7 materials. If relocation is not possible, protect the combustibles with a cover made of fire resistant material. Remove or make safe all combustible materials for a radius of 35 feet (10 meters) around the work area. Use a fire resistant material to cover or block all open doorways, windows, cracks, and other openings.
- Page 8 Do not touch the welding wire if you are in contact with the workpiece, ground, or another welding wire from a different machine. Do not allow the welding wire to touch earth ground. Accidental earth discharges may cause overheating and fire hazards. Do not pass equipment cables through or near lifting chains, crane cables, or any electrical lines.

must be the only wire connected to the equipment’s grounding system and must never be attached to an electrically “live” terminal. (See Figure A.) Your welding equipment must be plugged into an appropriate outlet, properly installed and grounded in accordance with all codes and ordinances. The plug and outlet should look like those in the following illustration. -
Page 11: Extension Cords
EXTENSION CORDS Grounded welding equipment requires a three wire extension cord. Double Insulated welding equipment can use either a two or three wire extension cord. As the distance from the supply outlet increases, you must use a heavier gauge extension cord. Using extension cords with inadequately sized wire causes a serious drop in voltage, resulting in loss of power and possible tool damage. -

This Welder, at its 10% at 55 AMPs duty cycle (low), can run continuously under load for 1 minute out of each 10 minute period. After using continuously for one minute, the Welder must sit unused for 9 minutes. At its 6% at 70 AMPs duty cycle (high), the Welder can run continuously under load for 36 seconds out of each 10 minute period.
- Page 17 Insert the bare end of an AC Electrode (not included) securely in the Electrode Holder (27). (See Figure I.) While holding the Electrode Holder (27) with its Electrode clearly out of the way of any grounded objects, turn the Power Switch ON/OFF (9A) to its “ON” position.
- Page 18 EXAMPLE OF A PROPER WELD Typically, three factors which most affect the quality of a weld are as follows: (A) The speed at which you advance along the weld. (B) The length of arc. (C) The rate of amperes at which you are welding. Adjusting one or more of these three factors can help increase the quality of weld.
