IMPORTANT SAFETY RULES
COMMON SENSE AND CAUTION ARE FACTORS WHICH CANNOT BE BUILT INTO ANY PRODUCT.
THESE FACTORS MUST BE SUPPLIED BY THE OPERATOR.
Keep your work area clean and well lit. Cluttered work benches and dark work areas may cause accidents or
injury.
Do not operate power tools in explosive areas, such as in the presence of flammable liquids, gases or
dust. Power tools create sparks which may ignite the dust or fumes.
Keep bystanders, children and visitors away while operating a power tool. Distractions can cause you to
lose control.
Wash hands after handling the cord. Touching the cords could expose you to lead, which is known in the
State of California to cause cancer, birth defects and other reproductive harm.
Keep children, and other distractions at a distance while operating power tools.

Double insulated tools are equipped with a polarized plug (one blade is wider than the other.) This plug
will fit in a polarized outlet only one way. If the plug does not fit fully in the outlet, reverse the plug. If it
still does not fit, contact a qualified electrician to install a polarized outlet. Do not change the plug in
any way. Double insulation eliminates the need for the three wire grounded power cord and grounded power
supply system.
Avoid body contact with grounded surfaces such as pipes, radiators, ranges and refrigerators. There is
an increased risk of electric shock if your body is grounded.
Do not abuse the cord. Never use the cord to carry the tool or pull the plug from an outlet. Keep the
cord away from heat, oil, sharp edges, or moving parts. Replace damaged cords immediately. Damaged
cords increase the risk of electric shock.
When operating the tool outside, use an outdoor extension cord marked “WA” or “W.” These cords are
rated for outdoor use and reduce the risk of electric shock. Make sure the extension cord being used is in good
condition. If there are any cuts or nicks (no matter how deep) in the insulation, DO NOT use that cord. Also,
make sure the extension cord is heavy enough to carry the current needed. DO NOT use small "around-thehouse” lamp extension cords. These cords can easily overheat and/or catch fire when used with power tools.
Do not force tool. Use the correct tool for your application. The correct tool will do the job better and safer
at the rate for which it is designed.
Do not use the tool if the power switch does not turn it “ON” or “OFF”. Any tool that cannot be controlled
with the switch is dangerous and must be repaired.
Disconnect the power cord plug from the power source before making any adjustments, changing
accessories or storing the tool. Such preventive safety measures reduce the risk of starting the tool
accidentally.
People with pacemakers or other electronic devices should consult with a physician before operating
this product. Interruption or failure of the pacemaker could occur when electrical equipment is operated within
close proximity of electrical devices.
All work areas should be clean and well lit. Accidents are more likely to occur in poorly lit and cluttered
areas.
Keep the power cord in good condition, and replace damaged cords immediately. Do not use the cord to
pull the plug from the outlet. Keep the cord away from materials and surfaces that could damage cords. The
risk of electric shock increases when the power cord is damaged.
Always use the appropriate extension cord, making sure it is rated for use with power tools. Always be
sure the extension cords are in good condition, free of cuts or nicks in the insulation. If using the power tool in
an outside area with an extension cord, make sure the cord is rated for outdoor use.

OPERATION
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 breathe arc fumes.
Good welding requires a high degree of skill and experience. You should practice a few sample welds on
scrap metal before you begin welding your first project. Additional practice periods are recommended
whenever you weld a different thickness of material, wire, or weld a different type of connection.
1. Attach the Handle to the top of the Arc Welding Unit using the handle screws.
2. Connect an appropriate 220 VAC electrical plug to the line cord. This should be done by a licensec electrician.
3. Place each wheel over the axle and insert the wheel hub.
4. Attach the front foot to the bottom of the Welder using the supplied hardware. Snap the Handle into the Face Shield.
5. Make sure this unit is only for AC Welding.
6. Securely clamp the ground cable clamp 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.
7. Place the desired welding elecrode rod securely into the jaws of the Torch Cable clamp.
8. While viewing the Current Setting gauge, turn the Current Control knob to the correct current setting for the
electrode rod being used.
9. Verify that the Power Switch is in the off position, then plug the Welder 220 VAC plug into a dedicated, 40 amp line
with delayed action type circuit breaker for fuses.
10. 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.
11. Place the face shield over your eyes. Never look at the ignited arc without ANSI approved arc shaded eye
protection/face shield. Permanent eye damage or blindness can occur. Skin burns can occur. Never breath arc fumes.
12. 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.
13. Once the arc is ignited, tilt the electrode forward at an angle of approximately 30 degrees 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.
14. 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.
15. Remove the electrode from the torch cable clamp.
16. Unplug the power cord from the electrical outlet.
Avoid damage to the Welder by not leaving the unit on for more than the prescribed duty cycle time.
The duty cycle defines the number of minutes, within a 10 minute period, during which a given Welder can safely
produce a particular welding current. For example, this Welder has a 10% duty cycle at 160 Amps.
AWELD160 ARC Welder Assembly & Operating Instructions
8
Failure to carefully observe duty cycle limitations can easily over stress a Welder’s power generation system,
contributing to premature Welder failure.
This Welder is equipped with an internal thermal protection system to help prevent over stressing the unit. When the
unit overheats, it automatically shuts down, then automatically returns to service when it cools down.
Note: Once the unit returns to service, follow a more conservative duty cycle routine to help prevent excess wear to
the Welder.
TROUBLESHOOTING
MAINTENANCE
Disconnect the power supply before cleaning. Wear safety eyewear before cleaning. Used compressed dry
air to blow off dust and debris. Use a soft bristle brush if compressed air is not available.
Applying excessive force can overload the welder, decrease the life and increase the wear on the tool.
Some chemicals can damage the product. Do not use harsh chemicals such as gasoline, carbon
tetrachloride, paint thinner, etc.
A qualified repair technician must perform any tool service or repair. Service or maintenance performed by
unqualified personnel could result in injury. Use only identical replacement parts. Use of unauthorized parts or
failure to follow maintenance instructions may create a risk of electric shock or injury.
ACCESSORIES
Use only accessories that are recommended by the manufacturer for your model. Accessories that may be
suitable for one tool may become hazardous when used on another tool.
Always attach grounded (3-prong) extension cords to grounded (3-prong) outlets.
If you must use an extension cord, be sure that the gauge is large enough to carry the amount of current
necessary for your power tool. If not, your tool may experience a loss of power, excessive voltage drop or
overheating. For example, the smaller the gauge number, the heavier the cord.
