SAFETY WARNINGS AND PRECAUTIONS

PLEASE READ AND UNDERSTAND THE FOLLOWING SAFETY HIGHLIGHTS.

BE SURE THAT ALL INSTALLATION, OPERATION, MAINTENANCE AND REPAIR

PROCEDURES ARE PERFORMED ONLY BY QUALIFIED INDIVIDUALS. ARC AND TIG
WELDING CAN BE HAZARDOUS. PROTECT YOURSELF AND OTHERS FROM POSSIBLE
SERIOUS INJURY OR DEATH. KEEP CHILDREN AWAY. PACEMAKER WEARERS SHOULD

CONSULT WITH THEIR DOCTOR BEFORE OPERATING.

WHEN USING THE WELDER, ALL BASIC SAFETY PRECAUTIONS SHOULD ALWAYS BE

FOLLOWED TO REDUCE THE RISK OF PERSONAL INJURY AND DAMAGE TO EQUIPMENT.

READ ALL INSTRUCTIONS BEFORE USING THIS WELDER.

Keep work area clean. Cluttered areas invite injuries.

Observe work area conditions. Do not use machines or power tools in damp or wet locations. Do not

expose to rain. Keep work area well-lighted. Do not use electrically powered tools in the presence of

flammable gases or liquids.

Keep children away. Children must be never be allowed in the work area. Do not let them handle

machines, tools or extension cords.

Store idol equipment. When not in use, tools must be stored in a dry location to inhibit rust. Always

lock up tools and keep them out of the reach of children.

Do not force tool. It will do the job better and safer at the rate for which it was intended. Do not use

inappropriate attachments in an attempt to exceed the tool capacity.

Use the right tool for the job. Do not attempt to force a small tool or attachment to do the work of a

larger industrial tool. There are certain applications for which this welder was designed. Do not modify this

welder and do not use this welder for any other purposes for which it was not intended.

Dress properly. Do not wear loose clothing or jewelry as they can be caught in moving parts.

Protective, flame retardant, electrically non-conductive clothing and non-skid footwear are recommended

when working. Wear restrictive hair covering to contain long hair.

Use eye and ear protection. Always wear ANSI approved, arc shaded, impact safety face shield
(welding helmet). Always use a full-face shield when welding. Always wear ANSI approved eyewear under
face shield and while in the workplace. Wear a NIOSH approved dust mask or respirator when working

around metal, chemical dusts, fumes and mists.

Do not over reach. Keep proper footing and balance at all times. Do not reach over or across running

machines.

Maintain tools with care. Keep tools sharp and clean for better and safer performance. Follow
instructions for lubricating and changing accessories. Inspect tool cords periodically and, if damaged, have
them repaired by an authorized technician. The handles must be kept clean, dry, and free from oil and grease

at all times.

Disconnect power. Unplug tool when not in use.

Remove adjusting keys and wrenches. Check that keys and adjustment wrenches are removed from

the welder and work area before plugging in.

Avoid starting unintentionally. Be sure the switch is in the off position when not in use and before

plugging in. Do not carry any tool with your finger on the trigger, whether it is plugged in or not.

Stay alert. Watch what you are doing. Use common sense. Do not operate any tool when tired.

Check for damaged parts. Before using any tool, any part that appears damaged should be carefully

checked to determine that it would operate properly and perform its intended function. Check for alignment
and binding of moving parts; any broken parts or mounting fixtures; and any other condition that may affect
proper operation. Any part that is damaged should be properly repaired or replaced by a qualified technician.

Do not use the tool if any switch does not turn on and off properly.

Guard against electric shock. Prevent body contact with grounded surfaces such as pipes, radiators,

ranges, and refrigerator enclosures.

Replacement parts and accessories. When servicing, use only identical replacement parts. Use of
any other parts will void warranty. Only use accessories intended for use with this welder. Approved

accessories are available from www.uwelding.com.

Do not operate tool if under the influence of alcohol or drugs. Read warning labels on prescriptions
to determine if your judgment or reflexes are impaired while taking drugs. If there is any doubt, do not

operate the welder.

Maintenance. For your safety, service and maintenance should be performed regularly by a qualified

technician.

Use proper size and type extension cord. If an extension cord is required, it must be of the proper
size and type to supply the correct current to the welder without heating up. Otherwise, the extension cord
could melt and catch fire, or cause electrical damage to the welder. This welder requires use of an extension
cord of 20 amps minimum capability up to 30 feet, with a wire size rated at 12 AWG. Longer extension
cords require larger size wire. If you are using the welder outdoors, use an extension cord rated for outdoor
use, signified by “WA” on the jacket. Performance of this welder may vary depending on condition in local

line voltage. Extension cord usage may also affect welder performance.

The warnings, cautions and instructions discussed in this instruction manual cannot cover all possible
conditions and situations that may occur. It must be understood, by the operator, that common sense and

caution are factors, which cannot be built into this product, but must be supplied by the operator.
ARC WELDER SAFETY WARNINGS AND PRECAUTIONS

Warning: This product, when used for welding and similar applications, produces chemicals to cause

cancer and birth defects (or other reproductive harm).

 ELECTRIC SHOCK can be fatal

 The electrode and work (or ground) circuits are electrically “hot” when the machine is

on. Do not touch these “hot” parts with your bare skin or wet clothing. Protective clothing

should be hole free, dry and ANSI approved. Wear dry, hole-free gloves to insulate hands.
 Do not permit electrically live parts, cables, or electrodes to contact skin, clothing or
gloves.

 This unit draws enough current to cause serious injury and or death.

 Before turning the welder on, check the welder gun to be sure that there are no protruding screw heads

and that all insulation is secure.

 Insulate yourself from work and ground using dry insulation. Make certain the insulation is large enough

to cover your full area of physical contact with work and ground.

 Always be sure the work cable makes a good electrical connection with the metal being cut. The

connection should be as close as possible to the area being cut

 Ground the work metal to be cut to a good electrical (earth) ground.
 Maintain the welding torch, work clamp, power cable and cutting machine in good, safe operating

condition. Replace damaged insulation.

 Never dip the electrode in water for cooling.
 When working above floor level, use a safety belt to protect yourself from a fall should you get a shock.
