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.

DRY WORKING PLACE. DO NOT WELD IN PLACES WITH HIGH HUMIDITY.
FOR THE POWER EXTENSION CORD, PLEASE MAKE SURE THE WIRE GAUGE IS MORE
THAN 11 GAUGE AT 220VAC AND 13 GAUGE AT 110VAC. USING A NON-METALLIC
CHAIR PLACED ON A RUBBER MAT WHILE WELDING IS RECOMMENDED. USE 20 AMPS
CIRCUIT BREAKER FOR 110VAC AND 30 AMPS CIRCUIT BREAKER FOR 220VAC. DO NOT
USE TRIPLE PHASE, INSTEAD USE SINGLE PHASE POWER.

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 handl;es must be kept clean, dry, and free from
oil and grase 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.

 ELECTROMAGNETIC FIELDS may be dangerous

 The EMF field that is generated during arc welding may interfere with

various electrical and electronic devices such as cardiac pacemakers.

 Anyone using such devices should consult with their physician prior to

performing any electric welding operations.

 Exposure to EMF fields while welding may have other health effects, which

are not known.

 ELECTRIC SHOCK can be fatal

 Read all precautions described in this manual to reduce the possibility of

electric shock.
 Improper use of an electric welder can lead to electric shock, injury, and
death!

 The power switch should be in the OFF (“0”) position when installing

the work cable and gun and while plugging in the power cord.

 The machine must be securely grounded. Ground the work metal to be welded to a good

electrical (earth) ground. Always attach the ground clamp to the piece to be welded and as
close to the weld area as possible. This will give the least resistance and best weld.

 Maintain the welding torch, work clamp, power cable and welding machine in good, safe

operating condition. Replace damaged insulation.

 Always wear dry, protective clothing and leather welding gloves and insulated footwear. You

have to the wear the welding gloves and auto-darkening welding helmet to protect your hands
and eyes from the harmful arc. Please check www.uwelding.com for proper tig welding
helmet.

 Always operate the welder in a clean, dry, well-ventilated area. Do not operate the welder in

humid, wet, rainy or poorly ventilated areas.

 Do NOT touch the torch head when the button is depressed. It will cause a serious shock and

burn.

 The electrode and work (or ground) circuits are electrically “hot” when the welder is on. Do

not touch these “hot” parts with your bare skin or clothing.

 Due to high frequency, keep all cell phone, cameras, and other electronic devices at least 7

feet away from the machine and torch.
