PRECAUTIONS AND SAFE USE
Welding may result in injury to you and others, so please
implement proper protections and precautions when welding.
Electric shock-may result in serious injury or
even death!
Ensure devices are properly grounded.
Do not touch live parts with naked skin, wet
gloves or wet clothes.
Be sure you are insulated from the ground and
workpiece.
Confirm the safety of your working position.
Smoke may be harmful to your health!
Keep your head away from fumes and smoke
to avoid inhalation of waste gas while welding.
When welding, keep the working environment
well-ventilated with exhaust or ventilation
equipment.
Arc radiation may hurt your eyes and burn
your skin!
Use a proper welding mask and wear
protective clothing to protect your eyes and
body.
Ensure onlookers have a proper mask or
curtain to avoid injury.
Improper use and operation may result in fire
or explosion.
Welding sparks may cause fires, please
ensure there are no flammables near the
welding are and pay attention to fire safety.
Ensure there is a fire extinguisher nearby, and
make sure someone has been trained to
operate the fire extinguisher.
Do not weld in a closed unventilated container.
Do not use this machine for pipe thawing.
Hot workpieces can cause severe scalds or
burns.
Do not touch the workpiece(s) with bare
hands.
If continuously working, periodically cool the
welding torch to avoid overheating the tip.

Excessive noise can be harmful to people’s
hearing.
Wear proper hearing protection when welding.
Ensure onlookers have a proper hearing
protection or distance to avoid injury.
Magnetic field can impair cardiac pacemaker
operation.
People with a cardiac pacemaker should
consult their physician prior to attempting to
use welding equipment.
Moving parts may injure your body.
Please keep away from moving parts (like
fan).
Each door, panel, cover, baffle plate, and
protective device the like should be closed and
located correctly.
Seek professional support with operating
issues.
When an issue arises with the installation and
operation or the unit, please refer to the
operating manual before attempting repairs.
If the issue persists, or you still cannot solve
the problem, please contact the dealer to
obtain professional support.
Working Environment
Prior to welding, properly inspect the work area for potential
hazards before starting any welding operations.
1) Welding should be carried out in a dry environment with
humidity below 90%.
2) The temperature of the work area should be between 14⁰F
and 104⁰F.
3) Avoid welding in sunlight and rain. Keep everything dry at
all times.
4) Avoid welding in dusty areas or environment with corrosive
chemical gas.
5) Arc welding should be operated in an environment without
strong airflow.
6) Weld in a well-ventilated area or use proper ventilation
systems to remove harmful fumes and gases.

Safety Tips and Recommendations
This unit is equipped with an over-current/over-voltage/over-
heating protection circuit. When the supplied voltage, output
current or inner temperature exceeds these limits, the unit will
stop automatically. Please check those conditions prior to
restarting. WARNING: excessive use of the unit with these
conditions will lead to welder damage.
1. Ventilation
1.1. This welder will create powerful electrical currents that
require the unit to have constant cooling.
1.2. The internal fans are critical to ensuring proper and
effective cooling of the machine.
1.3. The operator must ensure that the louvers are
uncovered and unblocked for proper airflow.
1.4. The minimum distance between the unit and nearby
objects should be 76 inches.
1.5. Good ventilation is of critical importance for optimum
performance and longer lifespan of the unit.
2. Overload Operation
2.1. Remember to operate the welder within the allowable
duty cycle (refer to the corresponding duty cycle).
2.2. Ensure that the welding current does not exceed the
max load current.
2.3. Overload could obviously shorten the machine's
lifespan, or even damage the machine.
3. Exceeding Recommended Voltage
3.1. Verify the power supply voltage range of the unit, please
refer to “Technical Parameters” table.
3.2. This unit is equipped with automatic voltage
compensation, which enables it to maintain a voltage
range within the allowable supply ranges.
3.3. Power supply voltage that exceeds the recommended
levels may lead to damaging the components of the unit.

Safety Tips and Recommendations
4. Fault/Halt Indicator
4.1. A sudden halt may occur and the red indicator on the
front panel is lit.
4.2. The welder has exceeded the standard duty cycle which
triggers temperature alert due to overheating.
4.3. Should this occur, halt the welding operations and allow
the unit to cool down. Do not turn off the power and keep
the cooling fan operating to reduce the unit temperature.
4.4. Welding can be resumed after the unit temperature falls
back to the standard operating range and the red
indicator is off.

Welding Fundamentals
Welding is a relatively simple process for bonding two pieces of
metal together. As an example, soldering two wires together is
the same concept. To connect the wires, we use heat to melt
solder onto the wires to create the connection and a permanent
bond and circuit.
The welding process utilizes a very strong electrical current that
creates enormous heat that literally melts the two pieces
together, and a consumable rod (ARC Welder) or wire (MIG
Welder) is melted into the joint and creates a strong metallic
bond between the two pieces.
The Handheld 120 is the latest evolution, if not revolution in
welder design utilizing IGBT (Insulated-Gate Bipolar Transistor)
technology that reduces the power demands while generating
sufficient energy to create welds.
The handheld design is clean, simple and easy to use. As with
any ARC welder (Stick Welder) a consumable electrode
conducts current to the pieces, as well as the bonding material to
create the weld. This type of welder is perhaps the easiest to
use, as it is somewhat of a point-and-shoot type of welder
suitable for hobbyists and even professionals.
There is a slight learning curve and experimentation as to the
welding voltage and the electrode type (charts are provided at
the end of this document). We recommend starting with an E-
6013 general purpose welding rod which is ideal for most
shallow welding needs.
The Handheld 120 will work with nearly all generally available
electrodes; however, some electrodes may require reversed
polarities and the larger diameter / demand electrodes may
exceed the holder capacity and power delivery of this unit.
