1 Safety Guidelines and Precautions
Security Definitions
It indicates that ignoring safety warnings could result in a major accident, or
even death or serious injury.
It indicates that ignoring safety warnings could result in minor injuries or
property damage.
It indicates that ignoring safety warnings could result in equipment failure or
damage.
Personal Protection Precautions
The installation, operation, maintenance and repair of the power source must be
carried out by professionals or persons with relevant knowledge and skills.
Personal protective equipment (PPE), such as protective masks, overalls,
insulating gloves and insulating shoes, should be worn when working.
Keep fire extinguishing equipment at a handy location in the workshop.
Repair or replace defective cables immediately.
Never watch the arc except through lenses of the correct shade.
Supervisors shall be provided for working in high altitude or narrow places, such as
boxes, boilers, cabins, etc.
In confined spaces, adequate ventilation and constant observation are essential.
Those who use cardiac pacemakers shall not approach the power source in use
and welding workplaces without the permission of a physician.
The power source shall not be used for pipeline thawing, battery load or
motor start-up.

Operational Safety Guidelines
Electrical Shock
Grounded all working materials.
Never touch ‘live’ electrical parts.
Always repair or replace worn or damaged parts.
Wearing dry insulated boots, and dry leather gloves.
Disconnect power source before performing any maintenance or service.
Never changing electrodes with bare hands or wet gloves.
Never cooling electrode holders in water.
Never hold the electrode and holder under your arm.
Never work in moist or damp areas. If necessary, the floor near the operating table
must be covered with rubber insulation pad.
Fumes and Gases
You must always have enough ventilation in confined spaces. Be alert to this at all
times.
Fumes from the welding of some metals could have an adverse effect on your
health. Don’t breathe them in. If you are welding on material such as stainless steel,
nickel, nickel alloys or galvanised steel, further precautions are necessary.
Keep your head out of the fumes rising from the arc.
If necessary, use forced ventilation or local exhaust to remove fumes.
Wear a respirator when natural or forced ventilation is insufficient.
4
Welding sparks can cause fire or explosion
Do not carry out welding operations in degreasing, cleaning and spraying areas.
Do not weld/cut gas-filled pipes, sealing grooves (boxes) and other devices,
otherwise explosions or fires are likely to occur.
Do not weld/cut near flammable gases or devices with flammable substances,
otherwise explosion or fire may occur.
When not welded, make sure that any component in the wire circuit does not
contact the workpiece or the earth, otherwise it may cause overheating and fire.
When the welding operation is stopped, remove the electrode in the welding pliers
or cut off the welding wire in the nozzle of the torch.
Arc rays can burn eyes and injure skin
Wear hat and safety glasses. Use ear protection and button shirt collar. Use
welding helmet with correct hade of filter.
Protective barriers are set around the welding site to prevent arc or welding spatter
from injuring others.
Electric and Magnetic Fields
Those who use cardiac pacemakers shall not approach the power source in use
and welding workplaces without the permission of a physician.
It is strictly forbidden to place or wrap welded cables around the body.
Do not place the body between the welding wire and the workpiece cable. If the
welding wire cable is on the right side of the body, the workpiece cable should also
be on the right side of the body.
5
Noise produced during welding can easily cause hearing loss
In order to avoid the harm of noise to you and others, please wear the prescribed
protective equipment.
Matters needing attention in hoisting
The power source with strap or hand is prohibited from using strap or hand for
lifting.
When lifting power source with lifting forklift truck, in order to prevent dumping,
please fork-fit and fix it from side.
When lifting power source with crane, the cable should be tied to the suspension
ring, and the angle between the cable and the vertical direction should not exceed
15 degrees.
When the power source with cylinder and wire feeder is hoisted, the two
equipments should be unloaded from the power supply first. When moving the
power source on the ground, it is necessary to fix the cylinder with a strap or chain
to prevent dumping and injuring people.
If the wire feeder is hoisted by lifting lugs for welding, it is necessary to ensure that
it is firm and insulated.
STOP
PLEASE NOTE that under no circumstances should any equipment or parts be altered or
changed in any way from the standard specification without written permission given by
our company. To do so, will void the Equipment Warranty.

2 Overview
2.1 Product Introduction
This series of welding machines adopts digital inverter technology to convert the
current of 50/60Hz frequency into stable welding output current, and adopts Pulse
Width Modulation (PWM) technology to obtain constant current characteristics and
excellent welding process effect.
This series of welding machines can be used for welding carbon steel/stainless steel
and other materials,its features are as follows:
Wire feeding speed is stable.
Small volume and light weight.
High efficiency and energy saving.
It is easy to start arc, stable welding process and good forming.
It is easy to install and operate.
Equipped with voltage compensation device, when the input voltage changes
within 15% of the rated voltage, it can continue to work.
2.2 Application Area
This series of welding machine is suitable for automobile and accessories industry,
shipbuilding industry, steel structure engineering (construction site), equipment
manufacturing and rail transit, boiler, interior decoration and other fields.
Radio interference may occur when using indoors, so the user
should take adequate preventive measures.

3 Installation
3.1 Installation for MIG (self-shielded) welding
The welding equipment is equipped with power voltage compensation device. It keeps
the machine work normally when power voltage fluctuating ±15% of rated voltage.
When using long cable, in order to reduce voltage drop, big section cable is suggested.
If the cable is too long, it will affect the performance of arcing and other system function,
it is suggested to use the recommend length.
