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 change electrodes with bare hands or wet gloves.
Never cool 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 thisatall
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 flash can burn eyes and injure skin
Make sure you’re wearing a helmet or safety glasses, gloves, welding jackets to
protect yourself.
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
Manual Metal Arc welding is the proces
s
of joining metals where an electric arc i
s
struck between the metal to be welde
d
(workpiece) and a flux-coated filler wir
e
(the electrode). The heat of the arc melt
s
the parent metal and the electrode whic
h
mix together to form, on cooling,
a
continuous solid mass.
The welding power source can offer stronger, more concentrated and more stable arc.
When stick and work piece get short, its response will be quicker. It means that it is
easier to design into welding machine with different dynamic characteristics, and it
even can be adjusted for specialty to make arc softer or harder.
MMA welding machine has the following characteristics: effective, power saving,
compact, stable arc, good welding pool, high no-load voltage, and good capacity of
force compensation. It can weld stainless steel, alloy steel, carbon steel, copper and
other color metal. It can apply to electrodes of different specifications and materials,
including acidity, and alkalescence. It can apply in high altitude, the open air and inside
and outside decoration. Compared with the same products of home and abroad,itis
compact in volume, light in weight, easy to install and operate.
Thanks for purchasing our product and hope for your precious advice. We will dedicate
to producing the best products and offering the best service.

3Installation
3.1 Install the Output Cable
There are two welding methods for MMA welding, please choose according to the
actual needs.
Direct Current Electrode Negative (DCEN): The positive output terminal is connected
to the workpiece, and the negative output terminal is connected to the electrode holder.
The DCEN is suitable for acid electrodes.
Direct Current Electrode Positive (DCEP): The positive output terminal is connected
to the electrode holder, and the negative output terminal is connected to the workpiece.
The DCEP is suitable for basic electrodes.
3.2 Install Accessories - braces (optional)
Note: Some machines can be equipped with braces. Please refer to the following figure
