1. Safety
Welding may damage your body or others, so please take protection measure in
operation.
Only ones who are trained professionally can install, operate, maintain and
repair the equipment.
Do not maintain and repair the machine when the machine is connected with
power.
Electric shock can kill.
Never touch electrical parts.
Wear dry, hole-free gloves and clothes to insulate yourself.
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.
Ensure to install the equipment correctly and ground the work or metal to be
welded to a good electrical (earth) ground according the operation manual.
Ensure to operate the equipment in safe position.
Fumes and gasses can be dangerous!
Welding may produce fumes and gases hazardous to health. Avoid breathing
these fumes and gases. When welding, keep your head out the fume.
Using enough ventilation and/or exhaust at the arc to keep fumes and gases
away from the breathing zone.
Welding sparks can cause fire or explosion.
Remove fire hazards from the welding area. If this is not possible, cover them
to prevent the welding sparks from starting a fire. Remember that welding
sparks and not materials from welding can easily go through small cracks and
openings to adjacent areas.
Do not weld enclosed tanks or containers.
Prohibit to use welder to unfrozen.
Have a fire extinguisher readily available.
Hot parts can lead to burn.
Do not touch the hot parts.
Please use the torch after cooling or use the welding blow lamp.
The people with heart-pacemaker should be away from the welding arc.
Rotating parts may be dangerous.
Far away from rotating parts. (Like fan)
Keep the parts of machine in the safe position.

2. Summary
180DS welder is a MMA arc welder which adopts the insulated gate bipolar transistor
(IGBT) power module.
It can change work frequency to medium frequency so as to replace the traditional
hulking work frequency transformer with the cabinet medium frequency transformer.
Thus, it is characterized with portable, small size, light weight, low consumption and
noise etc.
180DS has excellent performance: constant current output makes welding arc more
stable; fast dynamic response speed reduces the impact form the arc length
fluctuation to the current.
There are also some automatic protection functions for under voltage, over current,
over heat, etc. inside the welders, when the problems listed before occurred, the
alarm on the front panel is light and at the same time the output current will be cut off.
It can self-protect and prolong the using life and greatly improved the reliability of the
welders.
180DS can be used easily, also with little spatter and good weld bead.
180DS is widely used in Petroleum, chemical, mechanical, shipbuilding, architecture,
boiler, pressure container, defence industry and installation and so on. This machine
has high duty cycle even in the 40
℃
, which can keep the continuous operation. Which
can keep working under high temperature and corrosion environment.

6. Installation & Adjustment
Note: Please follow steps in strictly accordance with installation!
Turn Off power at Mains power point!
The equipment protection level is IP21s. Do not use it in the rain!
6.1 Installation
(1) Connect machine to 15 amp 240v power outlet.
(2) Ensure Power Point is in good condition.
(3) With a multi meter measure the input voltage is within the fluctuation range.
(4) Ensure Ground Cable is fitted securely to the front panel.
(5) Ensure Electrode lead is fitted securely to front panel.
(6) Ensure Earth is well attached and grounded to the job.
Above (4) and (5) for the DC reverse method. Operator also on the base metal and
welding rod to choose DCSP method. In general, the basic electrode reverse method
is recommended (ie, connected to the positive electrode).
6.2 Operation
(1) To operate the machine, turn the power switch, so that the power switch is in the
“ON” position, then the power indicator light & fan comes on, the device is ready to
use.
(2) Please note, choose correct polarity selection based on the electrodes to be used.
(3) Ensure Welding leads are kept in good condition, damaged leads or earth clamp
can affect weld performance.

7. Operation Notices
7.1 Installation
(1)Welding environmental temperature should be between -10
℃
to 40
℃
.
(2)Welding should be done in relatively dry environments, with air humidity of not
more than 90%.
(3) Avoid areas containing dust or corrosive gas whilst welding.
(4) Avoid sunlight or rain, do not let water or rain infiltrate the welding machine.
7.2 Safety
When the Welding machine has encountered over-voltage, over current and over
temperature protection circuit, when the primary voltage, output current and the internal
temperature exceeds the set temperature, the welding machine will automatically stop
working; so you need to note the following:
(1) To ensure good ventilation!
The machine is equipped with internal cooling fan ensure that there is adequate air flow
around the machine.
(2) Do not exceed duty Cycle!
Operators should ensure to use the machine within its normal range of operation,
continually putting the machine in overload will reduce life of the equipment in the longer
term.
(3) Ensure machine is connected to correct voltage!
The machine should only be connected to 15Amp 240v Power supply

8. Maintenance
The following operations require the operator has sufficient electrical expertise and
comprehensive Safety knowledge, precaution should be used when opening the
machine case as electrical parts are LIVE!!
(1) Periodic inspection of welding internal circuit connections, make sure
connections are correct and have good connection, (especially the joints or
components). If any rust clean off rust layer and the oxide film, reconnect, and
tighten.
(2) Do not allow hands, hair and tools near live components inside the machine,
such as: fans, so as not to hurt or cause damage to the person or machine.
(3) Regularly with a clean dry compressed air to clean dust from the machine,
compressed air pressure should be at reasonable levels in order to avoid
damage to the welding components inside.
(4) Avoid water or water vapor entering into the welding machine, if there is such a
case, the internal welding machine should be dried. & tested by an authorized
repairer prior to use
(5) Regular inspections for damage of the welding cable, if any, replace the cable.
(6) If not using welding machine, welding machine should be back in the box and
kept in a dry environment.

be replaced.
2. faulty connections, such as lead plugs to
be checked.
Power indicator light on & fan operating with
no welding output.
1. Check all connections inside the
machine.
circuit output connections is faulty.
2. the alarm indicator light
(1)that access to protected status
because of overheating, in which case,
To ma in t a i n p o w e r, so t h a t t h e
temperature dropped to the machine fan
Reasonable temperature, until light goes
out, you can continue working;
(2)Check the thermal switch is damaged,
such damage, to be Replaced
Earth Clamp overheating
