1. SAFETY GUIDANCE
1.1 Precautions for Operations and Installation
Beware of electric shock!
Install grounding devices according to application standard.
Do not touch live parts with naked skin, wet gloves or wet clothes.
Be sure you are insulated from ground and workpiece.
Cover the cover plate of the machine before power on to avoid an electric
shock.
Confirm the safety of your working position.
Beware of fire hazard!
To avoid fire hazard, please install the machine on non-combustible
materials;
To avoid fire hazard, please make sure there are no inflammables nearby.
Beware of explosion!
To avoid explosion, please do not install the machine in an explosive gas
environment.
Smoke-may be harmful to your health!
Keep your head away from the smoke to avoid inhalation of waste gas in
welding.
Keep the working environment well ventilated with exhaust or ventilation
equipment when welding.
Arc radiation-may hurt your eyes and burn your skin!
Use proper mask and wear protective clothing to protect your eyes and body.
Use proper mask or curtain to protect onlooker from being injured.
Magnetic field can make cardiac pacemaker a bit wonky.
People with cardiac pacemaker should consult the doctor before carrying out
welding.
Stay away from the power source to reduce the affect of magnetic filed.
Improper use and operation may result in a fire or an explosion.
Welding spark may result in a fire, so please make ensure there are no
inflammables near the welding position, and pay attention to fire safety.
Ensure there is fire extinguisher nearby, and make sure someone has been
trained to operate the fire extinguisher.
Do not weld closed container.
Do not use this machine for pipe thawing.

Hot workpiece can cause severe scald.
Do not touch hot workpiece with bare hands.
Cool the welding torch for a while after continuously working.
Excessive noise can be harmful to hearing.
Wear ear covers or other hearing protectors when welding.
Give warning to nearby personnel that noise may be potentially hazardous to
hearing.
Moving parts may injure your body.
Please keep away from moving parts (such as fan).
All doors, panel, cover, baffle plate, and other protective device should be closed
and well located.
Asking for professional support while trouble strikes.
When trouble strikes in installation and operation, please resort to this
manual for according contents.
If you are still in lost, or you still cannot solve the problem, please contact the
dealer or the service center for professional support.
Moving the machine can be dangerous.
Please make sure the input power switch is turned off before moving the machine.
Do not stress the operation panel and cover plate while moving the machine so that to avoid falling
items hurting others.
Please fix the wheels tightly while moving the machine with a forklift.
To avoid possible fire hazard or other damages, please do not install and operate this machine if it’s
found damaged or lack of components.
Replacing machine components can be dangerous.
Only qualified personnel can replace the machine components. Make sure there are no foreign
bodies such as wire leads, screws, gaskets and metal bars falling into the machine when replacing
the components.
Make sure the connecting wires inside the machine are correctly connected after replacing the
PCBs, and then the machine can be run. Otherwise, there is a risk of damage to property.

Other Precautions
1) Make sure the place to install the machine can bear the weight of welding machine.
2) Do not install the machine at places where water droplet splash may occur, such as near water
pipes.
3) Welding should be carried out in dry environment with humidity less than 90%.
4) Avoid welding in the open air unless sheltered from sunlight and rain. Keep it dry and do not place it
on wet ground or in puddles.
5) Do not carry out welding with the welding machine placed on a platform with a pitch greater than 10°.
This product is equipped with over current/over voltage/overheating protection circuit. When the mains
voltage, output current or inner temperature exceeds the set standard, the machine will stop
automatically. However, excessive use of machine may also damage the machine; therefore, please pay
attention to the following:
Good ventilation
A working welder will generate big current and has strict cooling requirements that cannot be met
with natural ventilation. Therefore the built-in fan is very important in enabling the machine to work
stable with effective cooling. Operator should make sure that the louvers be uncovered and
unblocked.
Over voltage is forbidden.
This machine is of automatic mains voltage compensation, which ensures that the welding current
varies within the given range. In case that the input mains voltage exceeds the tolerance value, it
would possibly damage the machine; therefore, operators should understand take relevant
precautions in advance.
Overload is forbidden.
Please observe the max load current at any moment (refer to the corresponding duty cycle). Make
sure that welding current not exceeding the maximum load current. Overload could obviously
shorten the machine's lifespan, or even damage the machine.
Suddenly the “E61” code may appear on the digital screen while the machine is of over-load status.
Under this circumstance, it is unnecessary to restart the machine. Keep the built-in fan working to
lower the temperature inside the machine. Welding can be continued after the inner temperature falls
into the standard range and the “E61” code is disappeared.
1.2 Preparation before welding
1) Safety devices
To avoid gas poisoning, suffocation, dust poisoning, please use air discharge equipment as
required and wear respiratory protection devices.
Please wear safety goggles or other protection devices which are of sufficient shading when
welding or guiding welding.

4
To avoid eyes being hurt by spatters, please wear protective goggles.
Please wear welding specialized protective clothing, such as leather protective gloves, long-sleeved
clothes, welding spats, aprons, etc.
Please install protective barrier to protect standbys from hurting by arc light.
Please wear sound insulation devices when noise is too huge.
Please use ventilator for air exchanging; please take anti-wind measures so that to avoid poor
welding performances resulted from direct blowing to arc.
2) Cable connection check
Fix welder—place welders on dry, flat position which is of good ventilation.
Please make sure the correct and tight connection of grounding cable, power input cable, welding cable
and workpiece side cable.
3) Other items’ check
Please check the shielding gas, welding environment, welding torch and make sure they are all in good
condition.
1.3 Precautions for discard
Pay attention to the following when discarding welding machine:
Burning the electrolytic capacitors in the main circuit or on the PCBs may cause an explosion.
Burning the plastic parts such as the front panel may produce poisonous gas.
Dispose it as industrial waste.
2. PRODUCT DESCRIPTION
2.1 Function and Features
TIG welder is of constant current external characteristic. Welding current will not be changed per arc
length but being kept at a very stable level. It adopts PWM technology and high-power switching
element IGBT (discrete) to rectify AC110V/AC220V (50Hz/60Hz) voltage to DC310V, after inverting
it to 45KHz, there is a voltage step-down and rectification again, stable welder current is obtained by
output current feedback and adjustment.
Built-in MCU technology and IGBT inverter Welder, totally digital control, which ensures great and
stable welding performance.
TIG200 is TIG and MMA 2 in 1 Multi-Process welding machine.
MMA/Stick welding features: hot start, arc force and an-stick.
TIG welding features: 2T/4T Operation, current regulation, post-flow adjustable, down-slope.
Fan-On-Demand power source cooling system operates only when needed, reducing noise, energy
use and the amount of contaminants pulled through the machine.
Portable and Lightweight: 11.68lb, carry with handle or shoulder strap.
