WARNING!
Welding and cutting is dangerous to the operator, people in or near the working area,
and the surrounding, if the equipment is not correctly operated. Therefore, the perfor-
mance of welding/cutting must only be under the strict and comprehensive obser-
vance of all relevant safety regulations. Please read and understand this instruction
manual carefully before the installation and operation.
• The switching of function modes is possibly damaging to
the equipment, while the welding operation is performed.
• Do disconnect the electrode-holder cable with the
equipment, after the performance of welding.
• A safety switch is necessary to prevent the equipment
from electric-leakage.
• Welding tools should be of high quality.
• Operators should be qualied.
ELECTRIC SHOCK: It may be fatal
• Connect the earth cable according to standard reg-
ulation.
• Avoid all contact with live components of the welding
circuit, electrodes and wires with bare hands. It is nec-
essary for the operator to wear dry welding gloves while
he performs the welding task.
• The operator should keep the working piece insulat-
ing from himself/herself.
Smoke and Gas generated while welding or cutting:
harmful to people’s health.
• Avoid of breathing the smoke and gas of welding or
cutting.
• Keep the working area in good ventilation
Arc light-emission: harmful to people’s eyes and skin
• Wear the welding helmet, anti-radiation glass and
work clothes while the welding operation is performed.
• Measures also should be taken to protect people in or
near the working area.
FIRE HAZARD
• The welding splash may cause fire, thus remove flam-
mable material away from the working place.
• Have a re extinguisher nearby, and have a ted re
person ready to use it.
Noise: Possibly harmful to peoples’ hearing.
• Surface noise is generated while welding/cutting, the
hearing aids is necessary in some cases.
Machine Fault:
• Consult this instruction manual.
• Contact your local dealer or supplier for further advice.

2. Installation
1 TIG welding machines are tted with auxiliary power system, so if 15% of the voltage-
la pipe, it still works.
If you use a long wire to the battery voltage drops, it is recommended to increase the
diameter, but if line too long can cause abnormal operation, so choose the correct
length. Ventilation openings to allow free cooling system to operate.
2 Connect the inert gas source. The system includes a gas cylinder, gas regulator and
gas hose, hose clamps should be tightened, to prevent escape of gas or air from
entering.
3 Motor housing is grounded at least 6mm ² conductors, grounding screw on the back
of the machine over to the grounding system.

3-3. Operation Steps of Pulse TIG Welding
- Connect the welding machine to the input power supply and power the welding
machine on. In such case, power on the machine and let it have a self-check;
and the screen will display: Full display->HYL->Model such as 200-> Enter the
previous welding status.
- Press the TIG/MMA function selector switch, then the pulse TIG indicator will
be on and the welding machine will change into the pulse TIG status.
- Press the parameter setup selector key to set welding parameters such as
foreblow time, arc striking current, rise time, given current, fall time, arc stopping
current, afterblow time, etc; with the regulation knob (2), you may respectively

4-2 . Safety requirements
Welding provides protection against overvoltage / overcurrent / overheating. If any of the
above events occurs, the machine stops automatically. However, over- stress damage to the
machine , keep the following guidelines :
1. Ventilation . When welding a strong current going through the machine , so the machine is
not enough natural ventilation for cooling . The need to ensure adequate cooling, so the
distance between the plane and any object around it at least 30 cm . Good ventilation is
important to normal function and service life of the machine.
2. Continuously , the welding current does not exceed the maximum allowable value. Current
overload may shorten its life or damage to the machine .
3. Surge banned ! Observance of tension range follow the main parameter table . Welding ma-
chine automatically compensates for voltage , allowing the voltage within permissible limits
of law. If input voltages exceed the specied value , damaged parts of the machine .
4. The machine must be grounded! If you are operating in a standard, grounded AC pipeline in
the event of grounding is provided automatically . If you have a generator or foreign , unfa-
miliar , non-grounded power supply using the machine , the machine is required for ground-
ing connection point earth to protect against electric shock .
5. Suddenly stopping may be during welding when an overload occurs or the machine over-
heats . In this case, do not restart the computer , do not try to work with it right away, but do
not turn off the power switch , so you can leave in accordance with the built-in fan to cool
the welding machines .
5. Maintenance
1. Remove power unit before maintenance or repair!
2. Ensure that proper grounding!
3. Make sure that the internal gas and electricity connections are perfect and tighten, adjust if
necessary, if there is oxidation, remove it with sandpaper and then reconnect the cable.
4. Hands, hair, loose clothing should be kept away under electric parts, such as wires, fan.
5. Regularly dust from the machine clean, dry compressed air, a lot of smoke and polluted air to
clean the machine every day!
6. The gas pressure is correct not to damage components of the machine.
7. If water would be, for example. rain, dry it in the machine and check the insulation properly!
Only if everything is all right, go after the welding!
8 When not in use for a long time, in the original packaging in a dry place.
4. Precautions
4-1. Workspace
1. welding equipment free of dust, corrosive gas, non-ammable materials, up to 90% humidity
for use!
2. Avoid welding outdoors unless protected from direct sunlight, rain, snow, work area tempera-
ture must be between -10 ° C and +40 °.
3. Wall to position the device at least 30 inches away.
4. well-ventilated area to perform welding.
