INTRODUCTION
Tig180/200 are single process argon-arc welders.
Outer characteristics of this welding machine are continuous current and an arc drive controlling. It has
constant current characteristics: when arc voltage is normal, it guarantees that welding current will not
be changed with arc length. The current will become higher and higher with arc voltage down-slope.
When arc voltage is too low, it will lead to an arc length that will return into normal range. When arc
voltage is too low to support the arc, voltage will down slope immediately in order to protect from
splashing which is caused by a short circuit.
Another arc welding characteristic is the continuous current. The welding current will not change arc
length, so that the current is very stabilizing .When electrode circuit is short, current will declined to 0
automatically in order to protect tungsten and work piece.
This arc welding machine has characteristics as following:
1. High quality
2. Stable arc
3. Molten bath is easy to control
4. o-load voltage is higher
5. Able to be used widely
6. Suitable for job of high-altitude and outdoor and fitment of inside or outside
7. Lightweight
8. Simple installation and operation
Users are not allowed to dismantle or refit or replace electric components by themselves. Other-
wise the manufacturer will not.

EXPLANATION SWITCH
INSTALLATION
When you want to use a longer cable, please choose a cable of bigger section in order to protect volt-
age from stepping down. If torch cable is too long, it maybe affects the function of arc-striking and
other functions of system. Due to this we suggest that the user must the length which is recommended
by manufacturer.
INPUT CABLE CONNECTION
Every welding machine has disposed a power cable which must be connected to corresponding volt-
age in compliance with input voltage. If a single phase 230v DC power cable is connected to 380v AC
power cable by carelessness, it will make the power switch into over-voltage protection position.
Please turn power supply off first and then connect the machine to power of 220v and open it again.
Input voltage must be single phase 230V.
Make sure that power cable is connected to power switch or connector firmly and prevent from oxidiz-
ing. Check if the power voltage is inside waved range.

OUTPUT CABLE CONNECTION
When using argon-arc welders, please connect them as aforementioned. When you use striking, pay
attention as following:
Every machine has a pair of mobile plugs. The cable of welding handle has to be connected to the
black mobile plug, the other terminal of grounding pincer has to be connected to the red mobile plug.
After that they must be tightened. Make sure secondary cables (handle cable and grounding cable)
are connected to the mobile plug reliably.
Insert the mobile plug into the mobile socket and then tighten it. Otherwise the plug and socket will be
burned up if the current is too high or working time is too long.
Pay attention to the electrode of connection cable. There are two methods of connection: positive con-
nection and negative connection. Positive connection is when thework piece is connected to positive
electricity and torch handle is connected to a negative electrode; negative connection is when the work
piece is connected to negative electricity and the torch handle is connected to a positive electrode.

OPERATION
Argon-arc Welding
1. Make sure the power switch is in “on” position and the indicator will be lit.
2. Open the valve of argon cylinder and adjust the volume of flow meter.
3. Inter axial-flow fan will now begin to work. Press the control knob of the torch so that the elec-
tromagnetic valve will start. The user can hear a sound of HF arc-striking, at the same time
the argon will start flowing out of the torch tip.
4. The knob of arc-striking push is used to adjust the welding function, especially in a low cur-
rent range, that is cooperated with knob of welding current adjustment. They may adjust cur-
rent of arc-striking and be out of control of knob of welding current adjustment. So machine
can gain powerful energy and push current can achieve effect that may imitate DC welder re-
volving.
5. The distance from welding tungsten electrode to work piece needs to be 2-4 mm. Then you
need to press the control knob. Burning and striking the arc the sound of HF arc-striking will
be diminished. The welding machine can be operated now.
Striking Description
1. Open the power switch of front control panel so that the fan starts working.
2. Make sure the function switch is on “down” position.
3. Set the welding current adequate to thickness of work piece.
4. Adjust welding characteristic by drive knob.
NOTE: Do not touch any cable and connector when the machine is working, it can cause damage to
health of people or the machine itself.
MAINTENANCE
1. Remove dust by dry and clean compressed air regularly. If welding machine is operating in envi-
ronment with polluted air or smoke, the machine needs to be cleaned of dust every day.
2. Pressure of compressed air must be inside the reasonable arrangement in order to prevent dam-
aging to small components of inner machine parts.
3. Check inter circuit of welding machine regularly and make sure the cable circuit is connected cor-
rectly and connectors are connected tightly (specially insert connector and components). If scale
and loose are found, please give a good polish to them and then connect them tightly again.
4. Avoid water and steam to enter into the machine. If they enter the machine, please dry the ma-
chine and then check insulation of machine again (including between connectors and mantle, be-
tween connectors and connectors).
5. If welding machine will not be operated for longer times, it must be put into packing box and
stored in dry environment.
