Controls/ Connections:
1) Amperage knob: The amperage knob controls the output amperage of the welding
machine. If the foot pedal is connected, the amperage is controlled with the foot
pedal, and not the Amperage knob.
2) Cleaning Effect Adjustment: The Clearance effect adjustment is used to control heat
between the workpiece and the tungsten. Turning it positive will allow for better
cleaning but less penetration, while dialing in a more negative setting allows for more
penetration but less cleaning. When at the “O” position, the ratio is 50% to 50%; at
“5” position, ratio is 80%, and at “-5” position, ratio is 20%
3) Digital Amperage Display: Using digital meters helps the user set amperage quickly
while STICK welding or TIG welding.
4) STICK/TIG switch: Rocker switch to control which process is used for welding.
5) Post-Flow Adjustment: Controls the seconds in which the shielding gas is allowed
to continue to flow through the torch after the foot pedal is trigger is depressed.
6) Pre-Flow Control: Controls the amount of time (measured in tenths of a second) that
the shielding gas is allowed to flow though the torch before the arc is ignited.
7) Power Switch: Located in the back of the machine. Powers the machine on or off.
8) Foot Pedal/ Panel Control Switch: Allows the user to select either option of
controlling the amperage, either through the control panel, or with the included foot
pedal.
9) AC/DC Switch: Easy switching between AC and DC welding. DC welding being
used for steel while the Ac setting is used for aluminum welding.
10)TIG Shielding Gas Connection: The shielding gas connection needs to be threaded
in tightly. (Avoid over-tightening)
11)Stick Welding Connection: Connect the included stinger for stick welding.
12)TIG Welding Panel Control: Connect the TIG torch connector in order to control
amperage via the panel controls.
13) Foot Pedal Connection: Connect the foot pedal connection in order to control
amperage with the included foot pedal.
14)Ground Clamp Control: Insert connector and twist clockwise to secure the ground
clamp.

15)Overheat Protection Light: If the welding machine exceeds the duty cycle in
operation, it may go into a protective state and stop working. Under these
circumstances do not power off the machine. This allows the internal cooling fan to
continue working to cool your machine. Once the machine cools down to safe
temperatures, you can continue to safely operate the machine.
16)** HF/Lift Start** : Some models may include a rocker switch which allows the
user to turn off the HF start and use Lift Arc to start the arc on the TIG torch

Troubleshooting
.
A、Black welding spot
——This shows the welding spot is oxidized without being protected effectively and you can
make the following inspection ：
1. Make sure that the valve of argon cylinder has been opened with sufficient pressure. As a rule,
if the pressure within the cylinder is lower than 0.5MPa, then it is necessary to refill the
cylinder.
2. Check if the argon flow-meter is turned on with sufficient flow. You can select different flow
rates in light of varying welding current, but too small flow may lead to inadequate gas
stiffness and thus failure to cover all the welded spots. We suggest argon flow should never be
lower than 3l/min no matter how weak the current will be.
3. The easiest way to check gas delivery is to touch the nozzle of welding torch to see whether
the gas passage of the welding torch is blocked.
4. Poor sealing of gas passage or lower gas purity will also give rise to welding quality trouble.
5. Strong air flow in the environment may also lead to deterioration of welding quality.
B、Difficulty in arc starting with easy arc breaking：
1. Make sure that the tungsten electrode in use is of good quality as discharge ability of inferior
tungsten electrode may fail the requirement；
2. Tungsten electrode without sharpening treatment is also unable to start arc and leads to
unstable arc.
C、Output current can’t reach the rated value：
Deviation of power voltage from the rated value will lead to unconformity of output current
value with the set value. When power voltage is lower than the rated value, maximum output
current of the welder may also be lower than the rated value.
D、Unstable current in the operation of the welder：
This may be attributed to the following factors：
1. Change in grid voltage；
2. Interference from the power grid or other power equipments.
E、： Severely burn of the tungsten needle
The duty cycle is adjusted too large, causing emission from the workpiece to the tungsten
electron for too long, resulting in severe heat of the tungsten needles.

160 SX/200SX AC/DC TIG STICK WELDER

F、The oxide film can’t be torn when welding aluminum:
1. The welding gear is selected wrong.
2. The duty cycle is adjusted too small;
3. The secondary inverter has field pipe damage.
G、The abnormal pilot lamp is on:
1、The light is on when the welder work abnormally, please turn off the power switch and then
reboot the machine, it can continue to use if it return to normal,
2、If the light is on repeatedly, please refer to the professional or the manufacturer for repair.
