If you are tired of regular large-sized welders, you need a TIG welder. Now when it comes to TIG welder, there are many models available. But, the Lincoln Square Wave 200 Welder stands out. It is portable and has an outstanding performance compared to the small and compact size.
However, when using Lincoln Square Wave 200 Welder, you can face some problems. If you know about the issues, your life will be much easier while you troubleshoot.
Hence, today we are here to discuss Lincoln Square Wave 200 Welder problems and everything else that you need to know to troubleshoot it.

Common problems when using Lincoln Square Wave 200 Welder (with quick fixes)
Below, we will list a few of the common problems you can face with the Lincoln Square Wave 200 Welder.
The operator cannot establish a welding arc
Sometimes you will see the presence of spark at high frequency in the electrode, which is made of tungsten. But, still, the operator cannot establish any welding arc. Additionally, this problem usually occurs at regular rated open-circuit voltage.
A welding arc is maintained when the welding current is driven over a gap between the electrode tip and the base metal. A welder must be able to readily and rapidly strike and generate the proper arc. If this doesn’t happen, you won’t be able to weld any metal.
Quick fix to try: there are many reasons that can cause this problem. The first reason is the most simple, your current control may be too low. You only need to increase the current.
Reduce the proportion of Helium in a Helium mix used as a shielding gas. Last but not the least, the electrode must be repaired; it may be polluted or excessively large.
Replace or sharpen the electrode if necessary. Furthermore, when starting, the Tungsten may be too far away from the workpiece.
No output or fan
In simple terms, the Lincoln Square Wave 200 looks utterly dead in this situation; there is neither any fan nor any output.
You might think that your Square Wave 200 is not useable anymore and is gone forever. But before you call any professional repairman or throw away the machine. Try these quick fixes.
Quick fix to try: Make careful to verify the machine’s input voltage. The input voltage must match the voltage connection and rating plate. All the needed ratings are listed on the device. Moreover, you may also consult the manual for further information.
Check to see whether the input power switch is in the “on” position and that the machine is connected to the power outlet.
The fuses in the input line can be blown or missing. Replace the blown or missing fuses in your Lincoln Square Wave 200 to bring it back to life.
The Square Wave 200 can overheat regularly, and when this happens, the thermostat is turned on. Along with it, the yellow light on the front panel also glows or flashes. You’ll also note that the welder’s fan runs but produces no heat.
Quick fix to try: The cooling ducts within the welder may have been blocked by dirt and dust. Get a blower and blow out the device with clean, dry low-pressure air to remove all dirt particles.
Due to insufficient clearance around the machine, the air intake, brickwork, and exhaust louvers may be obstructed. Welding applications may also surpass the acceptable duty cycle. Reduce the duty cycle, and that’s all there is to it.
No flow of gas
When amptrol is turned on in TIG mode, you will see that there is no gas flow. The machine will have an output as well as a fan. However, there will be no gas flow.
You might wonder how you can comprehend this. You will hear a “click” sound, which indicates that the gas solenoid valve is working.
Quick fix to try: always double-check if your gas supply is depleted or not switched on. This issue can also be caused by a flow regulator that is set too low. Furthermore, the gas hose might be pinched, or the gas flow could be obstructed by dirt.
You can clean your gas hose with a blower or with rags. However, for better results, you should contact your gas distributor as the distributor can clear your blocked gas hose as well as refill the gas storage.
What are the parts of the Lincoln Square Wave 200 Welder?
So far, we have looked into the Lincoln Square Wave 200 problems. Now we will look into a few of the alternative parts for this welder. So, in case of a problem with the parts, you can replace them quickly.
TIG welding torch
The Square Wave 200 comes with a built-in gas solenoid. As a result, a TIG torch with a one-piece power or gas cable, as well as a pre-installed torch adaptor, is delivered as a ready-to-weld kit.
Connect the torch cable to the machine’s (-) terminal and the work clamp to the (+) terminal. You have an option to add from five kits torches additionally. They are as follows.
- Kp508 – for pta-17 series torches.
- Kp509 – for pta-26 series torches.
- Kp507 – for pta-9 series torches.
As with most welders, this also comes with thermostats. Thermostats keep the machine from overheating during operation. A lack of cooling air or using the equipment beyond its duty cycle and output rating might result in excessive temperatures.
If the operating temperature becomes too high, the thermostats will cut off the output voltage or current.
This welder comes with a Tungsten electrode which is very handy to use and makes your welding work easier.
