Common Lincoln square wave 200 problems with quick solutions
With offering outstanding performance, the Lincoln Square Wave 200 welders may show some problems. Understanding those issues can help the welder solve them, avoid disturbance, and make the welding more precise.
So the problems you may face while operating a square wave of 200 welders are:
The operator cannot establish a welding arc
The welder may notice a spark at a high frequency in the electrode during operating this welder. It is made from tungsten. It can prevent the welder from establishing any welding arc.
You may face this problem if you run your welder at its regular rated open-circuit voltage. If the machine drives the welding current over a gap between the base metal and the electrode tip, it can maintain the welding arc.
Thus, a welder needs to strike and generate the proper arc readily. Otherwise, the welder won’t be able to weld on the work surface.
Solutions
There’s can be any source of this problem. The main reason could be the low current control. If so, increasing the current can help avoid the disturbance. You can also lower the proportion of helium that is used as a shielding gas in a helium mix.
Another effective solution is to repair the electrode. The electrode may become excessively large or get polluted, thus creating the problem. in this case, replacing or sharpening the electrode can fix the issue.
No output or fan
Your Lincoln Square Wave 200 may seem completely dead if there is no output or fan. So you may be planning to throw your welder in the garbage. Before doing so, ask for help from a professional mechanic. Fixing the issue can save you the whole amount needed to buy a new Lincoln Square Wave 200.
Solutions
Verify the input voltage of the welder. The input voltage must be compatible with the rating plate and connection. The welder machine comes with information about all the required ratings.
You can also get the right information by checking the welder’s user manual. Inspect to make sure whether the input power switch is in position and you connect the welder to the power outlet.
Another potential reason for the dead-looking welder is missing or blown fuses in the input line. So check for this problem and if it happens, insert the new fuses in your Lincoln SW 200 welder to restore its life.

Overheating issue
Many welders experience that square wave 200 becomes overheated more often and encourages the thermostat to turn on. Despite this, the yellow light placed on the front panel flashes. Some welders also complain that their fans run but don’t cool down the heat.
Solutions
The most common reason behind this problem is that the dirt and dust may get a block. So, blowing out the dirt and dust using a blower will clean the device and restore its performance.
Another reason is that the exhaust louvers and brickwork may be obstructed due to inadequate clearance around the welder.
Sometimes the exceedingly acceptable duty cycle also leads the welder to become overheated. In this case, reduce the duty cycle and your welder will run precisely without getting heat.
No flow of gas
Another common Lincoln Square Wave 200 is that sometimes it doesn’t flow gas after turning the petrol on in tig mode. Though there is no noticeable gas flow, the welder still gets output and a fan.
Wondering how to comprehend this? Paying attention, you should hear a click sound. It indicates that the gas solenoid valve is running.
Solutions
Double-check the setting if the gas supply is turned on. A flow regulator set too low can also cause this problem. Other things that can be responsible are pinched gas hoses or obstructed gas flow.
To solve this issue, clean the gas hose using a blower. You can also call the gas distributor to clear the blocked gas hose and refill the gas storage.
Most Common FAQs
A Lincoln Square Wave 200 is suitable for welding stainless steel, steel, aluminum, and other metals. You can also weld chromium-molybdenum steel alloys using a Lincoln SW 200 welder.
Lincoln SW 200 welder has the dual capability of running on 110 and 220 volts. So you can connect this welder to your regular 110V power outlet and weld.
Final words
Lincoln Square Wave 200 is a high-end tig welder and is popular among pro welders. But, you may still face some difficulties while using this welder machine. The Lincoln Square Wave 200 problems we have discussed above are the most experienced.
As a result, it is worthwhile to become aware of them and comprehend the process of resolving them. This will not only help you avoid interruption during welding but also maintain the welder for the greatest performance.
