Weller WES51... | Answered on Jun 28, 2019

Depending on the make and model, it may differ a bit from my inverter welder, but looking at mine:
Positive "Torch" cable-socket is red, and
Earth "Workpiece" cable-socket is black.
Otherwise, the way I tested mine (to find out voltage output):
Use a multimeter (analogue or DMM) set to the highest DC voltage scale, or auto-ranging scale.
Turn welder to minimum power setting (lightest rod setting).
While welder is switched on, gradually reduce the meter's DC range until you get a reading (mine read 48V).
The red test-probe to positive socket gives a positive value
[nn.nn V], or deflects meter pointer right, while reversed polarity gives a negative value [-nn.nn V], or deflects meter pointer left.
As the voltage waveform is actually pulsating DC, the AC scale will also give a reading, obviously without polarity indication.

Go to your local welding supply store. A TIG welder is a specialized welder that cannot be found at a building supply store. Stores like Maine Oxy-Acetylene Supply or Grainger Industrial Supply will carry them. Look in the classifieds of publications like Uncle Henry's. There you might find a TIG welder that someone is selling—and it may be at a good price. Be sure to ask the owner questions and take a look at the TIG welder before buying it. Explore eBay. Yes, even eBay has TIG welders. You'll need to ask the buyer questions about the welder's history and more. Perhaps, if the seller is near enough, you might be able to pick up the TIG welder yourself and save on shipping. Visit online retailers. Retailers like Welders Direct or Welding Mart carry TIG welders and would be able to answer any questions you might have (see Resources below). Consider the manufacturer of the TIG welders themselves. Lincoln, Miller, Hobart and others have their own websites. Call the companies directly and ask a lot of questions. These vendors are the best product source for welders (see Resources below).

Sounds like main transformer is bad or bad connection. Unplug it and take it apart and check for loose connections. Good luck.
