image.jpg image.jpg image.jpg image.jpg image.jpg I have a old transformer stick Tig welder .The stick welding is working fine. The Tig is giving a arc but the is very little High Frequency at the tungeston. I have removed the HF transformer and have done a resistance test on both windings. Ohm , ring test , mega test
All the readings are in the photo.
The indication to me is the installation is breaking down.
I will post extra photoes on the next post
I have written on the transformer primary and secondaryimage.jpg

Dow the bottom of the welder the is 4 heat sinkers with electrodes When selecting the HF switch there is a arch between them what is the reason for the electrodes And how important is the gap.

Do you think that every thing points to the transformer.
I do not have a circuit digram for this welder .
Is there anyone that can help me out with a circuit digram
I do not know how the transformer is wound to obtain a HF .
Can this be explained.
Thank you.
