I am new to the forum. This Econo Tig was used to join sheet metal and relatively thin flanges to tubing.

Today the machine only works at a low amperage appropriate to 24 to 26 gauge steel. Previously, pushing down the pedal was accompanied by a louder hum but no longer is true even when...

I have just joined a club here at school and we have an Econotig SN# KJ063776. Whenever we try to TIG weld with it it seems as if it is going full current.
We started with the peddle and A to B closes as it should when the peddle is initially pressed....

Im looking for two informations:

and
2-information for the Econotig arc starter electronic circuit diagram.
