   I had to search for that document as the link didn't work, probably the   
   ').pdf?' on the end it didn't like. The pedal looks just like the   
   Linemaster Varior used with my Hitachi TIG, I had to check that recently   
   and found the 50k pot was reading about 100k and not very smooth. Now   
   changed after locating a compatible direct replacement pot but still   
   something is not quite right with my TIG so it's going into the supplier   
   for testing. It took a while thinking about how to take the Varior pedal   
   apart as Linemaster indicates it can be mounted with the 2 screw holes   
   provided but no information about how to take the pedal apart to do so.   
   In the end I figured out it had to have a spring loaded pivot pin like a   
   large watch strap pin and that proved to be so, easy once you know how.
