Hi All,
A year ago I bought a DC TIG welder from Rtech, I did not buy the AC/DC version as My skills are not up to welding alloy, I have a friend who has the "Bee's knees" Rtech plant that I get to do any alloy repairs.
Previously I had a scratch start inverter but only got mediocre results with it, the arc never seemed stable. I had difficulty with distorted vision wearing glasses inside several different auto darkening welding helmets I tried, adding lenses to normal masks did not help much either

When I ordered the Rtech I opted to buy their "True Colour" mask at the same time, (saving shipping)
The new mask has made a huge difference to my welding, the larger viewing area and clarity are 1st class
I can now see where I'm aiming the torch LOL,
I asked three friends who are very experienced welders to try out the mask and they all said "I'll have to get one of these"
