[TheForge] welding heat

Chuck -

I use a #3 with no problems.
And a #3 blocks the IR. The type I have also block all UV.

All the best,

Bob

Hey Bob,
My  Didymium/gold face shield  is equivalent to a 3.5 shade welding filter.
I need at least a #5 standard welding  filter to be able to forge weld for
long periods of time.
 When I turn away from the fire with my hands holding the billet. I can see
in my shop with the Didymium/gold face shield, but with a welding shade I'm
essentially blind until I can put down the billet and lift the shield

The #5 doesn't reduce sodium flare or block the heat waves from the IR so I
can't see the billet as well as with the Didymium/gold face shield.

Other than these differences, the shields are equivalent.

I suggest you try a Didymium/gold face shield  and see for yourself.
Chuck
