[TheForge] autodarkening SHIELD! really

[John Allen]

I have the Bernard Q300 gun and it has a nice feel to it. Unless you
are welding 300 amps non stop then you don't need water cooled. Water
cooled is mainly for shops that have a dedicated welder and machine
for hot work.

I bought the digital elite auto helmet and I love it. I waited to get
this one because you only have 1 set of eyes and the 4 sensors help me
keep my eyes longer. Plus it has the fastest guaranteed reaction time.
Before I bought the auto, I would leave my 2.5 x 4 helmet with flip
lens almost closed, leave about a 1/4 inch gap. That way I could weld
and quickly see to the next spot.
