Bruce,
You have (I think) one of the cheap autodark helmets, made famous by Harbor
Freight etal.
When I was doing my ME in the Uni lab in Christchurch, we had a Speedglass
helmet there. You had to remember to turn it on, but it was noticeably
clearer than my cheapie one I got from HF via a friend. It was also 5x the
price, but if I was welding all day, it would be the go.
Are you using the pulser? makes thin stuff easier,but can upset some cheap
helmets.
Geoff
