Still deciding about getting a solar helmet. Borrowed this one off a friend to try. Its a Jade products ADSH G---they are advertised regularly in Model Engineer magazine at around £50. It seemed fine but I'd like comments on one aspect. When I started the arc I saw a slight sort of flare for a very brief instant---not a real arc effect--more like a bit of the effect you get with those hand held sparklers you see on bonfire night ( the ones that look like welding rods!). Once the weld started it was fine with the arc visible but looking quite dull. The mask info says it darkens in 1/10,000 second. Is this the sort of performance you should expect with this sort of helmet?
