Thanks Amanjot,very helpful.

Spent over forty years plodding away with the old type helmet with different lenses,never used an auto helmet.I give them a once-over every so often on ebay etc,but the range boggles me.

The one I`ll avoid states "arc flashes", in the cons....sounds nasty!

I`ll look at your tig welder blog later.I`m a qualified welder,but believe it or not have only used oxy-acetylene,oxy-propane,stick and mig forms!

Always plenty to learn,especially with being out of the trade for years and only tinkering in my spare time with various projects.Occasionally consider new kit,since oxy-acetylene bottles became more difficult to source.BOC eh!

What has replaced oxy-acetylene for some purposes.I use a 1mm slitting disc in my grinder for cutting most metalwork now,but what of other requirements?

I have an outdoor circular sawbench I`ll need to get the "hot spanner" on soon to free some components off....what`s the cheapest solution nowadays for applying heat for the hobbyist,I wonder?

What are the pros of these helmets?
