Well, the way u become a great welder is to be a poor vacuum
caster!!! And I’m well on my way!!
But, found a great product for shielding small or large work…
RectoRshield (this is how it is written on the tube). It’s a
paste, large tube for Thermal Absorption … and it really works
great!!
Found at your local Plumbing supply. Can be used on gold,
silver, Copper(all I’ve tried) for brazing, WELDING, soldering,
and does not splatter, drip or separate… and is removed with
water and is oderless, non-staining(from the tube and true).
