Ive been doing some reasonable looking (although not without fault) runs on 1.5mm aluminium (with no backing) with 1.6 Lanthanated, about 25% Ep balance and 65A, ive tried varying frequencies, but im really struggling to tack 2 pieces together, my arc always seems to favour one side of the join and then blow holes. The 2 pieces fit pretty well together, so little to no gap between the 2.
Ive upped it to between 70 and 90A for tacking, but the result is still the same, i cant focus the arc directly in the centre to melt both sides at once.
Any ideas? Thanks
