Unibraze 7018AC
(E7018 H4)
DESCRIPTION:
Highly recommended for applications using small 208/230V, single phase AC welders, UNIBRAZE 7018AC has
good operator appeal, excellent re-striking characteristics and an extremely stable arc. UNIBRAZE 7018AC is
also an excellent choice for skip or tack welds. The slag is self-removing in most applications. UNIBRAZE
7018AC will work well on all AC power sources and performs exceptionally well on utility-type welders.
APPLICATIONS:
• low-, medium- and high-carbon steels
• skip or tack welds
• shops, farms, hobbyist
• some high-strength low alloy steels
