• General fabrication
7018AC 5/32 4.0 130 – 200 140 PRS7018AC-532X5
The ProStar 7018AC electrode is
Typical Mechanical Properties* As Welded
specifically designed to produce
Yield Strength, psi (MPa) 67 (462)
optimum arc characteristics when
Tensile Strength, psi (MPa) 81 (559)
used with AC power sources having
Elongation in 2" (51 mm) 26%
75 – 80 open circuit voltage. When
compared to the standard ProStar
7018 electrode operating on AC, the
7018AC provides easier arc starting
and restrike, a smoother arc, and
lower spatter. It's also easier to operate
than most low hydrogen electrodes
and usable on a wide range of steels.

The ProStar 7018 electrode is a
Typical Mechanical Properties* As Welded
moisture-resistant, all-position, low
Yield Strength, psi (MPa) 67 (462)
hydrogen, iron powder electrode
Tensile Strength, psi (MPa) 81 (559)
known for its superior welding
Elongation in 2" (51 mm) 26%
performance, tough mechanical
properties, crack resistance, high
operator appeal, and consistent
quality. The smooth metal transfer
keeps spatter to a minimum, and
the complete slag coverage is
designed for easy removal. This
premium-quality electrode meets
a multitude of codes and welding
specifications. * The data contained herein is based on testing performed under standard laboratory conditions. In normal practice,
the results obtained may vary depending upon welding parameters, weld metal cooling rate, and the base plate
being joined. The user should always test the electrode prior to its application.
