FERROCRAFT 16 TWINCOAT
Ferrocraft 16 Twincoat is a hydrogen controlled welding electrode from CIGWELD
offering exceptional AC/DC welding performance in all welding positions, including
vertical-up and overhead. The unique dual or twin flux coating enables easy arc
starting, ultra smooth performance and reliable weld deposit toughness to be
achieved in all welding positions. Ferrocraft 16 Twincoat produces excellent AC
performance, particularly on portable 240V AC welding machines. It offers excellent
low current performance which is important for achieving the best bead shape whilst
producing no undercut in the difficult vertical-up and overhead positions. Ferrocraft
16 Twincoat is an easy-to-use E4816/E7016 type electrode for the all positional fillet
and butt welding of heavier mild steel sections or joints under high restraint. It is also
suitable for a wide range of welding applications on selected Carbon-Manganese,
low alloy and cast steels. The easy operation, reliable Grade 3 weld metal properties
and low hydrogen status make the electrode ideal for maintenance welding jobs,
including the repair of earth moving equipment and the ‘buttering’ of steel sections
prior to the application of hard surfacing.
Features:
Unique dual or twin coated flux for easy arc starting.
Excellent operator appeal / Hydrogen controlled.
Ultra smooth pereformance in all welding postions.
Reliable Grade 3 weld metal properties.

FERROCRAFT 7016
ALL POSITIONAL
EXCEPT VERTICAL DOWN
CONSUMABLES
Ferrocraft 7016 is a basic, hydrogen controlled electrode that deposits weld metal
in the 550MPa class. It gives excellent operator appeal in all welding positions,
except vertical-down and exhibits a smooth, penetrating arc with excellent bead
appearance and shape. The full covering slag is easy to control and remove.
Ferrocraft 7016 is a versatile hydrogen controlled electrode, giving excellent all
round arc performance and reliable impact toughness to -30°C. Ferrocraft 7016
is designed for all positional (except vertical-down) fillet and butt welding jobs
where “hydrogen control” is required and the emphasis is on operator appeal. It
is also recommended for more critical applications where low temperature impact
toughness to -30°C is required. Typical applications include pressure vessel
fabrication, bridge and ship building and equipment repair and maintenance work.
Features:
Fully Basic Hydrogen Controlled E4816 / E7016 Type Electrode.
Excellent Operator Appeal in All Positions.
Ideal for Fill and capping passes.
Excellent Impact Toughness to -30°C.
Applications include pressure vessel fabrication, bridge, ship building, equipment
repair and maintenance work.
