Description
BÖHLER EAS 4 PW-FD is a rutile flux cored welding wire with fast freezing slag providing excellent positional
operating characteristics and fast travel speeds. It is easy to use and operates with a powerful penetrating
spray arc transfer, minimum spatter formation and self releasing slag.
This flux cored welding wire offers many economical and quality advantages over solid wire pulse arc welding.
High deposition rates and productivity gains are easily achievable. Additional cost effective benefits are offered
through use of less expensive shielding gases (Argon +15-25 % CO2 or 100 % CO2), good wetting characteristics
(less grinding), little temper discoloration & bead oxidation (less pickling expenses), easy operation and safe
penetration (reduces the risk of weld defects and associated repair work costs), and smooth and clean weld finish
(less post weld work). Due to its characteristics mainly for positional welding and service temperatures between
-120 °C to +400 °C. Resists intergranular corrosion up to +400 °C. For downhand & horizontal welding
positions (1G, 1F, 2F) our flux cored wire BÖHLER EAS 4 M-FD should be preferred.

Welding with standard GMAW-facilities possible, slightly trailing torch position (angel appr. 80 °), slight
weaving is recommended for positional welding; when using 100 % CO2 as shielding gas it is necessary
to increase the voltage by 2 V; the gas flow should be 15 - 18 l/min.
