Description
Rutile, strip alloyed, flux cored welding wire with fast freezing slag providing excellent positional welding
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.
BÖHLER SAS 4 PW-FD 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, good wetting characteristics (less
grinding), little temper discoloration and 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. For downhand and horizontal welding positions (PA, PB, PC) our
flux cored wire SAS 4-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
