Postalloy PS98WC1.2mm (11.4 Kg) Air Filters Height Universal Ready Rest Suits Diameter:12mm 5 16" Height Universal Ready Rest Suits Mig & Tig Universal Rests MIG TIG Eectrode holder Supplied as Standard 4 Drawer Module x2 Postalloy PS98 is a metal cored triple deoxidized Iron based wire alloyed with Chromium and Tungsten Carbide This product is primarily used as a matrix alloy for the Tungsten Carbide embedding process Unlike soft mild steel welding wires which are commonly used in the embedding process the microstructure of Postalloy PS98 is designed to encapsulate and protect the Tungsten Carbide particles from premature erosion Many of the common embedding wires are solid which require high voltage and amperage settings to achieve a fluid puddle Postalloy PS98 is metal cored and develops a spray transfer at very low current levels This combined with its unique alloy content forms a very fluid weld puddle This promotes an even dispersion of Tungsten Carbide particles within the weld puddle These unique properties make it an ideal choice when used with the Tungsten Carbide embedding process
