A seamless, copper free, cored wire designed to weld thick steel components. The diffusible hydrogen level is consistently below 4mL/100g of deposited weld metal and with the seam of the wire being laser welded this ensures no moisture pick up. The wire is not copper coated, which means there is no chance of copper flakes contaminating feed liners, torches and contact tips. Dual Shield Prime 71 LT H4 is designed to weld medium strength steels and provides excellent impact toughness down to -40 C Dual Shield Prime 71 LT H4 is designed to be used with either CO2 or Ar/CO2 shielding gas mixture.OrderingPart No.Description35MT12691VDS Prime 71 LT H4 1.2mm 15kg - 126 Cartons35MT12560VDS Prime 71 LT H4 1.2mm 4x5kg35MT16246VDS Prime 71 LT H4 1.6mm 15kg DISCONTINUED35MT16690VDS Prime 71 LT H4 1.6mm 15kg DISCONTINUEDPlease note These products are made to order so returns/cancellations cannot be accepted.SpecificationsTypical Charpy V-Notch PropertiesImpact ValueTesting TemperatureAs Welded 100%
