T-PUT Thermanit 308 H-PW description: Thermanit 308 H-PW is a strip alloyed flux cored wire with rutile slag characteristic for position welding of high temperature austenitic CrNi steels. The sustain effect of the fast freezing slag enables out of position welding with high current and high welding speed with mixed gas M21 and 100% CO2 according to EN ISO 14175. Fine droplet, almost spatter free welding, very intensive spray arc, secure penetration, self detaching slag, as well as good wetting bead appearance lead to high welding quality and simultaneously short welding times.
