Difference however is that Carbon and Stainless are continuous feed, duplex and higher nickel content type stainless wires move closer to dipping, and with inconel/hastelloy, I basically just hold the puddle in one spot, feed into the puddle for as much buildup as I need, then I just hold the filler metal in place until the puddle pulls away from the filler metal/detaches, and drops down to solidify.Carbon and Stainless - typically keep the tungsten pointing at the puddle, and the heat of the puddle is drawing down/pulling down filler metal which should be located on the leading edge of the puddle.With Hastelloy/INconel, the tig torch is typically pointing towards the leading edge of the puddle and adding filler metal towards the middle of the puddle and in between the leading edge/base of the puddle.Last edited by Thorton; 12-25-2012 at 04:10 PM.46’ sae30047’ sa200 w/Wisconsin VF451’ shorthood56’ shorthood56’ shorthood68’ redface69 redface07’ ranger 305G13’ sae300Inconel/Hastelloy – SS – Duplex – Chrome/Carbon Tig – F3Downhand – STT/RMD – F3F4 – B Pressure
