Is there anybody there with experience using Lincore 36LS self shielded fluxcore wire? When I put 1st hardfacing layer on E71T-1 underlayer, I’m getting “wormholes” porosity. But on second & third layer no problems at all. All time I used same parameters: voltage, stickout, etc. Cleanliness is not an issue. Any idea, what’s the problem?

Thanks
