Adapter Helps To Aline Plasma Torch

Abstract

Simple adapter allows plasma welding torch alined accurately on weld seam. Adapter fits over nozzle of torch. Light from pilot arc inside torch passes through central orifice in cone. Light emerges from cone as beam that creates spot of light at point where torch impinges on workpiece. When torch is alined with work, adapter is removed, plasma arc struck, and welding proceeds.
