摘要：
A plasma arc welding torch wherein a first plasma gas is directed through the body of the welding torch and out of the body across the tip of a welding electrode disposed at the forward end of the body. A second plasma gas is disposed for flow through a longitudinal bore in the electrode. The second plasm gas enters one end of the electrode and exits the electrode at the tip thereof for coacting with the electric welding arc to produce the desired weld. A shield gas is directed through the torch body for circulating around the head of the torch adjacent the electrode tip.
