Electrode extension

 

       Easiest to measure is the contact tip distance from the joint surface, A

rule of thumb says that a normal distance is 10-15 x diameter of the electrode. Too small

stick-out increases the risk of burn-back, where the arc will weld the electrode together

with the contact tip. Too long a distance to the workpiece will increase the risk for stub-

bing, especially at the start.

The contact tip-to-work distance also has an influence on the current and penetration

profile. If the electrode extension is increased the current and heat input decreases while

the amount of deposited metal remains. This reduces the penetration, and if it was unin-

tentional a risk for lack of fusion appears. A good rule is therefore to keep the wire

out constant during the welding operation.
