Adjusting the depth of immersion

Switch off stud welder to adjust the depth of immersion.

The depth of immersion is the distance the stud projects over the end of the ceramic
ferrule, the gas shroud or the support tube. When placing the welding gun on the
workpiece, the stud is pushed back this distance. During welding, the stud will
immerse up to this length into the liquid weld pool on the workpiece. The process of
adjusting the depth of immersion is the same for both welding with shielding gas and
ceramic ferrules. The depth of immersion always depends on the stud diameter.
The following illustrations show the depth of immersion when welding with ceramic
ferrule and shielding gas.
