Adjusting the depth of immersion
DANGER
Switch off stud welder to adjust depth of immersion.
The stud must come into contact with the adjusting screw of the standard
stud holder.
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.
How to adjust the depth of immersion:
• Insert the relevant stud (6) into stud holder (4) until stop
• Loosen both Allen screws (1)
• Move support legs (2) until the required depth of immersion is obtained
• Tighten Allen screws (1)
