results
The SRM® current shows “0” or is set too low.
• Increase the SRM® current parameter in increments and check if the
results improve.
The welding energy is not set correctly.
• Adjust the welding energy.
The cable connections are too loose, resulting in contact resistances.
• Check that all cable connections and earth clamps are mechanically
secured.
The stud is too loose or not fully inserted into the stud chuck.
• Push in the stud up to the stop. Replace the stud chuck if necessary.
There is a magnetic blow effect. The arc is forced into a certain direction.
• Change the earth clamp fixture, place iron parts on the edges or rotate
the welding gun.
The height of lift and/or the immersion depth are not set correctly.
• Adjust the height of lift and/or the immersion depth according to the
operating instructions for your welding gun.
You have used low-quality studs with inaccurate dimensions or a poor
surface finish.
• Only use SOYER® welding studs.
The welding time and/or the gas flow are not set correctly.
• Readjust the welding time and/or the gas flow.
The basic material is not suitable for welding.
• Use suitable material combinations.
There is one-sided
beading at the same
positions.
The beading is caused by the magnetic blow effect. The arc is forced into a
certain direction.
• Change the earth clamp fixture, place iron parts on the edges or rotate
the welding gun.
The SRM® current shows “0” or is set too low.
• Increase the SRM® current parameter in increments and check if the
results improve.
Intensive sparking,
the stud flange has
almost melted away.
The main current duration is set too high.
• Readjust the time for the main current duration according to the table.
The welding current is set too high.
• Readjust the welding current.
