FAQs
Which generator do I need for my stud welding machine?
The required generator output depends on your welding current. Our diagram shows you the minimum power – choose a generator above the purple marking to ensure consistent welding quality.
What cable length is allowed for drawn arc stud welding?
Use our diagram: find your welding current and cable cross-section – this will show you the maximum permitted length for optimal welding results in drawn arc stud welding.
How do I carry out a test weld?
A test weld must be carried out before the start of each welding run and after any change to the parameters. Procedure: (1) Set the welding parameters according to the reference table, (2) weld a stud onto a test piece of the same material and thickness, (3) visually inspect for a complete weld seam and an even bead, (4) Bending test: bend the stud to 60° – no crack in the weld zone means the test has been passed. Series production may only commence once the test weld has been passed.
How do I set the right welding parameters?
Weld connections depend on the correct setting of five parameters. Our expert explains in the video how welding current, process duration, stud projection, lift height, and damping interact – and how to adjust them to suit your material and working conditions.
