Why is the electric arc irregular or unstable on my WIELANDER+SCHILL InvertaPuls IP4-3 Welding System?

If the electric arc from your WIELANDER+SCHILL Welding System is irregular or unstable, several factors could be responsible. Ensure that the welding voltage is correctly set. Adjust the wire feed regulator to correct the amount of wire. Make sure there is good contact between the workpiece and the clamp by removing any rust or paint. Change the contact nozzle if it's worn or has the wrong diameter. Adjust the gas flow to the correct setting. Clean the workpiece in the welding area to remove any paint, rust, or grease. Clean or replace a dirty plug-in spiral. If these steps don't resolve the issue, the device may have a performance grade malfunction and should be taken to a service center.
