Why is my Kemppi 350 producing dirty, poor quality welds?
- T
  Tyler MorganAug 1, 2025
  A dirty, poor quality weld from your Kemppi Welding System can arise from several factors. You should: * Check the shielding gas supply. * Check and set the correct gas flow rate. * Ensure you're using the correct gas type for the application. * Verify the gun/electrode polarity. For example, when using Fe solid filler wire, the earth return should connect to the – pole, and the wire feed unit to the + pole connector. * Confirm the correct welding curve is selected. * Check the correct Channel (job) number is selected on the PF65 function panel. * Ensure the power supply isn't experiencing a phase down.

Why does my Kemppi Welding System have variable welding performance?
- R
  Rachel SmithAug 8, 2025
  Inconsistent welding performance with your Kemppi Welding System can be caused by: * Incorrectly adjusted wire feed mechanism. * Incorrect drive rolls being fitted. * Wire spool overrun tension not correctly adjusted. * A blocked gun liner (replace if necessary). * The wrong gun liner fitted for the filler wire size and type. * Contact tip issues (size, type, and wear). * Gun overheating during application. * Loose cable connections and earth return clamp. * Incorrect welding parameter settings.
