UNIMIG Viper Multi 165 Problems and Solutions

some common issues and problems with the UNIMIG Viper Multi 165 welder, along with step-by-step solutions from experts:

Issue: The welder won't turn on. Solution: Check the power cord to make sure it's properly plugged in. If the power cord is plugged in and the welder still won't turn on, check the fuse. If the fuse is blown, replace it.

Issue: The welder is arcing but not welding. Solution: Check the settings on the welder to make sure they are correct for the type of welding you are doing. If the settings are correct, check the gas flow to make sure it is adequate. If the gas flow is adequate, check the contact tip to make sure it is clean and properly installed.

Issue: The welds are porous. Solution: This is usually caused by inadequate shielding gas coverage. Make sure the shielding gas is flowing properly and that the contact tip is clean and properly installed. You may also need to adjust the welding parameters.

Issue: The welder is overheating. Solution: This is usually caused by welding for too long at a high amperage setting. Allow the welder to cool down before welding again. You may also need to adjust the welding parameters.

Issue: The welder is making a loud noise. Solution: This is usually caused by a loose or damaged wire feed. Check the wire feed to make sure it is properly connected and that there are no kinks or breaks in the wire.

If you are still having problems with your UNIMIG Viper Multi 165 welder, you can contact UNIMIG customer support for assistance.

Here are some additional tips for troubleshooting common MIG welding defects:

  • Porosity: This is the most common MIG welding defect. It is caused by gas becoming trapped in the weld metal. To prevent porosity, make sure the shielding gas is flowing properly and that the contact tip is clean and properly installed. You may also need to adjust the welding parameters.
  • Incomplete fusion: This is caused by the weld metal not melting the base metal completely. To prevent incomplete fusion, make sure the welding parameters are correct and that the welding speed is not too fast.
  • Cold lap: This is caused by the weld metal not fusing to the base metal. To prevent cold lap, make sure the welding parameters are correct and that the welding speed is not too fast.
  • Spatter: This is caused by molten metal splashing out of the weld pool. To prevent spatter, use a sharp contact tip and keep the shielding gas flowing properly. You may also need to adjust the welding parameters.

I hope this helps!
