To Next PageTo Next PageWhat to do if CIGWELD Transmig 165ST Welding System produces porosity due to dirty metal?
To address porosity issues when welding with your CIGWELD Welding System, make sure to thoroughly clean any contaminants such as dirt, oil, paint, oxidation, or grease from the workpiece before welding.
Why does my CIGWELD Transmig 165ST have porosity problems related to shielding gas?
If you're experiencing porosity issues with your CIGWELD Welding System, ensure that the shielding gas cylinder is not empty and that the flow meter is correctly adjusted to 15 liters per minute.
How to prevent porosity when welding in windy conditions with a CIGWELD Transmig 165ST Welding System?
If you're getting porosity while using your CIGWELD Welding System, shield the weld area from the wind or increase the gas flow.
How to troubleshoot gas leaks causing porosity in my CIGWELD Transmig 165ST?
To fix porosity issues in your CIGWELD Welding System, check for gas leaks between the regulator/cylinder connection and in the gas hose to the Power Source.
