            Can you weld galvanized fence posts
            ByDec 16, 2025
            1 Answer | 
            Answer This Question

            Weld‑Pak® 140 is not ideal. Galvanized steel is coated with zinc, which produces hazardous fumes when welded and can make it harder to achieve clean, consistent welds. While it can be done in some cases, the zinc coating must be removed in the weld area, and the work should only be performed in a well‑ventilated area with proper respiratory protection.

                  Not recommended this device.
                  We are disappointed with this device, we bought a welding machine and returned it 3 hours after purchase, when working it just gives you extra work and costs but the result is useless. does not match the price and quality.

                      Easy to setup, good quality item. I've done two of the small welding jobs I had in mind for this tool and while my welds aren't pretty they are doing the job. If you're going to use it with flux wire and no gas I recommend getting some nozzle gel to save the tip from splatter.
