Using the Lincoln Flextec 350XP is straightforward. First, connect the 8.5 ft input power cord to a suitable power source. Then, based on your welding needs, choose the right welding process from the available ones like MIG, Flux - Cored, etc. If you want to use the Pulsed MIG mode, make sure to pair it with a compatible Arclink - capable feeder. When setting up, take advantage of the streamlined operator panel to quickly get things ready. For safety, always work in a well - ventilated area and wear proper protective gear. To keep your Flextec 350XP in good shape, regularly check the components, especially in high - temperature environments. Clean it after use to prevent dust and debris from affecting its performance. If you encounter any issues, refer to the spec sheet or contact customer support.
