Using the Flextec 350X is straightforward. First, connect the 8.5 ft input power cord to a suitable power supply. You can choose from various welding processes like MIG, Flux - Cored, DC TIG, Stick, and Air - Carbon Arc Gouging. If you want to control the welding output remotely, use the CrossLinc technology with the standard weld cables and a CrossLinc accessory. For wire welding, pair it with an LN - 25X. When using it, make sure to operate in a well - ventilated area. Avoid exposing it to extreme temperatures and moisture. Regularly check the components for any signs of wear and tear. Clean the power source gently with a dry cloth. If there are any issues, refer to the spec sheet or contact the manufacturer.
