Using the Miller XMT 350 CC/CV Multiprocess Welder is quite straightforward. First, connect it to a power source within the 208 - 575V range. Thanks to the Auto - Line™ technology, you don't have to worry about manual linking. For starting the welding process, use the Adaptive Hot Start™ for stick electrodes. In Stick and Wire modes, take advantage of the infinite arc control to adjust according to the material and position. When using the Lift - Arc™, be careful to minimize electrode contamination. Connect your spool guns, feeders, or remote controls to the 14 - pin receptacle. Select the appropriate process on the control panel, which is designed to be user - friendly. You can use the large digital meters to set the weld output easily. For cable connections, pick either the Dinse - or Tweco® - style connectors. When it comes to maintenance, the Wind Tunnel Technology™ helps protect the internal parts. The Fan - On - Demand™ cooling system only works when needed, but still, make sure to keep the area around the machine clean to avoid contaminants. Also, check the control panel's polycarbonate - blended cover regularly for any signs of damage.
