Powerful Performance From the Ground Up. Out in the shipyards, construction sites and fabrication shops, it pays to keep it simple. The Flextec 500X multi-process welder is easy to set up and operate, yet rugged enough to stand up to heavy-duty indoor and outdoor applications. Basic pulse MIG capability is standard on the Flextec 500X , including weld modes for carbon steel, stainless steel, aluminum and metalcore electrodes. The Flextec 500X welder is also equipped with CrossLinc® technology giving you the flexibility to control the machine from hundreds of feet away without a control cable. Ready-Pak ships fully assembled and comes with the Flex Feed 84 wire feeder that features consistent feeding over long conduit runs, 4 user memories, and advanced MaxTrac® wire drive design. This bundle also includes the Magnum PRO Curve 400 welding gun, inverter and feeder cart, flowmeter regulator and hose, and the necessary cables and connectors.
