Ensures precise parameters and accuracy. Integrated digital timers come complete with presettable preflow/ postflow, burnback, spot and delay (stitch) timers. Independent timers for MIG and spool gun. Line voltage compensation keeps power constant even if power input varies by ±10 percent. EZ-Access™ consumable compartment and parameter chart. Set weld parameters right the first time with convenient flip-down compartment that provides fast access to parameter chart and consumables. See page 3 for more information. Active Arc Stabilizer ™ minimizes weld cleanup, and provides excellent starts proven superior to the competition. Auto-Gun Detect™ allows operator to simply pull trigger on MIG gun, spool gun or push/pull gun. Automatically detects and recalls the voltage, wire feed speed and timer of the active gun. See page 3 for more information. Heavy-duty aluminum two-drive-roll system. Fan-On-Demand™ cooling system only operates when needed, reducing noise, energy use and the amount of contaminants pulled though the machine. Superior aluminum MIG welding with direct connection of optional spool guns and push-pull guns. Directly connect your Spoolmate™ 200 and Spoolmatic® spool guns or XR™ push-pull guns. No extra module to buy or install. Welder is warrantied for three years, parts and labor. Original main power rectifier parts are warrantied for five years. Gun warrantied for 90 days, parts only.
