Single-phase DC multiprocess power source that provides versatility and outstanding arc performance in CV mode (MIG) and CC mode (Stick and TIG).

• Weld MIG, TIG and Stick with one versatile machine. The price of a Shopmate 300 DX is roughly half the cost of buying individual MIG, TIG and Stick welding equipment.
• Single Process Selector Switch is "operator-friendly". Eliminates confusion caused by several switch combinations; making setup and operation easy.
• Lift-Arc TIG™ allows DC/TIG starting without the use of high-frequency. Starts the arc without contaminating the weld with tungsten.
• Large, dual digital meters enable the operator to preset weld voltage in CV mode and amperage in CC mode before striking an arc.
• Arc control adjusts inductance to optimize MIG arc performance, or Dig control for Stick.
• Stackable design can save valuable classroom or workshop space.
• Line voltage compensation keeps output power constant even if input power varies plus or minus 10%.
• Built-in 10-pin connector for direct hookup of Spoolmatic® 15A or 30A spool guns.
• Built-in 14-pin connector provides quick, direct connection for 14-pin 24 VAC Miller wire feeders and accessories.
• Fan-On-Demand™ operates only when needed reducing noise, power consumption, and the amount of airborne contaminants pulled through the machine.
