Miller CST 280 220-230/460-575 V, Tweco #907244011

Designed for pipe and plate Stick/TIG welding in the construction industry, Miller packed 280 amps of superior Stick performance in a compact, durable package capable of welding up to 3/16” in diameter. Then they added LiftArc™ for smooth TIG starts without high frequency. That's a win in our book!

Superior Stick Arc Performance

Amperage control provided through 14-pin receptacle on front of the machine. Compatible with Wireless Remote Controls. Improve productivity, eliminate clutter and cord tangles in the work area. Eliminate cord failure and associated downtime/repair costs and extend the operator's welding range without adding cord extensions.

Lift-Arc™

Lift-Arc™ start provides TIG arc starting without the use of high frequency.

Simple Voltage Changeover

Simple voltage changeover switch saves time when changing primary voltage. Input voltage range can be changed without removal from inverter rack or removal of machine case.

Simple To Operate

Simple to operate with a process selector knob which automatically sets the proper dig setting on E6010 and E7018 electrodes providing superior stick performance.

Optional Digital Meter

Optional digital meter for more precise control when presetting or monitoring welding amperage.

Remote Amperage Control

Amperage control provided through 14-pin receptacle on front of the machine. Compatible with Wireless Remote Controls. Improve productivity, eliminate clutter and cord tangles in the work area. Eliminate cord failure and associated downtime/repair costs and extend the operator's welding range without adding cord extensions.

4 and 8 Pack Racks

Stand-alone or rack-mounted, commonly used in construction and shipyards, are available for multiple operator applications. All controls including the power switch are located on front of the machine for easy access.

Twist Lock Receptacles

Tweco- or Dinse-style connectors available. The Dinse-style includes one set of male connectors: the Tweco-style does not.
