CST 280 Stick Welder, 1- & 3- Phase, 5 - 280 DC

The CST 280 is a durable yet lightweight Stick/TIG welding power source designed for construction industry. 280 amps of output is ideal for stick electrodes up to 3/16 in and TIG welding pipe and plate. Easy voltage changeover between voltage ranges through a two-position manual switch. Conveniently located on the rear panel, it simplifies voltage change in racks. Simple to operate with a process selector knob which automatically sets the proper dig setting on E6010 and E7018 electrodes providing superior stick performance. Lift-Arc start provides arc starting without the use of high frequency. Fan-On-Demand cooling system operates only when needed providing power efficiency and noise reduction. Stand-alone or rack-mounted for construction sites. Optional 4-pack racks, 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. Remote amperage control provided through 14-pin receptacle on front of the machine. This permits use of standard amperage control devices. Tweco- or Dinse-style connectors available. The Dinse-style includes one set of male connectors: the Tweco-style does not. Adaptive Hot Start for Stick Automatically increases output amperage at the start of a weld should the start require it and prevents the electrode from sticking and creating an inclusion.

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