DISCONTINUED - This product has been replaced by Miller CST 282 907810
Miller designed the CST 280 for Stick and TIG welding pipe and plate in the construction industry, and it's exceptional performance with difficult E6010 electrodes has made it a standby on jobsites all over the world. Weighing in at just 41 lbs, this compact welder is easy to move around, but packs 280 amps for superior Stick performance on pipes up to 3/16” in diameter.
- Superior stick arc performance even on the difficult-to-run electrodes like E6010.
- Adaptive Hot Start™ for stick arc starts automatically increases the output amperage at the start of a weld should the start require it. Prevents the electrode from sticking.
- Lift-Arc™ start provides TIG arc starting without the use of high frequency.
- Simple voltage-changeover switch saves time when changing primary voltage.
- Input voltage can be changed without removal from inverter rack or removal of machine case.
- Portable in the shop or at the jobsite — at 41 pounds the CST 280 is easily moved from location to location.
- Remote amperage control provided through 14-pin receptacle on front of the machine. This permits use of standard remote amperage control devices.
- Fan-On-Demand™ cooling system operates only when needed, providing power efficiency and noise reduction.
- Six-foot power cable included.
- Rack mountable for protection, storage and transportation of multiple power sources while using a single primary power cable.
