The Miller CST 208 ranks as one of the best in terms of maintenance, duty cycle, and performance. 

The CST 282 small design makes the welding machine to be flexible and work anywhere where there are 208 to 575 volts of AC power. It allows for the CST 282 to be used for a wide range of jobsites with no manual linking needed.
