Product Description

The Miller STI 203 is an inverter based, DC power source with a simple to use operator interface, providing only the necessary controls in a compact machine. Portable in the shop or at the job site, at 13kg the STI 203 easily moves from location to location.

Does not include Cables


Adaptive hot start - for stick starts automatically increase the output amperage at the start of a weld should the start require it. Prevents the electrode from sticking and creating an inclusion.

DIG control - allows the arc characteristics to be changed for specific applications and electrodes. Lower the DIG setting for smooth running electrodes like E7018 and increase the DIG
setting for stiffer, more penetrating electrodes like E6010.

Easy installation - no manual linking providing convenience in any job setting. Ideal solution for dirty or unreliable power. 

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

Remote amperage control provided through 14-pin receptacle on front of the machine. This permits use of the standard remote amperage control devices.
