ITW Miller 907719002 Dynasty 800 AC/DC TIG (GTAW) Power Source 400V

The ultimate precision AC/DC welding machine with total AC arc shaping capabilities. 

Main Features :

Advanced AC Squarewave arc with AC waveshaping controls. 

AC Balance Control range of 30–99% EN allows precise cleaning control and prolonged tungsten life. 

AC Frequency Control range of 20–400 Hz provides control for a focused arc. 

Independent AC Amperage Control allows the EP and EN amperages to be set independently. 

Average AC Amperage Control adjusts the calculated average amperage. 

Auto-Line™ - Allows for any input voltage hook-up (208–575 V, 1- or 3-phase) with no manual linking, 

Adjustable HF arc starting parameters - start amperage (amps), start time and start polarity (EP/EN) 

Program memory features 4 independent memory levels per process (AC/DC TIG and AC/DC Stick)  

Fan-On-Demand™ cooling system only operates when needed. 

HF arc starting provides non-contact arc starting that eliminates tungsten or material contamination 

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

Low OCV Stick™ reduces open-circuit voltage to 10-15 VDC when power not in use. 

Superior arc performance even on difficult to run electrodes like E6010. 

Optional TIGRunner® Packages.
