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, resulting in better directional control to help produce desired arc/weld bead characteristics.
Independent AC Amperage Control allows the EP and EN amperages to be set independently.
Average AC Amperage Control adjusts the calculated average amperage, maintaining the established EN to EP amperage ratio, along with the established AC Balance and Frequency.
Auto-Line Power Management Technology Allows for any input voltage hook-up (208–575 V, 1- or 3-phase) with no manual linking, providing convenience in any job setting.
Patented thread lock cable connectors and torch adapter (inset photo above) are designed for high-amperage applications and feature1/4-turn locking threads.
Adjustable HF arc starting parameters - start amperage (amps), start time and start polarity (EP/EN). Optimize the arc start based on tungsten electrode diameter, material thickness and shielding gas.
Program memory features 4 independent memory levels per process (AC/DC TIG and AC/DC Stick) with last procedure recall to maintain established parameters in each memory.
Inverter-based, power source has state-of-the-art operator interface allowing the user maximum set-up capabilities. Features more precise control of output paramters than traditional knobs and switches.
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.
Built-in Pulser enhances weld bead control for improved appearance and quality. Reduces burn-thru, coordinates the addition of filler
and reduces the warping effects of distortion by lowering the average welding amperage. High-speed pulsing capabilities
can narrow the weld and heat-affect zone while increasing travel speeds.
Built-in Sequence Control allows the entire weld sequence to be preset and controlled by the welding power source for greater accuracy and repeatability.
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.
115 V auxiliary power provides 15 amps of 115 volt power to operate a Coolmate™ coolant system, grinder or other small power tool.
Comes Complete With
(2) thread lock weld cable connectors
(1) water-cooled thread lock torch adapter
for #18 or #20 torches.
Note: Primary cord not included.
Free standard ground shipping within contiguous U.S.
