Pro-Set

™

feature (professional

settings) eliminates the guesswork

when setting weld parameters.

Use Pro-Set when you want

the speed, convenience and

confidence of pre-set controls.

Simply select the feature and

adjust until Pro-Set appears on

the display. The Pro-Set feature is

available for Balance, Frequency,

Pulse, and DIG parameters.

Sleep timer conserves electricity.

This programmable feature will

power down the machine if it sits

idle for a specific time.

Allows 208 – 575 V input voltage hookups.

Lift-Arc

™

starting provides x-ray clean

welds in AC or DC arc starting without

the use of high frequency.

Blue Lightning

™

high-frequency arc

starter for non-contact arc initiation.

Provides more consistent arc starts and

greater reliability compared to traditional

HF arc starters. Easy to set and increases

productivity.

Meter calibration. Digital meters can be calibrated to a

standard device for certification.

Wind Tunnel Technology

™

protects internal electrical

components from airborne contaminates, extending the

product life.

Fan-On-Demand

™

power source cooling system operates

only when needed, reducing noise, energy use and the

amount of contaminates pulled though the machine.

AC TIG Features

Extended AC balance (50–99%)

controls the amount of oxide cleaning

(amperage time in EN) which is essential

for high quality welds on aluminum.

AC frequency (20–400 Hz) controls

the width of the arc cone and the force

of the arc.

AC Waveforms

Advance Squarewave, fast

freezing puddle, deep

penetration and fast travel speeds.

Soft Squarewave for a soft

buttery arc with maximum

puddle control and good wetting action.

Sine wave for customers that

like a traditional arc. Quiet with

good wetting.

Triangular wave reduces the

heat input and is good on thin

aluminum. Fast travel speeds.

DC TIG Features

Exceptionally smooth and precise arc

for welding exotic materials.

Stick Features (AC/DC)

Tailored arc control (DIG) allows the

arc characteristic to be changed for

specific applications and electrodes.

Smooth running 7018 or stiffer, more

penetrating 6010.

Hot Start

™

adaptive control provides

positive arc starts without sticking.

AC frequency control adds stability for

smoother welds when AC Stick welding.

Stick-Stuck detects if the electrode is

stuck to the part and turns the welding

output off to safely and easily remove

the electrode. Menu selectable.
