Power source is warranted for 3 years, parts and labor.

Original main power rectifier parts are warranted for 5 years.

Allows for any

input voltage
hookup (208–575 V) with no manual linking,
providing convenience in any job setting.
Ideal solution for dirty or unreliable power.

NEW!

Meter Calibration allows meters to

be calibrated for certification.
120 V auxiliary power receptacle for

cooling system or small tools.

Wind Tunnel Technology

™

protects internal
electrical components from airborne
contaminants, extending the product life.

Fan-On-Demand

™

power source cooling
system operates only when needed,
reducing noise, energy use and the amount
of contaminants pulled though the machine.

TIGRunner

®

packages feature a

3.5 gallon (13.2 L) cooling system. The
cart is equipped with cylinder carrying
capabilities, filler rod holder, foot pedal
holder, torch and cable holders. A pullout
drawer provides additional storage for torch
consumables and tools. See page 6.

Programmable start parameters allow
independent starting conditions based
on process and memory selections
(amperage, time and polarity).

Program memory features 9 independent
program memories that maintain/save
your parameters.

High-frequency arc starter for
non-contact arc initiation.

Lift-Arc

™

start provides AC or DC arc

starting without the use of high frequency
Auto-Postflow calculates the length of

postflow time based on the amperage setting.
This eliminates the need to independently set
the postflow time for different amperages.
This feature preserves your tungsten and
prevents porosity.

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 additional stability when Stick
welding in AC for smoother welds.

AC TIG Features

Independent Amplitude/Amperage
Control allows EP and EN

amperages to be set independently
to precisely control heat input to the
work and electrode.

Extended AC balance (30–99%)
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.

High-Speed DC TIG Pulse Control

Pulse frequency capable of pulsing
5000 pulses per second. Pulsing
adds arc stability, reduces heat input
and warpage and can increase travel
speeds. Other parameters include
peak amperage, peak time and
background amperage.

Higher frequencies provide better arc control
and faster travel speeds.

Advanced Squarewave=Travel faster

Soft Squarewave= Maximum puddle control

Sine Wave= Traditional characteristics

Triangular Wave= Reduced heat input

Waveshaping controls maintain the point. The
benefits are: reduced heat input into your part,
smaller weld beads, better starting and more
control of the arc.

Easier to move because of size and weight.
Auto-Line™ allows the unit to operate on any
voltage. Single- or three-phase. Even generators!

Power requirement to operate is much less.
Smaller electrical service needed, smaller
breaker/fuses and power cord.

Accuracy and repeatability with all digital controls.
