Why TIG?
Which TIG Welder is Right for You?
TIG can weld a variety of metals, including steel, stainless
steel, chrome-moly, titanium, aluminum, copper, brass
and more.
While Miller offers several choices of TIG welders,
finding the right one for you is as simple as answering a
few questions.
Other benefits of the TIG welding process include:
• No spatter, flux or slag
• ‘On the fly’ amperage control
• Flexibility
– Welds more metal types than any other process
– Ability to weld thin and thick material
• High-quality welds and highly aesthetic weld beads
1. What types of metal will you be welding? If you’ll be
welding all types of metal except aluminum, a DC only
machine, such as Miller Maxstar® welder will work for you.
If you plan on welding aluminum, you’ll need a TIG
welder with AC output. Miller’s Dynasty®, Syncrowave®
and Diversion™ 165 TIG welders all have AC/DC output
for welding any type of metal.
What is TIG?
2. What thicknesses will you be welding? Your answer to
this question will determine the power output you need.
See the chart on pages 12/13 to determine which machine
fits the thickness of materials you’ll be working with.
A TIG welder maintains an electric arc between a tungsten
electrode and the workpiece. The arc and molten puddle
are shielded from the atmosphere by an inert gas (typically
argon), thus the name TIG (Tungsten Inert Gas) or Gas
Tungsten Arc Welding (GTAW).
Because the electrode is not consumed in the welding
process, as it is in MIG or Stick welding, filler metal is
manually added as needed.
To precisely control the welding current (heat input),
operators use a remote foot pedal or fingertip control.

4. Where are you going to weld? Consider the surroundings
you plan to use your new TIG welder. What primary
power is available? Are there any size restrictions you will
encounter? Do you plan to move your machine often?

Why AC?
Key TIG Terms
AC TIG is generally used to weld aluminum and magnesium
materials. These metals instantly form oxides when exposed
to air. Before the parts can be welded, the oxide must be
removed. While it can be cleaned manually, the oxide will
quickly form again. Alternating current aids in removing
this oxide layer by cleaning the weld puddle.

• AC balance—controls the amount of oxide cleaning
(amperage time in Electrode Negative versus Electrode
Positive) which is essential for high-quality aluminum
welds. See page 6 for details.
• Alternating current (AC)—an electrical current that
reverses its direction at regular intervals.
• AC frequency—controls the width of the arc cone.
See page 6 for details.
• Auto-Line™ —allows for any primary input voltage within
a range, single- or three-phase with no manual linking,
providing convenience in any job setting.
• Direct current (DC)—flows in one direction and does not
reverse its direction of flow as does alternating current.
• Duty cycle—the duty cycle of a welding power source is
the amount of time you can weld at a given output
without overheating the power source. Duty cycle is
based upon a 10-minute period of time. For example,
if a machine is rated at 300 amps at 60% duty cycle, it
can weld at 300 amps for six minutes. For the remaining
four minutes, the power source needs to idle and cool.
• Fan-On-Demand™—internal power source cooling
system only works when needed, keeping internal
components cleaner.
• High frequency (HF) arc starting — provides
non-contact arc starting that eliminates tungsten or
material contamination.
• Lift-Arc™ —provides arc starting without the use of
high frequency.
• Line voltage compensation (LVC™)—maintains constant
output, even if input voltage varies by +/- 10%.
• Pulsing—switching between a high and low amperage
for additional control of heat input.

Unconventional wave provides
the punch of the peak
amperage, while reducing
overall heat input. Quick puddle
formation reduces weld time
— limiting heat input and
reducing weld distortion,
especially on thin materials.

Dynasty 350 and 700 provide advanced waveforms,
including Advanced Squarewave, Soft Squarewave,
Sine Wave and Triangular Wave (see page 6), as well as:
• Independent amplitude/amperage control to allow
EP and EN amperages to be set independently, precisely
controlling heat input to the work and electrode
• Extended AC balance (30–99%)
• AC frequency (20–400 hz)
DC TIG features:
• Exceptionally smooth and precise arc for welding
exotic materials
• High-speed DC TIG Pulse control capable of pulsing
5000 pulses per second for arc stability, reduced heat
input increased travel speeds

Weldcraft® torches
Miller recommends Weldcraft brand
TIG torches—every Weldcraft torch is
specifically engineered and assembled
with the finest materials. Both air- and
water-cooled torches are available. See
Weldcraft.com for more information.
Foot pedal and
fingertip control
Remote control capabilities
usually include output and
current control. The foot
pedal control operates like a gas
pedal in a car; the more it is pressed,
the more current that flows. Another
type which delivers more mobility is the
fingertip control that mounts
on the torch.
Coolmate™ coolers
Miller offers Coolmate coolers
for water-cooled TIG torches.
See MillerWelds.com for
more information.
Running gear
Miller offers running gear for the larger or water-cooled
systems, to allow them to be easily wheeled around the shop.
Other accessories available:
• Protective covers
• Remote foot pedals and fingertip controls
• Torch accessory kits
• Contractor kits
Complete packages include:
• Running gear
• Coolmate cooler
• Coolant
• Weldcraft torch
• Torch accessory kit
• Gas regulator and more…
