TIG Arc Starting, Remote Functions and Operation

The TIG arc start can be performed in three basic ways.
The first and primary arc starting method used is High Frequency Start. HF
start is a contactless start which is performed by holding the Tungsten off
the metal about 1/8" or less and using the remote to activate the HF which
will send a high Voltage impulse to the Tungsten, causing the arc to jump
and create continuity to the work, allowing the inverter to kick in and put
out a normal welding arc. This is the most preferred way of starting, espe-
cially with Aluminum. The tip of the Tungsten is not easily contaminated
this way, and it requires little skill to perform. While this unit technically is
How Do I Perform an HF Start?
 Place the point of the tungsten 1/8" or less over the work piece.
 Press the torch trigger or foot pedal, and the HF spark will be emit-
ted. It may appear as small sparks or lighting if the arc doesn't start
immediately. (If Live Lift is used, no pedal or trigger is required.)

Once continuity establishes, the welding arc will begin. You may
begin to advanced the torch when a puddle forms. Maintain 1/8"
height or less while welding.

How Do I Perform a Lift Start?

Rest the edge of the cup on the work piece so that the tungsten is
slightly off the work. Press the trigger or foot pedal. Quickly rotate
the tungsten to the work using the cup edge as a pivot.
 A small spark may be noticed as it touches. Once the Tungsten
touches, quickly and seamlessly rotate the cup back to draw an arc.
 Raise the cup to establish the arc to 1/8" or less in height.
 Allow the puddle to form and move the torch forward maintaining
1/8 or less height.

considered an HV start, it electronically simulates the HF start. It is re-
ferred to HF on the Function line of the machine to eliminate confusion by
the average user, but in the more technical background menu, it refers to
HV start. For the purpose of the manual, HF and HV are treated as the
same thing.
The second method is Lift Start which requires direct, purposeful contact
with the surface of the metal to create continuity followed by a quick lift-off
of the Tungsten to strike the arc. To understand how this works, when the
Tungsten is touched to the metal, there is a small current supplied to the
tip. At the time the Tungsten is lifted up, the welder senses the break of
continuity. Then, the inverter sends full output to the Tungsten tip as the
arc is established through the small spark created by breaking continuity.
This form of Arc Starting is used when people need to start an arc without
the use of an HF energy being present which can interfere with sensitive
electronics nearby. It works well with steel, stainless and similar metals. It
can work with Aluminum, but there is a chance of contamination of the
Tungsten and more rapid wear.
The third method is the Scratch Start method. This method involves a full
current start with a live Tungsten that requires the Tungsten to be lightly,
but quickly scratched on the metal, or drug quickly over the filler wire
which is temporarily touching the metal to draw and strike up the arc. The
quick brush across the metal can create a skipping motion if not performed
correctly which can result in a stuck Tungsten. This is the least efficient
method, but is in common use in the field with basic DC TIG rigs that have
no automatic control of shielding gas and use a gas-valve torch. However
this unit is not equipped with this type of function, though Live Lift can
function similarly while also providing automatic control over the gas. Live
lift can also be used with a TIG Rig with a valve controlled torch, but the
solenoid will need to be covered when not in use. Use the plastic dust
caps that are included with the unit and are installed on the fittings of the
welder to cover the holes when the solenoid gas valve will not be used.
Remote Function and Operation.
Both HF Start and Lift Start mode on this Typhoon TIG welder need either
a torch switch, a foot pedal (or similar Amp-trol mounted on the torch
handle), or a torch with both a mounted switch and a separate torch switch
button for special remote modes. However, the Live Lift function requires
no remote to start the arc since the Tungsten is always live. The Lift Start
with a remote switch or control provides a safe and effective means of
starting the arc without HF while still being able to the weld with either the
pre-programmed settings offered by the Remote 2T/4T type of control with
a torch switch or with a foot pedal to control both start and the range of
Amperage selected. When used normally with the foot pedal or torch
mounted Slider Amp Control, the Remote function should be set only to
the Pedal mode. When the Pedal mode is used, many of the parameter/
graph line functions will be nullified due to conflicts with proper pedal
operation and function. These nullified parameters will be items such as
Up Slope, Down Slope and End Amps. If the parameter is nullified, it is not
adjustable. The nullified parameter will be grayed out and listed as Not
Available (N/A). Each available parameter can be adjusted and fine tuned
