TERM DEFINITION AND EXPLANATION OF WELDING FEATURES AND TERMS
High Frequency Start This refers to the type of start in TIG mode. High Frequency (HF) provides an intense HF impulse from the internal HF board and point
gap that jumps the gap between the Tip of the Tungsten and the Work Piece. This means no contact is made directly to the metal to
start the arc. The foot pedal or torch switch is pressed and the arc will energize automatically after a brief HF spark is emitted. NOTICE:
The High Frequency Start feature does not pertain to AC welding and does not mean a welder will weld Aluminum or has an AC mode.
Hint: If HF starting is difficult make sure work clamp is directly connected to the part being welded before checking HF point Gap.
Hot Start This is used in Stick mode to provide an extra burst of Amps during the arc striking process. This helps to improve arc starting capabili-
ties and also helps to heat up the rod tip to prevent sticking and porosity at the start of the weld. The action is similar to “ Arc Force ” but
is limited in duration automatically by the unit ’ s programming. The value ranges from 0 - 100% over selected welding Amperage.
NOTICE: The Hot Start is limited by the remaining available welding amperage, regardless of setting. On 120V Hot Start may be limited.
Memory This is the ability of this unit to save different programmed settings. To save the setting, you should select a program # (sometimes
referred to as a “ channel ”) where you wish to save your settings before you begin to make any adjustments. After a program number
has been selected, you can make any adjustments you wish to the settings of the machine. Once you are satisfied with the programming
parameters, press the “ Save/Select ” arrow button in the Memory Display box and hold it for 3 seconds. While the button is held down, a
green LED will light up to indicate that the program has been saved. Hint: Any further adjustments to the programming will not be
automatically saved. If you need to resave the program after more adjustments have been made, simply press and hold the Save/Select
until the green LED lights again. Remember, to be careful not to save over old programs by changing the program number before. A
saved over program cannot be recalled or recovered if it has been saved over.
Pedal This refers to the foot pedal operation. The foot pedal is used to start the arc and increase or decrease the Amperage. The range of
Amperage controlled is limited at the panel by setting the maximum operating Amps. Usually set the max operating amperage 20% or
so above the maximum intended operating range. NOTICE: The pedal is used with TIG only. Do not use with Stick or Plasma Functions.
Post - Flow The Post - Flow is used for both TIG process and for Plasma Cutting. After terminating the Arc while TIG welding, the Argon gas should
flow briefly after the arc is terminated to prevent porosity in the weld puddle and to cool the weld and torch. This can be adjusted using
the Post - Flow feature. A good starting point is to set 1 second of Post - Flow for every 10 - 20 Amps selected for the weld. For Plasma
this should be used 1 second for every 10 Amps is sufficient for light cutting. Add more for extended cutting. This helps preserve the
torch and torch consumables.
Pre - Flow The Pre - Flow is used for the TIG process only. This is used to establish a protective pocket of shielding gas around the weld area
before starting the Arc preventing weld porosity or tungsten oxidation at the start. As a basic rule, any where from .5 to 1 second gener-
ally considered sufficient. However, if a large gas lens cup is used, the weld will require more Pre - Flow time, up to 3 seconds or more
to adequately purge the cup and the weld area. NOTICE: The Arc will not start until the Pre - Flow time is over.
Pulse The Pulse can used (for any single or combined purpose) to help control heat, deformation, puddle wicking or to improve the weld
aesthetics by offering a defined “ Dip ” point of the filler rod. The Pulse consists of three basic parameters: Base Amp Setting, Pulse Time
On (Balance) and Frequency. Of the three parameters, only Frequency is adjustable in each of the pre - programmed pulse programs.
However, the Pulse programming for Base - Amps and Pulse Time On has been carefully chosen to offer three useful, but distinct pulse
options. To fine tune each Pulse Program, the Pulse Frequency is fully adjustable from .1 - 150Hz.
Pulse Time On The amount of time that the stays in the Peak Amp and the Base Amp stage of the Pulse cycle can be skewed to favor more time in the
Peak stage, or less time in the Peak stage, in turn favoring more time in the Base stage. More time in the Peak stage offers a more fluid
puddle, while more time in the Base stage offers a less fluid puddle. For this welder, each of the three pulse programs the Pulse Time
On is fixed but is set to work in conjunction with the Base Amps % which is also fixed to offer 3 distinct but useful pulse programs.
Purge The Purge feature is used to safely allow gas to flow freely while setting the TIG or Plasma Regulator without having to trigger the torch
switch or foot pedal. Pressing the Purge button will lock on the Purge feature and allow it to flow until the Purge button is deselected.
Remote The TIG Arc cycle and amperage must be controlled either via Torch Switch or Foot Pedal. TIG can be operated without the remote in
the “ Live Lift ” mode, but the remote features allow you to signal the pre and post flow cycle, start and end of the weld cycle and increase
or decrease the welding amperage while welding. The foot pedal is a seamless way to control all of this manually. However, where foot
pedals aren ’ t practical, the torch switch can be used in either 2T mode or 4T mode to start and end the arc, or even increase or decrease
the amperage according to the programming set on the panel. NOTICE: The Live Lift Mode does not use a triggering mechanism of any
kind and the arc is started through touching the Tungsten to the metal.
Start Amps The Start Amps is used as a place where the Amperage is set once the arc starts. This can be set high for more aggressive starts, or low
for soft, easy starts. Usually softer starts are preferred for steel and stainless. Hint: Whether using the foot pedal or the torch switch, the
size of the Tungsten will affect minimum low amp starts. Although the unit is rated for 5 Amp starting, 5 Amp starts are best achieved
with a 1/16” tungsten or smaller. It ’ s not impossible to start at 5 Amps with larger Tungsten, but the arc will be less easily struck and
stabilized with larger Tungsten diameters. For 3/32” or 1/8” Tungsten, try setting Start Amps to 10 to 15 Amps for best results.
Spot The Spot Weld feature is used primarily to help improve tack size consistency. This feature is used for TIG only and is not meant to be
used with traditional spot weld tongs, or similar mechanisms. The idea of the spot weld is to provide a controlled Arc - On time so that
the weld will be repeatable and uniform. This is good for setting up auto body panels, tacking exhaust tubing or filling small plug welds.
TIG Start This unit allow the user to choose from three distinct TIG Arc Starting Styles. The Lift Start is a contact type of arc starting method,
which creates an arc once the Tungsten is quickly snapped up and away from the work piece. However, a remote (a foot pedal or torch
switch) is required to turn on power output to the Tungsten. This is used in many places where HF is not allowed or could interfere with
electronic equipment. Live Lift is similar to the Lift Start, but the Live lift means the Tungsten stays live and power is always present at
the Tip of the Tungsten. Since no remote is required, the arc must be broken by quickly rotating the wrist and snapping the Tungsten
up and away from the work. The High Frequency start is only able to be used with the torch switch or the foot pedal. This type of start
is usually preferred since the Tungsten is held off the metal slightly and the pedal or torch switch is triggered to initiate the HF spark,
providing a pilot path for the arc to jump across once the HF establishes continuity with the work piece. NOTICE: If selected, the Live Lift
Start feature may cause accidental arc flashes if the Tungsten is not properly insulated from the work piece.
