MAIN MENU
TIG WELDING MODES
HF (High Frequency) – This mode allows the arc to start without touching
the tungsten to the metal being welded. It is also the preferred method when
using AC. When using HF the main causes of poor arc starts is contaminated
tungsten, too low of gas flow, or a poor ground clamp connection.
LIFT (Lift TIG) – This mode requires the tungsten to touch the metal, then
press the button and lift to start the arc. This setting is used where HF may
cause problems when used around sensitive electronics.
HF/LIFT TIG EASY – Ease of setup with optimum settings and the ability to
change the trigger mode (2T, 4T), set pulse up to 2Hz, and adjust welding
amps.
HF/LIFT TIG PRO – Control all TIG AC or DC welding parameters when a setting
is modified it saves automatically in the current program selection (PRO AC1,
2, 3, 4, 5)
MMA WELDING MODES
MMA EASY – Ease of setup with optimum settings and ability to choose the
electrode diameter then fine tune with the Amps.
MMA PRO – Control all stick welding parameters.
SETTINGS
Reset – Reset all welding parameters to defaults and reset welding timer.
Timer – Displays current total welding time for all welding modes.
Firmware Version – Displays the software version.
TIG WELDING SETUP
USING THE SWITCHED TIG TORCH
TIG Torch Switch Mode – Plug in the TIG torch then turn the machine on to
detect. If you do not detect the torch the amp control will not work.
Torch Push Botton Switch – Starts and stops the TIG welding ark. This button
will function differently depending on the trigger mode selected.
Finger/Thumb Wheel – Controls the welding amps when welding. 0 is the minimum
welding amps (10A), and 10 is whatever the machine is set to.
The amp value displays when welding and holds for 5 seconds after the arc
finishes.
USING THE FOOT PEDAL
Foot Pedal Mode – Plug in the foot pedal then turn machine on to detect
the foot pedal symbol will show in the TIG welding screen.
The foot pedal can also be used as a momentary switch by not detecting then
operating it in 2T or 4T modes.
Torch Selection – Both the non switched torch and switched torch can be
used with the foot pedal. If using the switched torch leave the plug to the
side.
MMA WELDING SETUP
MMA TORCH
MMA Welding Mode – In most MMA welding applications DCEP (Direct Current
Electrode Positive) is used. In some cases when welding very thin material
reversing the polarity to DCEN can be an advantage. (MMA TORCH NOT INCLUDED.)
TIG WELDING FUNCTIONS
Function
PRE FLOW (1-10 Seconds)
Purpose
This parameter operates in 2T and 4T HF TIG mode only and is used to provide
gas to the weld zone prior to striking the arc, once the torch trigger switch
has been pressed. This control is used to dramatically reduce weld porosity at
the start of a weld.
Function
START AMPS (10-200 Amps N/A EASY MODES N/A FOOT CONTROL)
Purpose
This parameter is used to set the start current for TIG. In 4T mode the
Initial Current remains on until the torch trigger switch is released after it
has been depressed. In 2T mode this is the Initial Current for the Up Slope
current ramp.
Function
UPSLOPE (0-10 Seconds N/A EASY MODES)
Purpose
This parameter is used to set the time for the weld current to ramp up from
INITIAL current to BASE current.
Function
WELDING AMPS (10-200 Amps)
Purpose
This parameter sets the welding current. In PULSE TIG mode, this parameter
sets the PEAK current.
Function
PULSE BASE AMPS (10-200 Amps)
Purpose
In PULSE TIG mode, this parameter sets the BASE current.
Function
DOWNSLOPE (0-10 Seconds N/A EASY MODES)
Purpose
Down Slope will ramp amps “down” from the welding amp value to the end amp
value to give time to fill the crater left at the end of the weld bead. Can
also be used in the 4T mode to help with heat control by briefly tapping the
switch to cool off the weld before tapping it again to restart the up slope
sequence before the arc reaches the end amp stage.
Function
PULSE TIME ON (10-90% NA EASY MODES)
Purpose
The pulse consists of two stages: Welding amps (upper /Peak) and Pulse amps
(lower/background current). This is represented by a % of total time the pulse
spends in the pulse amp stage of the cycle during one full pulse. The feature
can be used to increase or decrease pulse amp time relative to the welding amp
time of the cycle to help manage heat input.
Function
PULSE FREQUENCY (1-500Hz NA EASY MODES)
Purpose
Represented by Hertz (Hz), the pulse frequency defines the actual number of
times each second the pulse makes one complete cycle between welding amps
(peak/high amp value) and pulse amps (background/low amp value).
Function
HF ON/OFF
Purpose
HF – High Frequency Start which allows non contact starting of the arc or when
off (lift tig) requires contact with the metal to initiate the arc (for AC and
DC). (HF is selected when the symbol is not struck out) The lift start
function on the ALUMTIG 200 provides a cold electrode for safety and prevents
accidental starts.
Function
AC BALANCE (50-98% NA EASY MODES)
Purpose
Controls arc cleaning action when welding on AC. Adjusting the % electrode
negative (EN) AC wave controls the width of the cleaning zone surrounding the
weld. Lower percentage AC balance more cleaning action but less penetration.
Higher percentage AC balance less cleaning action but more penetration. PRO
TIP: Typically a range between 65% – 75% is used. 75% for new material 65% for
oxidised old material.
Function
AC FREQUENCY (50-98% NA EASY MODES)
Purpose
Governs the number of times per second that the current alternates in AC mode.
To achieve greater arc focus (constriction) and increase puddle agitation
while welding in AC mode, increase AC frequency. This allows pinpoint use on
thin materials and helps penetration on thicker materials. Ideal adjustment
range is usually between 80-120Hertz. For comparison most transformer welders
operate on 60 Hz. Greater arc control and stability can be achieved through
the higher frequency range offered by this welder. Lower Frequencies will
widen and soften the arc and reduce the level of control.
Function
AC WAVE FORMS
Purpose
SQUARE WAVE
This is the most commonly used waveform and produces great results in all
applications.
MODIFIED SQUARE WAVE
A modified square wave that has a slightly softer arc.
SINE WAVE
Mimics the wave form that is used on older transformer-style machines.
TRIANGLE WAVE
This produces a fast and sharp wave form and can help improve penetration on
thicker Aluminium.
Function
2T, 4T, TACK CONTROL (0.1 – 10 Seconds)
Purpose
2T MODE: Press and hold the switch. The program will cycle automatically.
When the switch is released, the arc will downslope and terminate with the
post-gas flow.
4T MODE: Switch is pressed and held to start the pre-flow then start amps
part of the cycle. When released, upslope begins and continues until the amps
are raised to the preset welding amps.
When pressed and held again, downslope starts and ramps down to the end amp
stage. If released before downslope ends program will cycle to main amps if
released after downslope ends the arc terminates, and post flow begins.
TACK CONTROL : Select this mode to control the arc on time for precision
tack welds.
MMA WELDING FUNCTIONS
Stick (MMA) PRO Functions
Function
HOT START (0-60 Amps)
Purpose
Sets the starting amps to reduce the sticking of the electrode during the arc
strike phase.
Function
WELD AMPS (10-200 Amps)
Purpose
Welding amps define the top limit of amps at which the machine has been
programmed to operate. Function ARC FORCE (0-99%) Purpose Controls the arc
response when an arc is held short and voltage begins to drop. Arc force
automatically compensates by modifying the volt/amp curve to maintain the
energy needed to weld. Represented as a percent of available arc force
amperage.
Stick (MMA) AUTO Functions
Function
ELEC DIA (2-5mm)
Purpose
Machine automatically adjusts amps relevant to the diameter of the electrode
being used.
Function
Amps Fine Tuning (-20-20%)
Purpose
Fine tunes the amps for the metal being welded.
