4.5 General instructions for use
Before starting, make sure you read, understand and apply the
safety instructions and other instructions included in the present
manual.
Below you will find a series of general indications that will
allow you initiating yourself in the world of welding and working
efficiently. In the present manual, instructions are provided with
regard to the rudiments of shielded-electrode welding of relatively
moderate difficulty in execution and regarding TIG welding having
a relatively greater difficulty. Take into account that welding on
professional level is a qualified and specialized activity. For further
information, refer to specialized books and regulated professional
training courses.

4.5.1 Control panel

Introduction
The machine is managed on the control panel. It is based on a
microprocessor managed by a specific application on a real-time
operating system. It consists of a 3x7 segment display, 34 LEDs,
the rotary encoder A and the 7 buttons B1, B2, C, D, E, F and G.
The operation is intuitive:
1. The rotary encoder A sets the parameter values.
2. The B1 and B2 buttons select parameters subject to adjustment.
3. With buttons C to F select welding modes and process
properties.
Instructions for use of rotary encoder A
Turning to the left lowers the value and turning to the right
increases the value. The range of values is automatically set by
software in relation to the selected parameter. For quick setting of
values, hold inward and turn. For small adjustments or final fine
adjustment turn without pressing.
Instructions for use of parameter selectors B1 and B2
Depending on the working mode, the application software will
select the different parameters that can be selected with buttons
B1 and B2. When you press B1 or B2, the indicator led will start
flashing indicating the selected parameter and the display shows
the parameter's setting value. With B1 the selection is moved to
the left and with B2 it is moved to the left.
Once the parameter is selected, the indicator led flashes for 5
seconds to review the value or to modify it with the encoder A.
After 5 seconds without modifying the parameter, the indicator
led turns off and the display shows the value of the main welding
current.
Instructions for use of welding modes and process properties
Each one 5 buttons C, D, E, F and G select the corresponding
modes and properties on the LEDs above them.
Each press of a button advances the selection.
When you get to the last one it will continue with the first one in
intuitive circular selection mode.
Button C: Welding Type
MMA: Selects the arc and stick welding mode.
DC: Selects the arc and TIG welding mode in direct current mode.

AC: Selects the arc and TIG welding mode in alternating current
mode.
DC Pulse: It is the DC mode to which pulse functions are added.
AC Pulse: It is the AC mode to which pulse functions are added.
Button D: Mode Operation
Manages the different modes of operation of the TIG welding
modes
2T: Two-stage welding mode. As a simplified introduction, when
the trigger is pulled there is a welding arc and when it is released,
the welding arc is interrupted.
4T: Four-stroke welding mode. As a simplified introduction when
the trigger is pulled the first time there is a welding arc and the arc
is maintained without holding the trigger down. When pressed a
second time the welding arc is interrupted.
Repeat 2T: It is the 2T mode with repeating functions. For mass
production and automation.
Repeat 4T: It is the 4T mode with repeating functions. For serial
production and automation.
Spot Welding: Spot welding mode. For discontinuous joints by
spot welding.
Button E: ARC Start
Manages arc striking procedures.
HF Start: Non-contact arc starting by injection of high frequency
and high voltage signal for TIG welding mode. Position the
electrode about 2mm from the part to ensure the appearance of
the priming arc.
Lift -ARC: Contact priming for TIG welding mode with minimal
impact on the part. It consists of two phases: touching the part
with the electrode and lifting the electrode to produce the welding
arc.
Anti-Stick: Arc ignition for coated electrode welding. Enables or
suppresses power failure when an electrode makes direct contact
with metal.
Button F: Gas Check / VRD
Gas Check: Opens the gas shut-off valve for TIG welding mode.
It is used to purge the air from the pipes and to check the correct
operation of the gas circuit.
VRD: Activates the 12Vdc welding vacuum voltage reducing
device for stick welding mode.
It is used for certain types of work in which VRD is required. If not
necessary it is recommended to disable the VRD as arc striking
is slightly more difficult.
Auto button:
This button is offered for users who are not trained to use the
machine professionally. Once pressed, only the main welding
current is adjusted and the software application imposes the most
probable welding parameters for that main current.
MMA parameter settings
These are the adjustable parameters in stick welding mode.
Current Ignition: Also known as 'Hot Start'. This is a brief increase
in energy when the electrode starts the arc. It is used to prevent
the electrode from sticking due to cold both the part and the
electrode itself. On the other hand, if a value is set too high, it
may be the case of piercing parts when welding thin thicknesses.
The setting value is in amps.
MMA Current: It is the main welding value. Adjust according
to the type of work taking into account position, type of union,
type of metals, thickness and diameter and type of electrode.
The adjustment value is in amps and this value is the one that
remains on the display by default. ARC Force: It is the increase
in energy that occurs dynamically while welding is being carried
out. Depending on the type of electrode, a drop break value will
be selected that will prevent the electrode from sticking to the
work piece.
Rutile type electrodes usually require low values, medium basic
