Introduction

Thank you for buying our product. In order to get the best performance out of the plant and ensure the maximum lifespan of its parts, the use and maintenance instructions contained in this manual must be read and strictly complied with, as well as the safety instructions contained in the rele- vant folder. If repairs to the plant are required, we recommend that our clients contact our service centre workshops, as they have the necessary equipment and personnel that are specifically trained and constantly updated. All our machines and equipment are constantly developed and so changes may be made in terms of their construction and features.

• TIG

- Excellent TIG welding characteristics.

High frequency arc striking of TIG welding, precise and efficient even from long distance.

- Using special TIG torches allows remote adjustment of welding current directly from the torch.

The diameter of the electrode used is set to allow greater control of the ignition and dynamics of the arc.

Standard built-in pulsation (from 0,5 to 2000 Hz) with provision for entering the SYN Pulse function.

Square, mixed, sinusoidal, or triangular wave shape selector.

Square welding wave frequency balancing / regulation and “Balance Plus”.

• MMA

The VRD (Voltage Reduction Device) can be activated, which reduces voltages to below 12 V, which means that the welding machine can be used in ambient conditions in which there is a high electrical risk, thereby providing maximum operator safety.

“Arc Force” adjustable to select the best dynamic characteristics for the welding arc.

- “Hot Start” adjustable to improve ignition with particularly difficult electrodes.

- Anti-sticking function to avoid the electrodes sticking.

MATRIX 2200 AC/DC

•

The PFC device makes the wave form of the current absorbed sinusoidal, which results in no harmonic disturbance on the mains and optimisation of absorption, which allows you to use the generator’s full power with a 16 A fuse, as well as ensuring greater protection of the welding machine against fluctuations in the power supply voltage.

MATRIX 3000 AC/DC R

• Suitable for use on all robotic systems.

•

Optional “RoboMAT 1” interface that handles all process start/ stop signals, regulation of the principal welding parameters, and also acts as a flexible, efficient interfacing system that meetsall Analogue / Digital connection requirements.

Usage limits (IEC 60974-1)

The use of a welder is typically discontinuous, in that it is made up of effective work periods (welding) and rest periods (for the positioning of parts, the replacement of wire and underflushing operations etc. This welder is dimensioned to supply a I2 max nominal current in complete safety for a period of work of X% of the total usage time. The regulations in force establish the total usage time to be 10 minutes. The work cycle is considered to be X% of this period of time. If the permitted work cycle time is exceeded, an overheat cut-off occurs to protect the components around the welder from dangerous overheating. Activation of thermal protection is signaled by “t° C” flashing on control panel display (for further information see the MTA control panel manual). After several minutes the overheat cut-off rearms automatically and the welder is ready for use again.

Installation

The installation site for the system must be carefully chosen in order to ensure its satisfactory and safe use. The user is responsible for the installation and use of the system in accordance with the producer’s instructions contained in this manual. Before installing the system the user must take into consideration the potential electromagnetic problems in the work area. In particular, we suggest that you should avoid installing the system close to:

• Signalling, control and telephone cables.

• Radio and television transmitters and receivers.

• Computers and control and measurement instruments.

• Security and protection instruments. Persons fitted with pace-makers, hearing aids and similar equipment must consult their doctor before going near a machine in operation. The environment in which the equipment is installed must be suitable for the casing’s protection level. This system is cooled by means of the forced circulation of air, and must therefore be placed in such a way that the air may be easily sucked in and expelled through the apertures made in the frame. The welding unit is characterised by the following levels:

•

Protection level IP 23 S indicates that the equipment can be used both indoors and outdoors.

• Use class “S” means that the equipment can be used in condi-

tions subject to heightened electrical shock.

Connection to the electrical supply

Connection of the machine to the user line (electrical current) must be performed by qualified personnel. Before connecting the welding machine to the mains power supply, make sure that rated voltage and frequency correspond to those provided by the mains power supply and that the welding machine’s power switch is turned to “O”.

MATRIX 2200 AC/DC • Single-phase power supply

Use the welder’s own plug to connect it up to the main power supply. Proceed as follows if you have to replace the plug:

•

2 conducting wires are needed for connecting the machine to the supply.

• The third, which is YELLOW GREEN in colour is used for making the “GROUND” connection.

MATRIX 3000 AC/DC - AC/DC R • Three-phase power supply

The four-pole cable supplied with the system must be used for the connection to the mains power supply. This cable is made up of:

•

Three conductors that are used to connect the machine to the power supply.

•

The fourth, which is YELLOW-GREEN, is used to form the “GROUND” connection.

Connect a suitable load of normalised plug (3p+t) to the power cable and provide for an electrical socket complete with fuses or an automatic switch. The ground terminal must be connected to the ground conducting wire (YELLOW-GREEN) of the supply.

Table 2 shows the capacity values that are recommended for fuses in the line with delays.

NOTE: Any extensions to the power cable must be of a suitable diameter, and absolutely not of a smaller diameter than the special cable supplied with the machine.

TIG welding

In the TIG process welding is achieved by melting the two metal pieces to be joined, with the possible addition of material from the outside, using an arc ignited by a tungsten electrode. The molten bath and the electrode are protected by and inert gas (for example, Argon). This type of welding is used to weld thin sheet metal or when elevated quality is required.

1) Connecting the welding cables (Fig. C):

• Connect the gas hose to the Argon cylinder.

• With the machine switched off:

Connect the ground cable to the snap-on connector marked + (positive).

Connect the relative ground clamp to the workpiece or to the workpiece support in an area free of rust, paint, grease, etc..

Connect the TIG torch power cable to the snap-on connector marked - (negative).

Connect the torch gas tube to the connection (Pos. 3, Fig. A).

Insert the torch button connector in the 6 poles holder (Pos. 4, Fig. A).

2) Switch the welding machine on by moving the power supply

switch to I (Pos. 6, Fig. A).

3) Make the adjustments and select the parameters on the con-

trol panel (for further information see the MTA control panel manual).

TIG WELDING WITH “Lift” TYPE STRIKING

4a) Open the gas cylinder and flow regulator. 5a) Put the electrode at the point at which welding is to begin, put

the TIG torch at an angle so that the edge of the gas nozzle is not on top of the piece to be welded, keeping contact between the point of the electrode and the piece to be welded

(Fig. D-1). 6a) Press the torch button. 7a) The “Lift” function strikes the arc when the TIG torch electrode

comes into contact with the workpiece and is then removed

(Fig. D-2) 8a) Carry out TIG welding (Fig. D-3). To end welding:

•

Lift the torch slowly, at a certain point the welding current decreases, and then stop.

•

The welding machine follows an automatic down slope along with extinguishing of the arc.

9a) When finished welding remember to shut off the gas cylinder.

TIG WELDING WITH HIGH FREQUENCY STRIKING (HF)

4b) Open the gas cylinder and flow regulator. 5b) Put the electrode at the point at which welding is to begin, put

the TIG torch at an angle so that the edge of the gas nozzle is

not on top of the piece to be welded, keeping a 2-3 mm gap

between the point of the electrode and the piece to be weld-

ed (Fig. E-1). 6b) Press the torch button. 7b) The voltaic arc strikes even without contact between the TIG

torch electrode and the workpiece (Fig. E-2). 8b) To continue welding put the torch back in its normal position

(Fig. E-3).

IMPORTANT: The high frequency switches off automatically after switching on.

PART TO BE WELDED

The part to be welded must always be connected to ground in order to reduce electromagnetic emission. Much attention must be afforded so that the ground connection of the part to be welded does not increase the risk of accident to the user or the risk of damage to other electric equipment. When it is necessary to connect the part to be welded to ground, you should make a direct connection between the part and the ground shaft. In those countries in which such a connection is not allowed, connect the part to be welded to ground using suitable capacitors, in compliance with the national regulations.

WELDING PARAMETERS

Table 3 shows the currents to use with the respective electrodes for TIG welding. This input is not absolute but is for your guidance only; read the electrode manufacturers’ instructions for a specific choice. The diameter of the electrode to use is directly proportional to the current being used for welding.

Table 3

1,2 1,6 2,4 3,2 4,0

10 ÷ 80

70 ÷ 150 140 ÷ 250 225 ÷ 400 300 ÷ 500

Electrode welding (MMA)

The welding electrode is used to weld most metals (various types steel, etc.),for which rutilic and basic electrodes are used.

1) Connecting the welding cables (Fig. F): Disconnect the machine from the mains power supply and con-

nect the welding cables to the output terminals (Positive and Negative) of the welding machine, attaching them to the clamp and ground with the polarity specified for the type of electrode being used (Fig.F). Always follow the electrode manufacturer’s instructions. The welding cables must be as short as possible, they must be near to one another, positioned at or near floor level. Do not touch the electrode clamp and the ground clamp simultaneously.

2) Switch the welding machine on by moving the power supply

switch to I (Pos. 6, Fig. A).

3) Make the adjustments and select the parameters on the control panel (for further information see the MTA control panel manual).

4) Carry out welding by moving the torch to the workpiece. Strike the arc (press the electrode quickly against the metal and then lift it) to melt the electrode, the coating of which forms a protective residue. Then continue welding by moving the electrode from left to right, inclining it by about 60° compared with the metal in relation to the direction of welding.

PART TO BE WELDED

WELDING PARAMETERS

Table 4 shows some general indications for the choice of electrode, based on the thickness of the parts to be welded. The values of current to use are shown in table 5 with the respective electrodes for the welding of common steels and low-grade al

loys. These data have no absolute value and are indicative data only. For a precise choice follow the instructions provided by the electrode manufacturer.

Table 4

WELDING THICKNESS (mm) Ø ELECTRODE (mm)

30 ÷ 60 40 ÷ 75

60 ÷ 110

95 ÷ 140 140 ÷ 190 190 ÷ 240

The current to be used depends on the welding positions and the type of joint, and it increases according to the thickness and di

mensions of the part. The current intensity to be used for the different types of welding, within the field of regulation shown in table 5 is:

• High for plane, frontal plane and vertical upwards welding.

• Medium for overhead welding.

•

Low for vertical downwards welding and for joining small pre-

heated pieces. A fairly approximate indication of the average current to use in the welding of electrodes for ordinary steel is given by the following formula:

I = 50 × (Øe - 1)

Where: I = intensity of the welding current Øe = electrode diameter Example: For electrode diameter 4 mm

I = 50 × (4 - 1) = 50 × 3 = 150A

Maintenance

ATTENTION: Before carrying out any inspection of the inside of

the generator, disconnect the system from the supply.

SPARE PARTS

Original spare parts have been specially designed for our equipment. The use of non-original spare parts may cause variations in performance or reduce the foreseen level of safety. We decline all responsibility for the use of non-original spare parts.

GENERATOR

As these systems are completely static, proceed as follow:

•

Periodic removal of accumulated dirt and dust from the inside

of the generator, using compressed air. Do not aim the air jet

directly onto the electrical components, in order to avoid dam-

aging them.

• Make periodical inspections in order to individuate worn cables

or loose connections that are the cause of overheating.

Optional

The remote controls can be only used in the 2-STROKE and 4-STROKE welding modes.

MANUAL REMOTE CONTROL

WARNING: When using the machine for TIG welding it is OBLIGA-

TORY to use the kit for simultaneously use – CEA code n° 460056.

Weld current can be measured at a distance by connecting up this control. The display will show the previous maximum weld current value set on the welder. The remote control will adjust welding current from the minimum to this value (for further information see the MTA control panel manual). Just turn the adjustment knob on the welder to change the maximum output value.

FOOT SWITCH

The foot switch replaces the torch button and the welding current setting knob. The display will show the previous maximum weld current value set on the welder. The pedal will adjust the welding current from the minimum to this value (for further information see the MTA control panel manual). Just turn the adjustment knob on the welder to change the maximum output value.

NOTE:

•

To use the pedal control correctly, set the “welding mode” to 2-STROKE and then the welding parameters SLOPE UP time to 0 sec., SLOPE DOWN time to 0 sec.

• When using the machine for TIG welding the operator can use the torch button to start the weld and the pedal to regulate the welding current remotely..

AIR AND/OR WATER-COOLED TORCH UP/ DOWN

The up/down torch replaces the current setting knob on the front of the welder. Press right (+) and left (-) button to adjust the active parameter. With this kind of torch, it is also possible to scroll the saved programmes by pressing the two (+) and (-) buttons. Turn the knob to scroll the programmes until an empty and unused programme is found.

NOTE: Programme sequences can be created by placing an empty programme between saved ones.

NOTE: The value shown on the display during welding represents the effective current output with all types of control.

The digital control unit of the generator is fitted with a control recognition device which allows it to identify which device is connected and take action accordingly. To allow the command recognition device to work correctly, connect (with the machine switched off) the required accessory to the relative connector and then switch on the welding machine with the on/off switch.

NOTE: It is not possible to memorize or open programmes when the remote controls are connected (except for the torch with UP/DOWN commands).

If a remote control is connected (followed by self-acknowledgement procedure) the machine will automatically return to the manual-welding phase if it has been pre-set for automatic welding.

The pointing out of any difficulties

and their elimination

The supply line is attributed with the cause of the most common difficulties. In the case of breakdown, proceed as follows:

1) Check the value of the supply voltage

2) Check that the power cable is perfectly connected to the plug and the supply switch

3) Check that the power fuses are not burned out or loose

4) Check whether the following are defective:

• The switch that supplies the machine.

• The plug socket in the wall.

• The generator switch.

NOTE: Given the required technical skills necessary for the repair of the generator, in case of breakdown we advise you to contact skilled personnel or our technical service department.

Digital interface PCB replacement

• Unscrew the 4 screws fastening the front rack panel.

• Remove the adjustment knob.

• Extract wiring connectors from digital interface PCB.

• Unscrew small supporting columns.

• Remove digital interface PCB by lifting it out of its supports.

• Proceed vice versa to assemble new digital interface PCB.

Introduction

This manual describes the functions on and how to use the following control panels:

• MTA 22

• MTA 30

Control panel

■ VRD

The Voltage Reduction Device (VRD) is a safety device that reduces the voltage. It prevents voltages forming on the output terminals that may pose a danger to people. Two-tone LED (off - red - green) indicates enabling of the VRD device. The standard, preset settings for the firm do not activate the VRD function on the welding machine and so this LED is normally off. To activate the VRD device, see the relevant paragraph.

■ WELDING PROCESS

The MATRIX welding machine offers 4 TIG/Electrode welding processes. Each time the button is pushed, the welding machine switches to select the welding process indicated by the LED that stays lit, in the following order:

L1 TIG AC with HF ignition L2 TIG DC with HF ignition L3 TIG DC with “Lift” type ignition L4 ELECTRODE (MMA)

■ ELECTRODE DIAMETER

For TIG welding with HF ignition, it allows you to use the relevant key to set the diameter of the tungsten electrode used, and/or to change it using the ENCODER knob, in order to achieve the best control of the AC arc in a synergic manner.

WARNING: The electrode diameter CANNOT be selected when the welding machine is set for the SPECIAL configuration.

■ WELDING MODE

The MATRIX welding machine offers 4 welding modes. Each time the button is pushed, the welding machine switches to select the welding mode indicated by the LED that stays lit, in the following order:

L5 2 STROKES L6 4 STROKES L7 CYCLE L8 SPOT WELDING

L5 L6 L7 L8

L5 2 STROKES

When the torch button is pushed welding begins starting with the INITIAL CURRENT (if SLOPE UP is selected), while when it is released welding ends when the FINAL CURRENT is reached (if SLOPE DOWN is set).

L6 4 STROKES

TIG welding takes place as follows:

• When the torch button is pushed welding begins at the INITIAL

current.

•

When the torch button is released the SLOPE UP process is carried out (if applicable) and the current returns to the PRINCIPAL value I1 .

•

When the torch button is pushed the SLOPE DOWN process is carried out (if applicable) and the current returns to the FINAL value.

• When the button is released the welding cycle ends.

L7 CYCLE

When this function has been activated, TIG welding takes place as follows:

• When the torch button is pushed welding begins at the INITIAL

current.

•

When the torch button is released the SLOPE UP process is carried out (if applicable) and the current returns to the PRINCIPAL value I1 .

• When the torch button is pressed and released within less than

1 second the welding current goes to the CYCLE value ( I2 ), and by repeating this operating you can move between the two current levels ( I

1 ), ( I2 ) an infinite number of times.

•

When the torch button is pushed and held down (for longer than 1 second) you exit the cycle, the SLOPE DOWN process is carried out (if applicable) and the current returns to the FINAL val-

ue. When the torch button is released the welding cycle ends. This welding mode is especially indicated for welding profiles with different thickness, where continuous current variation is required. Also, when welding aluminium, it allows you to have a higher initial current, thereby facilitating pre-heating of the workpiece.

L8 SPOT WELDING

This can be used by pushing the torch button to spot weld for a preset period of time (in seconds) at the end of which the arc switches off automatically. The tack welding function is divided into 3 types:

• TIG AC and TIG LIFT DC tack welding.

• TIG HF DC tack welding with a single coldTack point.

• TIG HF DC tack welding with a Multi-ColdTack function. See the relevant paragraphs in the subsequent pages of this manual.

■ DISPLAY

Displays the selections made using the various Keys (with corresponding LED on or flashing) and regulated using the ENCODER knob.

The

button can also be used to view:

L32 AMPERE (CURRENT )

•

When the machine is in stand-by, the Amps (A) set.

• When the machine is welding the real Amps (A) at

which the operator is actually welding.

WARNING: LED L32 switched on and steady.

L33 VOLT (VOLTAGE)

•

The actual VOLTS (V) at the welding clamps (the value displayed CANNOT BE CHANGED OR REGULATED).

WARNING: LED L33 switched on and steady.

■ ENCODER knob

This is used to regulate and change the welding parameters, according to which LED is switched on and the value shown on the DISPLAY, which is necessary for the machine to work correctly.

■ SAVE “MEM”

Used to save the parameters for the welding programs.

■ PROGRAM “PRG”

Used to call up welding programs.

■ WAVE

During TIG AC welding with HF ignition, it makes it possible to control the following wave shapes:

L24 DYNAMIC TIG L25 SPEED TIG L25 COLD TIG L26 SOFT TIG

WAVE

L24

L25 L26

L24 DYNAMIC TIG

Square wave: highly dynamic arc for all applications.

WARNING: LED L24 switched on and steady.

L25 SPEED TIG

Mixed wave: excellent penetration with high welding speed and low electrode consumption.

WARNING: LED L25 switched on and steady.

L25 COLD TIG

Triangular wave: low heat generation with reduced distortion, ideal for minor thicknesses.

WARNING: LED L25 switched on and flashing.

L26 SOFT TIG

Sinusoidal wave: gentle, soft arc with low noise, ideal for average thicknesses.

WARNING: LED L26 switched on and steady.

■ BALANCING and FREQUENCY

During TIG AC welding with HF ignition, it makes it possible to set one of the following parameters, using the relevant key:

L30 BALANCING of the TIME and

AMPLITUDE of the AC welding current (BALANCE PLUS)

L31 FREQUENCY of the AC welding

current

L30

L31

L30 BALANCING of the TIME and AMPLITUDE of the AC

welding current (BALANCE PLUS)

It is possible to adjust both the time (t) and the amplitude of the current (I) independently or simultaneously, using positive or negative values for the time the electrode stays in place. These settings ensure perfect control of penetration and cleanliness, with a drastic reduction in side incisions.

L31 FREQUENCY of the AC welding current

The high frequency makes it possible to weld minor thicknesses with excellent results, while the low frequency is ideal for welding average thicknesses, or where edge preparation is poor.

WARNING: LED L31 switched on and flashing.

■ PULSE

When using one of the 3 TIG welding processes, it makes it possible to set one of the 4 pulsation modes available on the welding machine, using the relevant button:

2) Turn the ENCODER Key (E) anticlockwise until the DISPLAY (D) shows 3 dashes.

3) Press and release the “PRG” PROGRAM key (T2) and the machine goes back to the initial operation condition.

4) You can now set or edit the individual parameters or create new programs.

5) Rotate the ENCODER Knob (E) to scroll the programs until you find an empty, unused program slot.

Calling up saved programs

1) Hold the “PRG” PROGRAM Key (T2) down (about 3 seconds) until the DISPLAY (D) shows the number of the program selected flashing (e.g. Pr 6).

2) Turn the ENCODER Knob (E) until the DISPLAY (D) shows the program number (flashing) you wish to call up (e.g. Pr5).

NOTE: If when you are rotating the ENCODER knob (E) to look for a saved welding program to call up the MTA panel does not have any LEDs switched on without flashing, this means that the welding program you are trying to call up has not been saved and, as a result, cannot be called up!

3) Press and release the “PRG” PROGRAM key (T2) to call up the program number selected.

4) You can now carry out PROGRAMMED welding.

Viewing the parameters set

1) Call up the program required (see the “Calling up saved programs” paragraph).

2) Press and release the WELDING PARAMETERS SELECTION Key (T10) to view the parameters set in sequence.

3) Hold the WELDING PARAMETERS SELECTION Key (T10) down for more than 1 second to go back to the program selected.

NOTE: If the parameters set are edited, you automatically exit programming.

Activating the VRD device

To activate the VRD device, which must be done when the welding machine is switched off:

1) Use a suitable screwdriver to unscrew the 4 screws that fix the MTA control panel to the welding machine.

2) Position JUMPER W1 on the DIGITAL INTERFACE BOARD in the correct position, following the instructions given in Figure A.

3) Use a suitable screwdriver to tighten the 4 screws that fix the MTA control panel to the welding machine.

4) Start the welding machine by pushing the switch on the rear panel to position I.

FIG. A

2000HB06

When the MTA control panel switches on the VRD LED will come on and will be GREEN, which means that the VRD function is on.

To “deactivate” the VRD device and therefore start to weld, follow this simple procedure: First touch the workpiece with the electrode, then detach it and ignite the arc within a MAX of 0,3 sec- onds, otherwise if this time is exceeded the VRD device starts and prevents welding.

During welding the VRD LED turns RED, which does not indicate any malfunction on the welding machine, but that the VRD device has been deactivated to allow welding.

Auxiliary functions

“Energy saving”

This function manages correct functioning of the cooling fan and cooling equipment that only run when strictly necessary, that is:

• FAN MOTOR - The fan is activated when:

During welding or for a certain period of time after this is finished.

When the thermostat intervenes or for a certain period of time after it has just been reset.

• COOLING DEVICE - The cooling device is activated:

For a few seconds when the machine switches on. This oper

ation is used to make the cooling liquid circulate through the plant at the correct pressure. Call the technical service department if, when the cooling system is switched off, the error does not disappear from the DISPLAY (D).

During welding or for a certain period of time after this is finished.

Factory default

WARNING: This operation results in complete resetting of all pa-

rameters to the factory settings.

To reset the settings, you must:

• When the welding machine is off, push and hold the WELDING PROCESS SELECTION (T7) and WELDING MODE SELECTION (T9) keys down together.

•

Switch on the welding machine and hold down the keys until the DISPLAY (D) reads 80.

• Release the two keys.

• The reset procedure has now been completed successfully.

The equipment is protected against problems and if any arise the DISPLAY shows fixed or flashing (error code) messages (depending on the type of error) that serve to inform the operator that a fault has occurred in the equipment (see table 1). The table provides a summary of all the error conditions that may arise on the equipment and, if possible, what the operator must do to attempt to resolve the problem.

Automatic reset error: once the alarm condition has been resolved the equipment starts working again and the operator can weld again!

PLEASE NOTE: If the fault persists look for the cause of the fault and contact our technical assistance department if necessary.

All of this is necessary to allow our technical assistance department (which must be contacted each time error messages appear on the equipment’s operator interface) to resolve problems more easily, as quickly as possible and thanks to the user’s reports, also because, in the meantime the machine will not allow the operator to do their work.

Display Diagnosis

E01

PRESSURE SWITCH

This message appears when the cooling equipment is connected to the machine and its pressure switch does not close due to a lack of pressure in the hydraulic circuit. Automatic reset error.

E02

OVER VOLTAGE

This message appears when the power supply voltage for the MATRIX 3000 AC/DC - AC/DC R exceeds 500V. If the fault persists look for the cause of the fault and contact our technical assistance department if necessary. Automatic reset error.

E03

UNDER VOLTAGE

This message appears when the power supply voltage for the MATRIX 3000 AC/DC - AC/DC R drops below 280V. If the fault persists look for the cause of the fault and contact our technical assistance department if necessary. Automatic reset error.

t°C

THERMAL PROTECTION

The welding stops due to an excessively high temperature (thermostat activated). Automatic reset error.

WARNING: The MATRIX 2200 AC/DC welding machine has a built-in electronic protective device to deal with fluctuations in mains voltage that switches the machine off automatically (voltage exceeding 300 V), without indicating any type of error or warning message for the operator. Subsequently it starts functioning again automatically when the voltage has dropped to below the value indicated above.
