INTRODUCTION

To obtain the best performance from the machine and ensure the longest possible life of all its components, you must carefully follow the instructions for use and maintenance detailed in this manual. In the interest of our customers, we suggest any maintenance or repair of the equipment has to be made by qualified personnel.

All our products are subject to constant development. Therefore, we are compelled to reserve the right to make any necessary or useful changes in design and equipment.

ORDINARY MAINTENANCE

Exposure to extremely dusty, damp, or corrosive air is damaging to the welding machine.

Avoid any deposit of metallic dust inside the generator.

Disconnect the generator from the net before operating any servicing! Standard checks to the generator:

• Operate an internal cleaning by using low pressure compressed air and soft bristle brushes.
• Check the electrical connections and all the rest of the connecting cables. For the maintenance and the use of gas regulators consult the specific handbook.

Please note that: lack of maintenance can spell to the unavailability and cancellation of the guarantee.

POSSIBLE APPLICATION

Power sources type PLUS are suited for MIG / MAG applications with pulsation and synergy, FCAW cored wire, MMA and TIG Liftarc with a range up to 210A.

• It is forbidden to use the equipment for different applications from the ones listed in this manual. A different use from the one hereafter described can compromise the security of work and the reliability of the equipment.

We suggest not to use the Inverter Power Source PLUS 210 C (standard version):

• In environments with a high concentration of humidity and dust.
• With Input cables longer than 50 m.

Contact the service centre for advice and precautions, in case the unit must be installed and used under the above-listed conditions.

It is suggested to make a maintenance cleaning of the unit every 2-3 months of work, for this operation, please contact the service centre.

GENERAL PRECAUTIONS

If not opportunely carried out, welding represents a risk for the safety of the operator and of all the people which are within the immediate vicinities. It is recommended, therefore, to observe some fundamental safety rules such as:

• Limit the exposed area to smoke and radiation coming from the welding area by using special welding light screens (ANTIREFLEX) or, if possible, reserve a proper room for these industrial processes.
• Protect the body, in all its parts, with protective clothing and accessories (masks, helmets, etc...) and if possible, clothing needs to be adherent to the operator's body; use shoes with rubber soles in order to be opportunely isolated.
• Limit the fumes and gas formation by using clean, not rusted and not treated metal pieces; contrary, if it is not possible to operate as above, it is recommended the use of masks in order to favour the operator's breathing. Vacuums and ventilation systems should be built in order to grant a continuous air flow.

Positioning of the implant

To correctly position the system, follow these simple rules:

• Ensure easy access to controls and work equipment.
• Do not place the system in a confined space.
• Do not place the system on a surface with an inclination greater than 10° from the horizontal plane.

Warnings on the use of GAS cylinders

Inert gas cylinders contain pressurized gas and may explode if the minimum transport and storage conditions are not ensured.

• Always tighten the valve protection cover during transport, commissioning and whenever welding operations are completed.
• To avoid accidental mechanical drops or shocks, always fix the cylinders vertically to walls or other support with suitable means, chains, belts, etc.
• Do not expose the cylinders directly to sunlight and high-temperature changes. Do not expose the cylinders to too cold or too high temperatures.
• The cylinders must not come into contact with open flames, electric arcs, torches and electrode holders and the incandescent projections produced by welding.
• Keep cylinders away from welding circuits and current circuits in general.
• Keep the head away from the point where the gas leaks when the cylinder valve is opened.
• Always close the cylinder valve when the welding operations are finished.
• Never perform welding on a pressurized gas cylinder.

ELECTRICAL EMERGENCY NORMS

• Avoid working with cables that are in any way deteriorated, and make sure to correctly connect the AC phases and earth on a certified plug.
• Never wrap ground and/or torch cables around the operator's body.
• Avoid operating in humid or wet places without the proper precautions.
• Avoid operating if the machine protective panels (sides and cover) have been removed in order to grant the safety of both the operator and the system.

ANTIFIRE EMERGENCY NORMS

• Equip the workspace with proper fire extinguishers and periodically check the efficiency.
• Position the generator on a solid and horizontal surface making sure of the presence of good aeration. Do not obstruct the front and rear panel; this will let the machine overheat.
• Follow all the regulations applicable when welding has to be carried out on containers of lubricants or flammable substances.

Table 4: SUBMENU parameters
(- - -) = parameter not available in this machine

Below is the detailed description of the parameters of Table 4.

P01 - Burn Back Time (BBT)
Adjust the BBT value so that the length of the wire exiting the socket does not stick to the workpiece or to the torch.
A high value tends to make the wire stick to the contact tip, a low value tends to make the wire stick to the workpiece.

P02 - Wire approach speed
It is the wire speed when the machine is in no load. Once the arc is ignited, the speed automatically goes to the set one.

When the initial feed rate is too high, the wire will tap several times before igniting a stable arc; if the feed speed is too slow, the initial arc will be too long, and the wire could melt into the wire guide.

P03 - Pre-gas time
Time too long will cause a waste of time and gas. Time too short may cause triggering craters.

P04 - Post-gas time
Time too long will cause waste of time and gas; time too short may cause craters during the filling period of the crater.

P05 - Initial period value (in 4-Times Special mode)
Set the variation in percentage between the initial parameters and the welding parameters.

P06 - Final period value (in 4-Times Special mode)
Set the variation in percentage between the final period parameters and the welding parameters to properly fill craters.

P07 - Transition period value (in 4-Times Special mode)
During the special 4 times mode, set the transition time between the parameters. This will eliminate the sharp variation between the three parameters.

P11 - Double pulse frequency
Double Pulsation Welding is obtained by modulating, at low frequency, the synergy between two values called High Pulse and Low Pulse.
It is possible to adjust this frequency from OFF, single level of pulse, to dual-pulsed between 0.5 and 5.0 Hz.

Compared to single pulsed welding, double pulsed offers numerous advantages. The first is that, without manually oscillating, the weld will automatically take the shape of a "herringbone". Second, the depth and density of the welding seam will be adjustable with more precision, and you will obtain optimal control of the heat input. Finally, you will get a colder weld pool with lesser deformation of the workpiece at low currents.

Waveform of the Double pulsation

FIg.10

In Fig. 10 "T" indicates the double pulse frequency (P11), "T1" the high pulse value and "T2" the low pulse value.

P12 - Arc length correction of the high pulse group (in double pulsation)
To adjust the width of the "herringbone" bead.
Set high values for a wider bead and low values for a narrower bead.

P13 - Double pulse speed offset (in double pulsation)
To adjust the depth of the bead. Higher values correspond to greater depth of the "herringbone" bead.

P14 - High Pulse Group Ratio (in double pulsation)
Set high value for greater proportion of the entire projection and groove of the "herringbone" bead.

P17 - Initial current time (in 4-Times Special mode)
It is the time in which the initial current P05 remains, after this time the current will reach the set value. With the OFF setting this function is not active.

P18 - Final current time (in 4-Times Special mode)
It is the time in which the final crater filling current P06 remains, after this time the current will go to 0. With the OFF setting this function is not active.

P19 - Standard mode selection (not synergic)
OFF = synergic mode;
ON = standard mode, in this mode the two knobs (20) and (21) allow you to adjust the CURRENT and VOLTAGE values independently (no longer synergistic).

H01, H02 - HOT START (only in MMA mode) This function provides the following benefits:

• Improves the ignition, even when using electrodes with poor ignition properties
• Improve the fusion of the base metal in the start-up, which means fewer defects at the cold start of welding.
• Prevents most of slag inclusions.

Refer to the figure on the side. During the HOT START time, indicated with "H02", the welding current can be increased. This value, "H01", can be adjusted from 1 to 100% more than the current of welding set.

In the example in the figure, the set current is 100A. By setting a current of HOT START (H01) of 50%, and a time (H02) of 0.5 s, an initial current of 100A + (50% of 100A) = 150A for 0.5 s.

H03 - ANTI-STICKING (only in MMA mode)
With this function set to ON, the output current goes to about 15A when the electrode shortcircuits with the workpiece. This allows you to avoid damaging the electrode being used and to be able to detach from the piece without difficulty.

SPOOL GUN SOCKET

The connection diagram of the SPOOL GUN torch socket (optional) is shown below. Refer to figures 1, 3, 8. Note: before connecting, check if the selector (12) in the spool holder compartment is in the "SPOOL GUN" position.

If an error code other than those listed should appear, contact the service centre. Communicate the error code and serial number of the machine.

RESTORE FACTORY DATA

You can restore all the factory data by proceeding as follows. In this case, you will lose all settings.
	Turn on the machine. Press the KNOB (19) for at least 5 s. All data and settings will be reset to factory defaults.

CAUTION

Check whether:

• The power source is connected with earth cable
• All the connections are available. Particular attention should be drawn to the connection between the earth clamp and workpiece
• The output terminal of electrode holder and earth cable is not short-circuited;
• The polarity of output terminals is correct

Working Environment

1. Welding should be carried out in a relatively dry environment with a humidity of 90% or less.
2. The temperature of the working environment should be within -10C to 40C.
3. Avoid welding in the open air unless sheltered from sunlight and rain, and never let rain or water go into the machine.
4. Avoid welding in a dusty area or environment with corrosive chemical gas.
5. Avoid gas shielded arc welding in an environment with strong airflow.

Good Ventilation

This welding machine has such a great welding current when working that natural ventilation may not meet the cooling demand, while the inner fan enables the machine to work steadily by its effective cooling. Operator should make sure the louvres are uncovered and unblocked. The minimum distance between the machine and nearby objects should be 30cm. Good ventilation is of critical importance to the typical performance and service life of the machine.

Over-voltage is forbidden

The power supply voltage has been shown in the main parameter table. Generally speaking, the voltage in the welding machine will automatically compensate the circuit to ensure the welding current is in the acceptable range. If the voltage exceeds the acceptable limit, you will damage the device. The users should understand this situation and take the corresponding measures. So, pay attention to voltages changes. Once overvoltage occurs, stop welding and switch off the power.

Over-load is forbidden

The users should check the max permitted load current at any time (relatively the fixed duty cycle). The welding current cannot exceed the max allowed load current. Overloading the current will cut the welding machine use life remarkably and maybe burn the welding machine.

Over-heating Protection

Over-heating protection appears while the machine is overloaded because of continuous welding for a long time, and a sudden halt of welding occurs. In this case, it is unnecessary to restart the machine but just wait for the over-heating LED to go out, and welding can be recovered.
