POWER LINE CONTROL DEVICE (PLC)

The machine comes with a patented electronic circuit called a “PLC.” The ON-OFF switch is positioned on the front panel of the machine. The domestic (household) current is normally limited to 16A. If using the machine in a domestic environment position the switch on 16A.

ATTENTION: If the machine is used mainly in an industrial environment, we recommended using a ≥16A

industrial plug. In this case, the PLC device should be positioned on 25A (industrial applications). Use power plugs above 16A for industrial applications.

OPERATION OF THE PLC DEVICE The series of PRIMA MULTI 204 machines are based on a professional generator for medium/light applications. The duty-cycle factors are rather extreme and the architecture of the inverter allows welding at high currents. When the machine is connected to a domestic (household) mains power supply, a 16A plug must be fitted on the power supply cord. The overall current requested must be below 16A in order to prevent the automatic disconnection of the system. For this purpose, the PLC device controls the current absorbed by the machine and automatically stops the welding process when the current levels absorbed reach 16A. The performance of the machine is not reduced, only the welding cycle is restricted when the requested current exceeds the limits available. The graph below shows the welding time (cycle) in relation to the type of current available – industrial (red) or domestic (green) – for a MIG welding process.

PLC CURVE Based on what was previously said, the graph to the side shows the duty-cycle factors. The red lines refer to industrial currents while the green lines to domestic currents, which as mentioned are limited to 16A. In this last case, the PLC device must be set on 16A.

PLC - PANEL When the PLC device enters into operation, the machine stops functioning and the front display indicates the time necessary for its reset (countdown). The welding process can resume once the timer reaches “0”. Refer to the curves (graphs) indicated in order to prevent unexpected interruptions when welding in a domestic environment.



STANDBY

When not used continuously the machine enters into “STANDBY” in order to reduce consumption to 10 W. The “STANDBY” LED will light up. The cooling fan enters into function only when required. When welding at low current, it will enter into function at irregular intervals.

MOTOR GENERATOR – CONTROL OF CURRENT PEAKS The standard machine is also set up to operate with motor generators and/or long power supply cords, within the voltage limits of 180 V and 270 V. When the voltage exceeds these limits, the machine stops functioning and the front display will indicate the current peak, as shown in the figure. Reset the machine by turning it off and on.

Display: indicates the voltage peak value

Display: correct electric supply



GAS CONNECTION The generator is fitted with two gas connection tubes: one tube relates to the ARGON gas cylinder for welding aluminium alloys and CU-Si alloys, normally connected to outlets 1 and 2; and the other tube relates to the ARGON-CO2 MIX (mixture of 82% Ar and 18% CO2) gas cylinder for welding on mild steel with SG2 wire, normally connected to outlet 3. Other types of gas and materials can be used, such as for example, the mixture recommended for welding stainless steel is 98% ARGON and 2% CO2. In this case, it is recommended to use outlet 3 and to position the program on outlet 3 for welding stainless steel. Connect the pressure reducer on the cylinders, then connect the gas tubes, open the cylinders and adjust the gas output at around 14 litres/minutes for each outlet.

ATTENTION: Make sure the cylinders are well secured to the cylinder support before proceeding with the welding process.

LOADING OF WIRE COILS The machine is set up to use wire coils with a diameter of 200 mm. The welding machine can weld any type of material on any of the torch outlets. In order to simplify its use in the car-refinishing sector, we recommend adopting the following wire sequence. Outlet “1” for welding aluminium alloys with Ø 1 mm aluminium wire. Outlet “2” for braze welding carbon steel with Cu-Si3, Ø 0.8-1.0 mm wire. Outlet “3” for welding carbon steel with SG2, Ø 0.6-0.8-1.0 mm wire.

For each of the wire feed units: a) make sure the wire feed rollers are positioned according to the diameter of the wire used; b) position the coil, insert the wire between the rollers and in the Euro connection, and then secure the rollers

properly; c) connect the MIG/MAG torch; d) press the torch button, the wire will exit slowly for the first five seconds and then stop. At this point, “INC 10” will

appear on the display. Quickly release and press the button again, the wire will start feeding again at a speed of around 10 m/min. The wire is fed only when the button is pressed. In this phase, the supply of gas is blocked to prevent useless waste.



OPERATION DESCRIPTION

Multi 204 Torch connection panel

The PRIMA MULTI 200 welding machine is set up to weld on 5 independent torch outlets.

ATTENTION: THE RELATIVE PROGRAMS WITH THE ADJUSTMENTS MEMORISED CAN ALSO BE RETRIEVED VIA THE WELDING BUTTONS POSITIONED ON EACH TORCH. THE ADJUSTMENTS ARE MEMORISED AT EACH WELDING PROCEDURE, AND REMAIN THE SAME FOR THE SUBSEQUENT WELDING PROCEDURE, EVEN AFTER ANOTHER TORCH HAS BEEN USED OR AFTER THE WELDING MACHINE HAS BEEN TURNED OFF.

IMPORTANT BEFORE STARTING ANY TYPE OF WELDING PROCESS, PRESS THE

BUTTON OF THE TORCH YOU WANT TO USE. THE MACHINE RECOGNISES

THE TORCH AND PLACES ITSELF ON THE APPROPRIATE PROGRAM. THE

PARAMETERS CAN BE SET AND/OR CHANGED BEFORE WELDING.

ATTENTION:



The thickness of the base materials is calculated according to a normal horizontal welding procedure. In case of joints or different positions, increase or reduce the current/thickness values.

ADJUSTMENT OF THE ARC LENGTH

The arc length has thermal effects on the welding to be executed, and therefore, depends on the thickness of the piece to be welded. Effects of the arc length on the welding process.

LONG ARC (+):

The welding becomes flatter and the bead becomes wider, consequently the welding temperature increases.

SHORT ARC (-):

The welding becomes more concentrated and the bead becomes smaller, consequently the welding temperature decreases.

ADJUSTMENT OF THE INDUCTANCE

Effect of the adjustment of the inductance on the weld bead.

HIGH INDUCTANCE (+)

With a high inductance, the welding gets wider and the penetration decreases.

LOW INDUCTANCE (-)

With a low inductance, the welding gets smaller and the penetration increases.
