Installation and Operator Instructions

Technical description

Description
The system consists of a modern direct current generator for the welding of metals, developed via application of the inverter. This special technology allows for the construction of compact light weight generators with high performance. Lt’s adjust ability, efficiency and energy consumption make it an excellent work tool suitable for coated electrode and GTAW (TIG) welding).

Technical data
The machine can be connected to a motor generator of power meeting the data plate specifications and having the following characteristics:

Output voltage between 185 and 275 Vac.
Frequency between 50 and 60 Hz.

IMPORTANT: MAKE SURE THE POWER SOURCE MEETS THE ABOVE REQUISITES. EXCEEDING THE SPECIFIED VOLTAGE CAN DAMAGE THE WELDING MACHINE AND INVALIDATE THE WARRANTY.

Duty cycle and overheating
Duty cycle is the percentage of 10 minutes at 40°C ambient temperature that the unit can weld at its rated output without overheating. If the unit overheats, the output stops and the over temperature light comes On. To correct the situation, wait fifteen minutes for unit to cool.
Reduce amperage, voltage or duty cycle before starting to weld again (See page III).

Volt – ampere curves
Volt-ampere curves show the maximum voltage and amperage output capabilities of the welding power source.
Curves of other settings fall under curves shown (See page III).

Installation
Important: before connecting, preparing or using equipment, read safety precautions.

Connecting the power source to the mains electricity supply
SERIOUS DAMAGE TO THE EQUIPMENT MAY RESULT IF THE POWER SOURCE IS SWITCHED OFF DURING WELDING OPERATIONS.
Check that the power socket is equipped with the fuse indicated in the features label on the power source. All power source models are designed to compensate power supply variations. For variations of + 15% a welding current variaton of +- 0,2% is created.

BEFORE INSERTING THE MAINS PLUG, IN ORDER TO AVOID THE FAIL OF POWER SOURCE, CHECK IF THE MAINS CORRESPONDS TO THE WISHED MAIN SUPPLY.

On – off switch: This switch has two positions:
ON = I and OFF = O.

THIS CLASS A EQUIPMENT IS NOT INTENDED FOR USE IN RESIDENTIAL LOCATIONS WHERE THE ELECTRICAL POWER IS PROVIDED BY THE PUBLIC LOW-VOLTAGE SUPPLY SYSTEM. THERE MAY BE POTENTIAL DIFFICULTIES IN ENSURING ELECTROMAGNETIC COMPATIBILITY IN THOSE LOCATIONS, DUE TO CONDUCTED AS WELL AS RADIATED DISTURBANCES.

Connection and preparation of equipment for stick welding
TURN OFF WELDER BEFORE MAKING CONNECTIONS.
Connect all welding accessories securely to prevent power loss. Carefully follow safety precautions described.

Fit the selected electrode to the electrode clamp.
Connect the ground cable quick connection to the negative (-) receptacle and locate the clamp near the welding zone.

Process selector
(Rif.1 – Picture 1.). In this position welding can be used with rutile, basic electrodes, and specially coated electrodes.

Lift TIG procedure
In this position the TIG welding process with lift mode ignition can be selected, as described previously.

To ignite the arc
TIG welding, proceed as follows:

Touch the welding piece with the electrode; this will cause a short circuit between the piece (2) and the electrode (1).
Lift off the electrode; the arc will ignite.

The integrity of the electrode tip is guaranteed by the low ignition current during short-circuiting between the welding piece and the electrode ignition is guaranteed even at minimum welding current settings; the operator can therefore work without contaminating the ambient with electromagnetic disturbance, normally caused by high frequency discharges.

The advantages can be this summarized:

no need for high-frequency startups,
no damage to the electrode tip during start-ups, regardless of ampere setting, thereby avoiding the presence of tungsten in the welding piece, common during scratch starting.

Fault led (Yellow)
(Rif.2 – Picture 1.). When the fault led lights on, the overheating occurs inside the unit due to the exceeding the rated duty cycle. Happening that the welding operations have to be stopped, the welding power source has to be kept on until the led lights off so the unit is ready to weld again.

Current regulation
(Rif.3 – Picture 1.). This potentiometer adjust the welding current range.

On – off switch
(Rif. 4 – Picture 2.). This switch has two positions: ON = I and OFF = O.

Arc led illuminated (Green)
(Rif.5 – Picture 1.). This led lights when the machine is turn on.

NOTE
The power source is fitted with an anti-sticking device that disables power if output short circuiting occurs or if the electrode sticks, allowing it to be easily detached from the work piece. This device enters into operation when power is supplied to the generator, even during the initial checking period, therefore any load input or short circuit that occurs during this phase is treated as a fault and will cause the output power to be disabled.

Troubleshooting procedure

Types of malfunctioning / welding faults – causes – remedies.

TYPES OF MALFUNCTIONING WELDING FAULTS| POSSIBLE CAUSES| CONTROLS AND REMEDIES
---|---|---
The generator does not weld: the digital switch is not lit.| The main switch is off.
The power lead is interrupted (lack of
one or two phases). Other.| Switch on mains. Verify and repair.
Ask for the intervention of the Assistance Centre.
During welding suddenly the outgoing current is interrupted, the orange led goes on.| Overheating has occurred and the automatic protection has come on. (See work cycles).| Keep generator switched on and wait till temperature has dropped again (10-15 minutes) to the point where the orange

switch goes off again.

Welding power reduced.| Outgoing wires are not correctly attached. A phase is missing.| Check that wires are intact, that the pliers are sufficient and that they are applied to welding surface clean from rust, paint or oils.
