WELDING PROCESS: DESCRIPTION OF

CONTROLS AND SIGNALS

Once you have put the welding machine into operation,

switch it on and apply the required adjustments.

Adjusting the welding current

Select the welding current depending on the electrode type, joint and

welding position.

Indicatively, the different currents to be used with the different

electrode diameters, are listed in Fig. 4.

To strike the welding arc with the coated electrode, brush it onto the

piece to be welded and, as soon as the arc is struck, constantly hold

it at a distance equal to the electrode diameter and at an angle of

approximately 20º – 30º in the direction in which you are welding.

To strike the welding arc with the TIG torch, make sure the protection

gas valve is open. With a rapid, confident move, touch and then take

away the electrode point from the piece to be welded.

Heating stop indication

If the warning light is switched on (or see "HEA" in the display),

means that the thermal protection is already on.

If the duty cycle "X" shown on the data plate is exceeded, a thermal

cutout stops the machine before any damage is caused. Wait for the

operation to be restored and, if possible, wait for a few minutes more

until the gear factor is complied.

If the thermal protection is continuously on, means that the machine

is overworking.

"Hot start"

The welding machine is fitted with an automatic device that

facilitates the striking of the arc, increasing the current only at that

very moment.

"Antisticking"

The welding machine is fitted with an automatic device that interrupts

the current for a few seconds after having detected that the electrode

has tuck to the piece to be welded. By doing so, the electrode will

not overheat.

RECOMMENDATIONS FOR USE

- Only use an electrical extension cord when absolutely necessary,

and providing it has an equal or larger section to the power cable and

is fitted with a grounding conductor.

- Do not block the welder air intakes. Do not store the welder in

containers or on shelving that does not guarantee a suitable

ventilation.

- Do not use the welder in any environment where in presence of

gas, vapors, conductive powders (e.g: iron shavings), brackish air,

caustic fumes or other agents that could damage the metal parts and

the electrical insulation.

The electric parts of the welder have been treated with protective

resins. When used for the first time, smoke may be noticed; this is

caused by the resin drying out completely.

The smoke should only last for a few minutes.

MAINTENANCE

Switch off the welder and remove the plug from the power socket

before carrying out any maintenance operation.

Extraordinary maintenance of the machine must be periodically

carried out by expert staff or qualified electrical mechanics,

depending on the use.

- Inspect the inside of the welder and remove any deposited dust on

the electrical parts (by using compressed air), and in the electronic

cards (using a very soft brush and appropriate cleaning products).

- Check that the electrical connections are tight and the insulation on

the wiring is not damaged.
