SAFETY AND PROTECTION

Please read the safety instructions carefully before starting the equipment and starting the welding work. SOLTER welding equipment should only be operated by personnel trained and instructed in the use of welding equipment, and who are familiar with the safety regulations.
ELECTRICITY
The good operation of the machine is ensured by a good installation. Check that the voltage (V) of the machine corresponds to the mains voltage. The earth connection (yellow / green wire) should ALWAYS be connected. Never touch live metal parts with bare skin or wet clothing.
Check that your clothes, equipment and surroundings are always dry.
Do not use worn or damaged welding cables. Do not overload the welding cables. Use only good material.
Do not wind the cable in the form of loops or on the equipment case.
Unplug the equipment if you do not use it for long periods.
Do not leave the welding equipment unsupervised.
People with implanted electrical elements (PACEMAKERS) must not use devices of this nature.
PERSONAL CLOTHING
The entire body of the welder is subject to the possible action of aggressive agents, so it must be fully protected. Wear safety boots, gloves, muffs, leggings and leather aprons.
AGAINST BURNS
Never touch parts of the wire or material with bare hands after soldering. Prevent the detached particles from coming into contact with the skin. Do not point the torch at any part of the body.
EYE PROTECTION
Welders and their assistants must use safety glasses fitted with filters that stop radiation harmful to the human eye. Using special screens it is possible to observe the welding area during the process.
FIRE PROTECTION
The welding process causes incandescent metal projections that can cause fires. Do not use the machine in environments with flammable gases. Clean the work area of all combustible material. Especially protect gas bottles according to the requirements they require.
PROTECTION OF GAS CYLINDERS
Cylinders containing shielding gases store them at high pressures. If they suffer some type of breakdown, they may explode. Always treat cylinders with care and weld as far as possible from them. The bottle should be attached to the wall or equipment properly, to avoid risks.
Avoid:
– Direct exposure to the sun.
– Very high temperatures.
– Calls.
WHEN PROCEEDING TO WELD DEPOSITS WITH REMAINS OF FLAMMABLE MATERIALS THERE IS A GREAT RISK OF EXPLOSION. IT IS RECOMMENDED TO HAVE A FIRE EXTINGUISHER READY FOR USE.
ELECTROMAGNETIC DISTURBANCES

WELDING PROCEDURE THROUGH COATED ELECTRODES

• Electric arc welding with coated electrodes is a procedure by which the union between two metal parts is made taking advantage of the heat generated by an electric arc that is produced between the fusible electrode and the material to be welded .
• Welding machines can be direct current or alternating current; the former can weld any type of electrode, while the latter can weld only electrodes intended for alternating current.
• The constructive characteristic of these machines is such as to guarantee a good degree of stability of the arc in terms of variations in its length due to the approach or removal of the electrode caused by the welder’s hand.
• The electrode is made up of two fundamental parts:
  a) The core, which is of the same nature as the base material (aluminum, iron, copper, steel, stainless) and fulfills the function of contributing material to the joint.
  b) The coating, made up of various mineral and organic substances mixed together, whose functions are:
  Gaseous protection. A part of the cladding, volatilized at arc temperature, removes air from the area creating a column of ionized gas that protects the molten material.
  Contribution of binding and slagging elements. A part of the lining melts and contributes some elements to the fusion bath that combine with the material of the core.
  The main types of coating are:
  Rutile coatings. These coatings give the cord a very good aesthetic appearance, which is why it is widely used.
  It can be welded in both alternating current and direct current with both polarities.
  Basic coatings. They are essentially used for welds of good mechanical quality, although the arc tends to splash and the aesthetics of the bead is inferior to that of rutile coating. They are generally used in direct current with the electrode at the positive pole (reverse polarity), although there are some basic electrodes for alternating current. Basic coatings are sensitive to humidity, therefore they must be stored in a dry environment, in well-closed boxes. We also remember that steels with a carbon content greater than 0.6 need
  to be welded with special electrodes.
  Acid coatings. These coatings give good weldability and can be used in alternating current or in direct current with clamp-electrode holder to the negative pole (direct polarity). The fusion bath is very fluid for that reason the electrodes are essentially suitable for flat welding.

ELECTRODE CHOICE
The choice of electrode diameter depends on the thickness of the material, the type of joint and the position of the weld. When executing “positive” welds, the bath tends to fall due to the force of gravity, therefore it is advisable to use a small diameter electrode in successive passes. For thick diameter electrodes, high welding currents are required that provide adequate thermal energy.
CHOICE OF WELDING CURRENT
The stability and continuity of the weld allow working with currents of low values and in conditions of particular difficulty. The following table indicates indicatively the minimum and maximum usable current for welding on carbon steel.

ELECTRODE DIAMETER| WELDING CURRENT|
---|---|---
mm| Minimum| Maximum
1.6|  25 A|  50 A
2|  40 A|  70 A
2.5|  60 A|  110 A
3.25|  100 A|  140 A
4|  140 A|  180 A
5|  180 A|  200 A

TIG WELDING PROCEDURE
Gas Tungsten Arc Welding (GTAW) is the definition of the welding procedure in which the arc, during work, is maintained by means of an electrode metallic infusible (commonly tungsten). The arc zone (electrode and fusion bath) is protected against atmospheric contamination by means of an inert gas such as argon or helium that flows continuously through appropriate ducts in connection with the torch. For simplicity and uniformity, all reference to the procedure in this manual is expressed with the thermal TIG (Tungsten Inert Gas). This procedure can be used to carry out clean and exact welds on all kinds of metals, respecting their physical-chemical composition. Thanks to this feature, TIG welding represents the only suitable method to join certain metals.
Because of these characteristics inherent in the TIG process, the welding approach must meet very precise specifications. TIG welders are designed and built with these provisions. By being installed, used and maintained in the correct way they can provide a long and satisfactory service creating correct and clean welds.
The TIG torch connects directly to the output of the welding machine and manual gas control is induced in the torch. Priming is made easier by the characteristics of the generator.
Frequently the arc priming is obtained by means of a device called high frequency (HF) that generates high voltage impulses (kV), on the other hand, the friction output does not foresee “high frequency” but a momentary short circuit situation; at the moment the electrode is raised, the arc is established and the current is transferred to the previous value set.
TIG WELDING SCHEME (Fig. 3)

1. Respect the indications given above about the primary and the installation.
2. Connect the earth cable to the positive + socket of the welding machine.
3. Connect the torch to the negative socket – of the welding machine.
4. Connect the gas cylinder (argon) to the device in the TIG torch.
5. Proceed with the welding, adjusting the intensity using the potentiometer.

PROTECTION GAS TIG WELDING
The protection gas normally used is pure argon with a variable quantity depending on the current used (4-8 l / min). The TIG procedure is indicated for the welding of steels (both carbon and alloyed), it allows an optimal- looking weld, it is often used for the first pass on tubes. Before each weld it is necessary to carefully prepare and clean the edges.
CHOICE OF ELECTRODES FOR TIG WELDING
The electrodes normally used are tungsten with Thorium (red coloration). As a guide we give a table with the diameters and the corresponding intensities.

PREPARATION OF ELECTRODES FOR TIG WELDING
Particular attention is required in the preparation of the electrode tip, as indicated in the next drawing. The angle a varies with the welding current; the following table recommends its value:

DIGITAL MODELS DESCRIPTION

2. Indicator of anomalies.
3. Arc boost current (Ifor): MMA mode. This parameter configures the increase in peak current during welding to increase the welding power by shortening the arc. The adjustment values are 0% to 25% increase over I1.
4. Welding current (I1): In this parameter we will introduce the current in amps that the equipment must supply, this will depend on the electrode used. The adjustment limit is between 10A and 200A (depending on model).
5. Starting current (I-hot): MMA mode. Determines the arc starting current (Hot Start), improving the start of difficult electrodes. In this case the possible values are from 0% to 25% increase over I1. Once the% increase has been selected, the time during which the I-hot current will be applied can be selected.
