Glosario de Terminología usada por soldadores

CA o Corriente Alterna - corriente eléctrica que cambia de dirección periódicamente. Corriente de 60 ciclos se desplaza en ambas direcciones 60 veces por segundo.

Longitud del Arco - la distancia entre el extremo del electrodo y el punto de contacto con la superficie de trabajo. Metal Básico - el material que se va a soldar.

Unión a tope - la unión de dos miembros alineados aproximadamente en el mismo plano.

Cráter - el vacio que se forma cuando el arco hace contacto con el metal básico.

CD o Corriente Directa - corriente eléctrica que se deplaza en un sólo sentido. La polaridad (+ o -) determina el sentido del desplazamiento.

CD Polaridad Reversa - ocurre cuando el portaelectrodo está conectado al polo positivo de la soldadora. Esta tecnica dirije más calor para derretir el electrodo en vez de la pieza de trabajo. Generalmente esta técnica se usa con piezas delgadas.

CD Polaridad Directa - oocurre cuando el portaelectrodo está conectado al polo negativo de la soldadora. Con esta tecnica la mayoría del calor se dirije a la pieza de trabajo para lograr una mayor penetración en piezas gruesas.

Electrodo - un alambre de metal con una capa que tiene aproximadamente la misma composición del material que se va a soldar.

Soldadura de Filete - soldadura triangular, para unir dos superficies en ángulo recto, en T o en las esquinas. Fundente - un material, que al calentarse, emite un gas que cubre el área donde va a soldar. Este gas protege los metales que va a soldar contra las impurezas presentes en el aire.

Soldar con Arcos de Fundente - también se conoce como soldar sin gas, esta técnica para soldar usa una soldadora con alambre. El alambre es tubular y lleno de fundente.

Soldar con Arcos de Metal Gaseoso - es un proceso para soldar usado con una soldadora con alambre. El alambre es sólido y se usa un gas inerte.

Soldar con Arcos de Tungsteno - es un proceso para soldar usado con soldadoras con generadores de alta frecuencia. El arco se crea con un electrodo no-consumible de tugnsteno. No necesariamente se usa metal de relleno.

Unión de superposición - la unión de dos miembros superpuestos en planos paralelos.

Voltaje de circuito abierto - el voltaje entre el electrodo y la pinza de conexión a tierra de la soldadora cuando no hay flujo de corriente (no se está soldando). Esto determina la rápidez con que se enciende el arco.

Sobremonta - ocure si el amperaje es demasiado bajo. En este caso, el metal derretido se cae del electrodo sin haberse unido al metal básico.

Porosidad - cavidad que se forma durante la solidificación del área soldada. Las porosidades debilitan la unión. Penetración - la profundidad que el arco se penetra dentro de la pieza de trabajo durante el proceso de soldar. Para soldar bien se debe lograr 100% de penetración, es decir todo el grosor de la pieza de trabajo se debe derretir y solidificar. El área afectada por el calor se debe ver facilmente desde el otro lado.

Soldar con arcos protegidos - es un proceso de soldar que usa un electrodo consumible para sostener el arco. La protección se logra al derretir el fundente del electrodo .

Escoria - una capa de residuo de fundente que protege la unión de óxidos y otros contaminantes mientras los metales se solidifican (enfrian). Esta se debe limpiar una vez que el metal se haya enfriado. Salpiqueo - las particulas de metal que salpican durante el proceso de soldar y que se solidifican en la superficie de trabajo. Esto se puede minimizar al rociar un repelente adecuado antes de comenzar a soldar.

Soldadura de puntos - una unión hecha para mantener las piezas alineadas hasta que se haya completado el proceso de soldar.

Angulo de desplazamiento - el ángulo del electrodo con respecto a la línea a soldar. Este varia entre los 5º y 45º según sean las condiciones.

Unión en T - es la unión del borde de una pieza de metal con la superficie de otra en un ángulo de 90º .

Socavación - el resultado de soldar con un amperaje demasiado alto. Esto ocasiona ranuras en ambos lados de la reborde que reduce la resistencia de la unión. Sedimento - el volumen de metal derretido al soldar antes de que se solidifique como metal soldado.

Reborde - una capa delgada o capas de metal depositado en el metal básico cuando el electrodo se derrite. Generalmente su grosor es el doble del diámetro del electrodo.

Angulo de trabajo- el ángulo del electrodo con respecto a la línea horizontal, medido en ángulos rectos a la línea de soldar .

Installation

LOCATION

Selecting the proper location can significantly increase performance, reliability and life of the arc welder.

For best results locate the welder in an environment that is clean and dry. Avoid locations exposed to high temperature, high humidity, dust and corrosive fumes. High humidity causes moisture condensation on electrical components. Moisture can contribute to corrosion and short electrical components. Dust and dirt in the welder retain moisture and increase wear of moving parts.

Place the welder in an area that provides at least twelve inches (305 mm.) of ventilation space at both the front and rear of the unit. Keep all obstructions away from this ventilation space.

Store electrodes in a clean, dry location with low humidity, such as WT2240 Electrode Container, to preserve the flux coating.

The welder control panel contains information regarding proper input voltage and amperage. Follow the specifications on the welder front panel.

The receptacle used for the welder must be properly grounded and the welder must be the only load on the power supply circuit. Refer to the Circuit Amps chart under Specifications for correct circuit capacity.

The use of an extension cord is not recommended for electric arc welding machines. The voltage drop in the extension cord may significantly degrade the performance of the welder.

Operation

1.Be sure to read, understand, and comply with all precautions in the General Safety Information section. Be sure to read the entire section entitled Welding Guidelines prior to using this equipment.

2.Turn welder off and plug into appropriate receptacle: 230v-50 amp

3.Verify that the surfaces of metals to be joined are free from dirt, rust, paint, oil, scale or other contaminants. These contaminants make welding difficult and cause poor welds.

All persons

! WARNING operating this equipment or in the area while equipment is in use must wear protective welding gear including: eye protection with proper shade, flame resistant clothing, leather welding gloves, and full foot protection.

If heating,

! WARNING welding, or cutting materials that are galvanized, zinc plated, lead, or cadmium plated refer to the General Safety Information Section for instructions. Extremely toxic fumes are created when these metals are heated.

4.Connect the ground clamp to the work piece or workbench (if metal). Make sure the contact is secure, and not obstructed by paint, varnish, corrosion, or non-metallic materials.

5.Insert the exposed part of the electrode (the end with no flux) into the jaws of the electrode holder.

6.Set the amperage adjustment knob to the proper amperage for the electrode diameter. Refer to the following chart for proper electrode current settings.

The electrode

! WARNING holder and rod are electrically "hot"(have current potential) when the welder is on. Grounding against any metallic surface may produce an arc which could cause sparks and damage eyesight.

7.Hold the electrode and holder away from the grounded work piece or workbench. Turn on the welder. A green light is illuminated when the welder power is on.

8.Position the electrode to begin weld, lower the welding helmet or position the hand shield, and strike an arc. Adjust weld amperage as needed.

9.When finished welding, turn welder off and store properly.

Duty Cycle / Thermostatic

Protection

Welder duty cycle is the percentage of actual weld time that can occur in a ten minute interval. For example, at a 10% duty cycle, actual welding can occur for one minute, then the welder must cool for nine minutes.

Internal components of this welder are protected from overheating with an automatic thermal switch. A yellow lamp is illuminated on the control panel

if the duty cycle is exceeded. Welding operations may continue when the yellow lamp is no longer illuminated.

Maintenance

Disconnect power ! WARNING supply and turn

machine off before inspecting or servicing any components.

Before every use:

1.Check condition of weld cables and immediately repair or replace any cables with damaged insulation.

2.Check condition of power cord and immediately repair or replace any cord if damaged.

3.Check condition of electrode holder insulating pieces and immediately replace cracked or missing insulators. Verify that all fasteners are tight and insulated.

Do not operate this ! WARNING welding machine

with cracked or missing insulation on welding cables, electrode holder, or power cord.

Every 3 months:

Replace any unreadable labels on the welder. Use compressed air to blow all dust and lint from the ventilation openings.

Welding Guidelines

General

This line of welding machines utilizes a process known as Shielded Metal-Arc Welding (SMAW). This process is used to bond metals by heating them with an electric arc created between the electrode and the work piece.

Electrodes used for shielded metal arc welding have two parts. The inner core is a metal rod or wire that should be similar in composition to the base metal. The outer coating is called flux. Various types of flux exist. Each coating is used for a particular welding situation.

While the metal is molten, it can be contaminated by elements in the air. This contamination could weaken the weld. The flux coating creates a protective barrier called slag that protects the molten metal from contaminants.

Operating Instructions and Parts Manual

Shielded Metal Arc Welder

When current (amperage) flows through the circuit to the electrode, an arc is formed between the end of the electrode and the work piece. The arc melts the electrode and the work piece. The melted metal of the electrode flows into the molten crater and forms a bond with the work piece as shown.

Note: Discontinue using and discard electrodes that burn down to 1 to 2 inches from the electrode holder.

Striking an Arc

Place the bare end of the electrode in the holder. Grip the holder lightly to reduce tiring of the hand and arm.

Note: Always keep the jaws of the holder clean to insure good electrical contact with the electrode.

Be careful not to ! WARNING touch the work

piece or welding bench with the electrode as this causes arc flashes.

There are two methods which can be used to start or strike the arc; the tapping method and the scratching method. In the tapping method, the

electrode is brought straight down and tapped on the work piece.

With the scratching method, drag the electrode at an angle along the surface much like striking a match. Regardless of method, upon contact with the plate, immediately raise the electrode a distance equal to the diameter of the electrode or it will stick to the surface. Always hold the electrode pointed into the weld.

Note: Should the electrode stick to the work piece, break it loose by quickly twisting or bending at the holder while pulling upward. If the electrode does not break loose, disengage the electrode by releasing it from the holder.

Arc Welding Basics

Five basic techniques affect weld quality. These are: electrode selection, current setting, weld angle, arc length, and travel speed. Proper implementation of these techniques is necessary for good weld quality.

Electrode Type and Size

The correct choice of electrode type involves a variety of factors, such as welding position, work piece material type, thickness, and condition of surface to be welded. The American Welding Society, AWS, has set up certain requirements for each type of electrode.

All electrodes are classified into five main groups: mild steel, high-carbon steel, special alloy steel, cast iron, and nonferrous such as aluminum. The

Flux type

majority of arc welding is done with the electrodes in the mild steel group. The electrode material should correspond with the work piece material.

Flux coatings are made for use with either AC (alternating current), DC (direct current) reverse polarity, or DC straight polarity, although some function well on both AC and DC current.

Commonly Used Electrodes

1. E-6011 Deep Penetrating

The strong arc force and rapid solidification of the metal makes vertical and overhead welding easier with this rod.

Where time does not permit rust, scale or paint removal, this rod penetrates rapidly and easily.

Acceptable for AC or DC welding current (reverse polarity).

2. E-6013 General Purpose

All position, smooth deposit rod with low spatter.

For all mild steel and general purpose work.

Acceptable for AC or DC welding current (straight or reverse polarity).

3. E-7014 Iron Powder

A general purpose "drag" rod for all positions.

Ideal for situations where fit between metal pieces is poor.

The iron powder in the flux coating combines with the filler rod to make a smooth deposit with very little spatter.

Ideal for ornamental work.

Acceptable for AC or DC welding current (reverse polarity).

4. E-7018 Low Hydrogen

An all position high strength electrode designed to produce low hydrogen content combined with excellent mechanical properties.

Acceptable for AC or DC welding current (reverse polarity).
