    ARC Welders

    These ARC Welders are widely used to melt by forming an electric arc, that makes it easy for the welder to reach the melting temperature of the metals fast. they are well known because they need a low capital and very minimal running costs. We manufacture ARC Welders using quality raw materials. Our construction has an electric arc between electrodes that allows the metal to melt at its desired melting point. Our ARC Welders are light in weight and are easily movable. They have both AC and DC current supply provisions. ARC Welders have sufficient circuit voltage, so is suitable for both AC and DC electrodes. Current regulation is very smooth, and there is no risk of interruption.

    In arc welding, the powerful heat needed to thaw metal is created by an electric arc. The arc is created amid the actual work and an electrode (stick or wire) that is physically or automatically guided along the joint. The electrode can either be a rod with the rationale of simply carrying the current between the tip and the work. Or, it may be a specifically prepared rod or cable that not only carry out the current but also melts and supplies filler metal to the joint. Most soldering in the creation of steel products uses the second type of electrode.

    Basic Welding Circuit:

    The basic arc-welding circuit is nothing but an AC or DC power source, fitted with whatsoever controls may be required, is coupled by a work cable to the work piece and by a "hot" cable to an electrode holder of some type, which creates an electrical contact with the soldering electrode.

    An arc is generated across the gap when the energized circuit and the electrode tip touches the work piece and is inhibited, however still with in close contact.

    The arc produces a heat of about 6500oF at the tip. This heat melts both the base metal and the electrode, producing a pool of molten metal sometimes called a "crater." The crater hardens after the electrode as it is moved along the joint. The end result is a fusion bond.

    Arc Shielding:

    Although, combining metals needs other than moving an electrode beside a joint. Metals at elevated temperature are likely to respond chemically with elements in the air - oxygen and nitrogen. When metal in the molten pool comes into contact with air, oxides and nitrides form which demolish the strength and sturdiness of the weld joint. Consequently, many arc-welding procedures offer some means of covering the arc and the molten pool with a defensive shield of gas, vapor, or slag. This is called arc shielding. This shielding avoids or lessens contact of the molten metal with air. Shielding also may recover the weld. An example is a granular flux, which actually adds deoxidizes to the weld.

    Shielding of the welding arc and molten pool with a Stick electrode. The extruded covering on the filler metal rod, provides a shielding gas the point of contact while the slag shields the brand new weld from the air. The arc itself is a very composite occurrence. In-depth understanding of the physics of the arc is of minute value to the welder, but some understanding of its general personality can be useful.

    Nature of the Arc:

    An arc is an electric current moving between two electrodes through an ionized column of gas. A negatively charged cathode and a positively charged anode create the strong heat of the welding arc. Negative and positive ions are rebounded from each other in the plasma column at a hastened rate.

    In welding, the arc not only offers the heat required to melt the electrode and the base metal, but under assured conditions must also deliver the means to transport the molten metal from the tip of the electrode to the work. Numerous mechanisms for metal transfer subsist. The examples include:
    1. Surface Tension Transfer - a drop of molten metal tapes the molten metal pool and is drained into it by surface tension.
    2. Spray Arc - the drop is expelled from the molten metal at the electrode tip by an electric pinch impelling it to the molten pool. It is grand for overhead welding.

    If an electrode is fragile, the tip melts under the heat of the arc and molten droplets are separated and transported to the work through the arc column. Any arc soldering system in which the electrode is melted off to become part of the solder is depicted as metal-arc. In carbon or tungsten (TIG) welding there are no molten droplets to be forced across the gap and onto the work. Filler metal is melted into the joint from a separate rod or wire. More of the heat created by the arc is relocated to the weld pool with consumable electrodes. This creates higher thermal efficiencies and narrower heat-affected zones.

    Since there must be an ionized path to carry out electricity across a gap, the mere switching on the soldering current with an electrically cold electrode posed over it will not start the arc. The arc must be catch fire. This is caused by either supplying an preliminary voltage high enough to cause a release or by touching the electrode to the work and then withdrawing it as the contact area becomes heated. Arc welding may be done with direct current (DC) with the electrode either positive or negative or alternating current (AC). The option of current and divergence depends on the process, the type of electrode, the arc atmosphere, and the metal being welded.
