Welding Machines
Welding machines are used to join and weld metals and alloys, and hold an important place in the metalworking sector. Machines suitable for use in different areas are produced to ensure high quality and cost-effective welding processes.
What Different Types of Welding Machines are Available?
Different types of welding machines have different features according to such factors as welding technique (e.g. as arc welding), type of current, etc. The welding machines that can be supplied by Gedik Welding can be listed as follows:
Manual Metal Arc Welding Machines (MMA)
Coated electrode arc welding is a manual welding approach in which the heat required for welding is generated by an electrical arc formed between a consumable coated electrode weld and the workpiece to be joined. In the process, the arc releases energy that melts the material. Coated electrodes, which consist of a coating and core wire, can be divided into rutile, acid, basic and cellulosic groups. Their chemical composition affects arc stability, material deposit and penetration depth. MMA welding machines are often preferred for aluminum alloys, stainless steel, cast iron and copper material processes. These machines have the advantage of being lightweight and portable, and can be used in both indoor and outdoor environments.
Gedik Welding offers solutions for the needs of all users through the broad range of products under the Gekamac brand, featuring both inverter and conventional type MMA welding machines.
Our RKM-series conventional MMA welding machines are mainly preferred for steel construction works, such as in the shipbuilding sector, and stand out with their durability under heavy working conditions.

TIG Welding Machines
TIG welding is an arc welding process that uses tungsten electrodes to achieve the heat required for the melting and joining of metal parts. These machines are also known as argon welding machines, as argon is used as the shield gas. As argon is colorless and odorless, the visibility of the welded item is ensured throughout the process. Only a minimum of spatter, smoke and sparks is observed.
TIG welding machines enable precise, clean and versatile joints on any metal in a wide range of thicknesses. In addition to the possibility of vertical or horizontal processes, these machines also offer corrosion-resistance and strong welding performance as advantages.
Gekamac Power TIG and PowerPlus TIG series TIG welding machines provide superior results when welding of different materials, such as unalloyed steels, stainless steels, aluminum, nickel, copper and titanium alloys. Gekamac inverter TIG welding machines make use of pulsed, synergetic and energy efficient PFC (Power Factor Control) technologies and a wide range of products, and provide superior control of precise welding parameters.
MIG/MAG Welding Machines
MIG/MAG welding machines take the heat required for welding through the melting and continuously fed electrode and the resistance created by the welding current. In Metal Inert Gas (MIG) welding processes, noble gases are used to facilitate the melting of the metal electrode. The MAG welding method was subsequently developed by working on different metals making use of active gases. MIG and MAG welding machines differ from each other in terms of the gas used and the metals processed. The MAG method, which makes use of carbon dioxide gas, is suitable for welding low alloyed or unalloyed metals. In MIG processes, argon and helium are used, allowing many metals such as aluminum, stainless steel and steel alloy to be welded.
Gas Welding Machines in production areas Gekamac MIG/MAG welding machines, GKM-series conventional and Power and PowerPlus series inverter-type welding machines are preferred in many different sectors.
GKM series welding machines have risen to prominence due to their durability in challenging working conditions, besides their compact types in the wire feeder unit, they offer welding solutions with detachable wire feeding unit and different output current ranges.
Power and PowerPlus series welding machines provide superior performance in the welding of unalloyed and low-alloyed steels, as well as materials of different thicknesses, with stainless steels, aluminum, copper and different alloys. Different types of Gekamac MIG/MAG welding machines feature synergic pulse mode functions, allowing the adjustment of such parameters as pre-gas, post-gas, starting amperage, output current time, down flow time, crater filling and arc spot time before welding, bringing both practicality and high quality to welding processes.
Submerged Arc Welding Machines
Submerged arc welding requires the formation of an arc current between the workpiece and the welding wire. Welding processes generally involve the melting of the weld wire and the partial melting of the metal part. As the arc is maintained in submerged arc welding processes, this method is referred to as “submerged arc” welding. Alkaline-earth metals and silicate are used as shielding gases in this method.
Various submerged arc welding machines are for the creation of large steel construction components, and in shipbuilding, the heavy metal sector, and in coating and filling applications. Besides joining metals, it is also used in modification processes. The main advantages of submerged arc welding machines include energy and electrode savings, deep weld penetration, fast processing, and smooth and uniform weld seams.
Power SAW-series Gekamac welding machines are designed for use under heavy working conditions, and provide top welding performance in submerged arc welding processes due to their precise adjustment control, leading to high customer satisfaction with tractor and automatic flux collecting unit, single axle and tandem tractor options.
Plasma Cutting Machines
Plasma cutting is involves the constant ionization of compressed air, for which a direct current power source is used to ionize the compressed air to turn it into plasma arc. Plasma cutting machines, process operation only on conductive metals and can be used in cutting and grooving operations. Reduced labor and operating costs, and easy cutting and transportation are just some of the advantages offered by these machines.
Gekamac Power Cut and Power Plus Cut series plasma-cutting machines provide high performance in the plasma cutting of different materials such as unalloyed steels, stainless steels and aluminum. It allows the precise cutting of materials with a low heat input, thus minimizing the distortion of products with different output current ranges and materials with different wall thicknesses.
What Factors Must be Considered When Choosing a Welding Machine?
The welding technique and type of welding machine required should be determined prior to choosing the welding machine. There are preferred welding techniques for different processes, such as MIG/MAG (Metal Inert Gas or Metal Active Gas), MMA (Manual Metal Arc Welding) and TIG (Tungsten Inert Gas). Aluminum, inverter, portable or MIG/MAG welding machines are used for these processes. When choosing a MIG/MAG machine, due consideration should be given to the weld length and the plate thickness. A pulsed welding machine is often preferred for welding aluminum. AC/DC welding machines can be used for TIG welding.
Whether the welding machine is to be used continuously or occasionally is also a significant point. Accordingly, a welding machine that meets all needs and that can be operated at high or average power is often preferred. The requirements of the welding machine in terms of mobility and size can also be determined.

Technical Specifications of Welding Machines
Welding machines operate on direct (DC) or alternating (AC) currents. Energy processing systems are used to reverse or convert these currents. The machines operate with both gas and electrical energy. Electricity from the grid varies between 25 and 50 Volts on average. Whereas electrical models are resistant to high currents. While an average welding machine is resistant to low currents, those used on production lines are protected against high currents.
Where Are Welding Machines Used?
Today, welding machines are utilized in every sector and in all operations in which metal parts need to be joined. Welding machines are used to join metals for different purposes in many different areas, ranging from large-scale projects such as shipbuilding, bridges and railway constructions, to small-scale modifications.
