Welding is a method to join two or more thermoplastic or metal pieces with the application of heat and pressure in adequate amount. It softens the materials and fixes them together as a unit. Different welding machines or welders help users to weld different machine parts, iron fittings, automobile equipment, etc. The functioning of most of these welders is limited, as they can perform only a specific process. However, some welders can perform multiple processes. These sophisticated machines can handle all sorts of processes like Stick, TIG, MIG, Air Carbon and Flux-Cored Arc Gouging and more. Let’s get to know a little bit more about them.
Capabilities of multiprocess welders
Different service providers offer their own version of these welding machines with functionalities that separate them from the rest. Some common capabilities to look for in these machines include appropriate AC auxiliary power, usually 2000 watts, remote control facility, availability in multiple configurations, such as 4Pak and 6Pak, and so on.
Additionally, some essential features to consider while purchasing or renting any of these welders include arc force, hot start, continuous output control, lightweight, compact & portable, availability of digital meters for preset welding output and adjustable arc control.
Multiple processes
Processes that these welders perform can include:
Gas Metal Arc Welding (GMAW)
Also known as Metal Inert Gas (MIG) welding, this method is most appropriate for fusing aluminum, mild steel, stainless steel, and similar materials. It is a regular welding method in fabrication shops.
Gas Tungsten Arc Welding (GTAW)
Also known as Tungsten Inert Gas (TIG) welding, it requires the operator to perform the welding task manually. It is useful in ensuring superior standard of finish, without perform the grinding or sanding work for cleaning.
Shielded Metal Arc Welding (SMAW)
Also known as stick or arc welding, this method is suitable for welding heavy metals with size 4mm and more. It is one of the most basic of all the welding modes, and is apt for construction, repair, and manufacturing processes.
