Multi-process welders are welders that perform a variety of processes and are typically used in automotive, transportation, agricultural, construction and fabrication industries. The basic functions which a multi-process welder is capable of carrying out are TIG, MIG, Stick, flux-cored and plasma cutting.

Each one of these processes varies slightly from each other, based on the physical nature of the welding and grants the welder specific benefits based on the required job and the desired results. Below is a brief description of the various functions and their intended uses.

TIG Welding

Tungsten Inert Gas welding, also sometimes referred to as Gas Tungsten Arc Welding and HeliArc, consists of a process which is performed by the fusion of a tungsten electrode which is non-consumable, which in turn heats the work surface or metal with an electric arc. In GTAW and TIG, shielding gases are needed to protect the welded area, while the intended usage may vary depending on the type of material, the design of the joint and the required appearance of the finished weld.

Most often TIG welds are performed on thin sections of stainless steel, as this type of weld gives one greater precision and strength of the weld, but it is more difficult to master and considerably slower than other weld types such as MIG welding. 

MIG Welding 

This type of welding, formally referred to as metal inert gas welding, is driven by an electric arc which is generated between the end of a consumable piece of wire and the metal surface being welded. Additionally, a shielding gas is released from alongside the wire electrode, which shields the work surface from contaminants in the air.

MIG welding was originally intended for welding of aluminium and other ferrous metals, but was later adapted for use with steel. This type of welding is preferred in industrial processes due to its versatility and speed, but is only used inside because of the use of a shielding gas in the process.

Plasma Welding 

Plasma Arc welding (PAW) or plasma welding is a kind of welding that is quite similar to that of TIG or GTAW (Tungsten Arc Welding), as it uses an electrode and a workpiece, with the main difference being the location of the electrode. In PAW, the electrode is within the body instead of outside like that of a TIG, and this electrode is directed through a copper nozzle. The plasma cutter arc is released in high velocity, and the main goal is to increase the energy of the released plasma in a controlled manner.

Many of the uses are similar to that of TIG welding, but plasma provides deeper penetration of the metal surface and higher tolerance to surface contaminants. The size of the torch is however considerably more bulky, which makes manual welding more difficult.

Stick Welding

Stick welders or Shielded Metal Arc Welding (SMAW) is a kind of manual welding. It uses a covered electrode and an AC or DC electric supply to heat the coated electrode.  Due to its versatility and the ease in use, especially as it comes with AC and DC power supply, stick welding is one of the most extensively used method of welding.

The coated electrode provides stability to the arc that is welded and also shields the molten metal by forming a shielding gas; the coated electrode protects the work area from contaminants. The primary materials which this type of welding is used on is iron and steel and this is mainly used in heavy steel structure construction and manufacturing sectors as well as in repairs and maintenance industries. Because of its versatility however, stick welding can is also used on aluminium, nickel and copper alloys. 

Flux-Cored Welding

Flux cored welders or Flux cored arc welding is similar to stick welding, but is however an automatic semi-automatic welding process. The flux cored arc welding process consists of a flux covered electrode and a power supply which is constant, with one of the major differences being that it does not require any shielding gas.

An externally fed shielding gas may be used, but is not necessary, as the flux itself produces gas and slag to protect the welding surface. The flux cored welding process is generally used on materials like alloys and stainless steel. Due to the easy portability and impressive welding speed, flux-cored welding is often used in industries such as construction.

Power Supply Importance for Welding

The electrical power supply available or required can greatly affect a number of factors when welding. It is important to first determine which power supply is available or which type of power supply is required before selecting a welder or a specific welding process.

Generally speaking a specific type of welding may rely on either constant current or constant voltage power supplies, which voltage responsible for the length of the arc, while current is responsible for the amount of heat generated.

The direction of the current also plays a significant role in welding, with common welding types such as stick welding and MIG welding most often making use of direct current. The polarity also plays a significant role in that it has great influence in the depth of the weld.

So, it is important to note the required heat, bead off rate and penetration required as well as the specific thickness and characteristics of the metal intended for welding when considering the type of welding process to select for a specific job. A welder extension cord may also be advisable if it is necessary to work further away from you closest power source. for more remote work a engine driven welder generator may be required.
