Welding is a fabrication process of jointing materials like metals and thermoplastic to create a strongly bonded material. Welding has various energy sources some of them are the electric arc, laser, gas flame, friction, electron beam and ultrasound.

In supplying the required electrical power for welding process whether it is constant current or constant voltage machine, generators are advisable to use for aiding the welding power supply in providing high voltage and high current in order to go on with the process of welding.

Generators are used for converting mechanical energy to electrical energy and are very useful for supplying electrical power on appliances during power outage.

Welding Generators, also known as welder/generator, are the one that generate power for welding machine without depending on power grid. Welding Generators has the ability to generate DC and AC current which produces 10,000 watts or more of power for welding equipments. A welding generator may be available as a portable generator, stand-alone generator or any other model depending on the specifications and design needed.

In using Welder Generator, the application and specification must be considered for accurate supply of power and for better usage. Here are some welding types:

Types of Welding

• Gas Metal Arc Welding (GMAW) – widely used at homes and suitable for stainless steel, fusing mild steel and aluminum.
• Tungsten Inert Gas (GTAW) – used for outstanding standard finish that doesn’t required extreme grinding and sanding.
• Arc Welding (SMAW) – most convenient type of welding which is ideal for construction, manufacturing and maintenance.
• Gas/Oxy Acetylene Welding and Cutting – uses acetylene gas and oxygen in producing flame that has the ability to melt steels.

Welding Generator varies in many specifications and sizes, and in choosing the appropriate welding generator, you must consider this things.

• Engine Type – choose if you are either going to use diesel, liquid propane gas or gasoline in powering up your welding generator.
- Diesel Engines – provide better fuel economy than the others and also don’t ignite fast.
- Gasoline Engine – preferably used in cold weather job location because it has the ability to turn on and start fast without an extra starting aid.
- Liquid Propane Gas (LPG) – is not commonly use but also an important alternative in replacing diesel and gasoline engine type if not allowed to be used in indoor application.
• Application – you must know the intensity of application needed for your project to secure the accurate power requirement of your machine.
• Portability – considering if you need to carry or move the welding generator it must be easy carriage and handy type.


Welding Generators are exposed in flames and compressed gases during welding procedure which may lead to fire and explosions if not given attention. Safety precaution is always a must and here are some safety tips for welding.

• Check if all of the connections and wiring are fixed and tight especially the earth ground connection.
• Ensure that all output terminals are well insulated.
• Do not perform welding process on locations with wooden floors unless it is secured with hot metals because woods are prone to fire.
• Remove all flammable materials.
• Never use damaged, worn, poor spliced or undersized cable to prevent the electrical shortage and electrical shock.
• Make sure that you always use a well maintained machine.
• Always remember to turn off the machine when not in used.
