Identifying a Proper Robotic Power Source for Welding Applications

Identifying a Proper Robotic Power Source for Welding Applications

While choosing a robotic power source for your welding applications is critical, it can be quite confusing. In addition to the numerous companies in the industry providing these today, there are many models to choose from which makes the exercise arduous.

A proper power source aids smooth operation of the welding robot. There are various considerations to make before deciding on a power source. For instance, establish, document, and evaluate the welding operations your business will use. This way, you will be able to match them with the available options in the market.

Material thickness and part intricacy is another crucial factor to consider. Establishing these parameters is an indirect demonstration of the duty cycle needed for the application. Remember to consider other electrical and communication parameters as well as the tangible capacity of the power source.

Such a comprehensive evaluation is critical when it comes to choosing the correct robotic application power source from an industrial automation framework. Below is an analysis detailing how to choose the ideal robotic power source for your welding applications.

Robotic Welding Types

Selecting a power source is part of outlining the tasks that need to be done with the same. Ensure that the power source can be used in your robotic welding application. There are various welding applications which include,

·         MCAW (Metal-Corded Arc Welding)

This application is similar to the GMAW. However, MCAW functions across a vast range of concealing gases and provides added flexibility with alloy configurations as compared to sturdy wire Metal Inert Gases (MIG). This application is executed on alloy steels, carbon-manganese, and welding carbon. However, it can also be utilized for stainless steel grades welding.

·         GMAW (Gas Metal Arc Welding)

Gas Metal Arc Welding is also referred to as Metal Inert Gas (MIG). This application utilizes a reel of wire either supplied by a peripheral wire feeder or a reel of wire. A welding gun supplies the sturdy metal wire. A direct current (DC) power source introduces and manages the curve between the metal part and the wire that needs welding.

GMAW utilizes a concealing gas to safeguard the weld pool from the surroundings. Remember, this welding application can be utilized in various commercial metals. Still, it can be implemented on a wide variety of material density.

·         SAW (Submerged Arc Welding)

This procedure utilizes a constantly supplied wire with flux or granular component to protect the weld area. This procedure is often utilized on robust plate applications which include functional extreme speed welding applications and architectural steel. This process produces minimal fumes which keep the air in the plant clean.

Success in welding technique depends on the choice of the right power source, consumables, application technique, shielding gas, and power source polarity. In order to minimize errors, one should choose to utilize the correct settings.

Once the work has been outlined, it is important to compute the effort that the machine will require. This effort is demonstrated as a duty cycle.

Duty Cycle

Duty cycle refers to the magnitude of welding time computed over a specific period at an estimated time to prevent damaging interior elements. For instance, a power source graded at a duty cycle of 50% at 250 amps shows that in 10 minutes, the machine will offer 250 amps for the first 5 minutes and cool for the 5 remaining minutes.

A 100% 290 amps are recommended when it comes to automatic welding applications. Remember, each duty cycle is computed for a 40 degrees Celsius ambient temperature according to existing industrial robot arm standards. Duty cycles should be minimized when this temperature is exceeded.

Welding Output

The required welding output is directly affiliated to the welding-type that needs to be done. For instance, people in search of an automated system should ensure that the power source comes with a 50% to 100% duty cycle and a more than 330 amps welding current.


By factoring the above guidelines, it will be easy to choose between a variety of power sources. Purchase from a reputable company and ensure that all the features you need for smooth operation of your application are available in your preferred power source. As the industrial robot arm makes its way in the welding industry, using the right power source enhances its operations.
