Insider Q&A: Questions Answered About Water-Cooled Robotic MIG Guns

A traditional water-cooled robotic MIG gun circulates a coolant from a radiator unit through cooling hoses inside the power cable, and into the gun neck and body. The coolant then returns to the radiator, where its baffling system releases the heat absorbed by the coolant. Water-cooled robotic MIG guns use much less copper in the power cables and thinner wall sections in the necks because their cooling systems carry away the resistive heat before it builds up.
Using either air or water to keep a robotic MIG gun cool is critical because it protects the components from damage due to radiant heat from the arc and resistive heat from the electrical components in the welding circuit. These insights will help you determine if a water-cooled gun is the best fit for your application.

Trends in Robotic Welding Guns

The through-arm style robot and through-arm robotic MIG gun make it easier to minimize downtime associated with cable management and reduce costs for cable replacement by dictating the length of the robotic MIG gun cable and accommodating increases in welding speed.
Robotic MIG guns may seem like a small part of the whole automated system, but the evolution of their design and functionality is having a significant impact on the cost, productivity and quality of an application.

Which is the Right MIG Gun?

Each MIG gun has its advantages and disadvantages. Water-cooled MIG guns are more expensive up-front and can require more maintenance and operational costs. However, water-cooled guns also are much smaller and lighter than air-cooled guns, so they can provide productivity advantages by reducing welding operator fatigue. Also, because water-cooled guns require more equipment, they can be impractical for applications that require portability.
Here are some insightful tips on how to weigh out the pros and cons when selecting between air- or water-cooled guns and light- or heavy-duty models.

Tips for Proper Liner Installation to Help Optimize MIG Gun Performance

Improper liner installation — which includes trimming the liner too short or having a liner that is too long — can lead to a number of problems, such as birdnesting, wire feeding issues and increased debris in the liner. These issues can result in costly rework and operator downtime for maintenance and repairs, which impacts productivity.
MIG gun consumables are often one of the most overlooked portions of the welding operation. However, choosing the right consumables, and using and maintaining them properly, can make a significant difference in gun performance and weld quality.

Robotic MIG Gun Options that Improve Quality and Reduce Downtime

The wire brake and air blast features shown on this robotic MIG gun are available as factory-installed options or they can be retrofitted. 
The wire brake and air blast can be used together or separately to help improve quality and performance in robotic MIG gun applications, leading to cost savings for welding operations.
