Cable assemblies are not likely to be the top priority in your evaluation of options for welding automation. While you’re evaluating all of the robot torch options available, you might be overlooking one crucial component of the torch. It is clear that the quality of your cable assembly will play a crucial role in optimizing your automated welding processes.
The torch’s cable assemblies do the same thing for you: they provide all the power from the wire feeder to your contact tip and all the way up to your filler. It is best to have very short downtime between welding operations. For this to happen, you will need a good cable assembly. A superior cable assembly increases production, quality, and profitability in your welding cell.
You need to understand the characteristics that distinguish a good and bad robot welding cable. You can tell if a cable is of high quality by the physical and spec features it displays. This will help you to determine if it’s suitable for your weld automation. It’s crucial to ensure that you have the right cable assembly for your specific needs. This refers specifically to the cable rating.
The rating of the cable should correspond to the welding process. You should also know the current going through your cable and the duration of its duty cycle. A large cable won’t transfer current in the same way as a properly sized. It is a waste money and resource to purchase a cable with a higher rating than what you require. A 600-amp cable won’t work faster or better if you have only 300 amps. If your machine can only handle 350 amp, a 600-amp cable will not work.
Physical Characteristics a Good Welding Torch Cord Cable
A good cable assembly will provide good wear protection. Insulation and cable covers are necessary to protect the cable against the elements. But they should not be so rigid as to limit the cable’s flexibility.
A worn cable could result in reduced current transfer, increased resistance, hot spots and other safety hazards. This can make your robot fall, which can have an adverse effect on production.
You should inspect the quality of the cables before you look at the options for cable assembly alternatives. You should pay attention to the following:
Cable is crimped equally on both ends
Cable has no weak points or thin spots
Properly sized Copper to meet your amperage needs
Cables to control robotic torch cables for over-arm robots
When installing a robotic cable assembly over-arm, it is important to ensure that the correct length cable is used to extend the robot arm and reach certain welding points. A cable assembly that is pulled and pulled often will wear more quickly.
Bad quality or poorly made cables will break more quickly under extra stress. The cable may have problems feeding the wires due to repeated bent and twisted.
You want to get the most from your cable assembly. It’s important that you find the right amount slack so it doesn’t limit your arm’s capabilities but doesn’t wear the cable too much.
Robotic Torch Cables Through-arm
A cable is required for through-arm assemblies. This cable has the same functions and functions as an overarm system. Cable length is the biggest and most important difference in a througharm system. There is very little room for deviation from the specified length.
Most specifications for through arm cable length are within a few micrometers. This is very different from an over-arm cable system. A plus or minus six inches, or even a foot, will be acceptable.
Cables for Water-cooled Robotic Torch Cables
Water-cooled assemblies of cable are another option. Because they dissipate heat during current transfer, water-cooled cable assemblies are great. A 500A, air-cooled, cable is just 3/4 inch in diameter. While a 500A, liquid-cooled, cable is only 3/8″. The neck of a water cooled assembly is also water-cooled. This means that the water will drop to the tip-holder to help dissipate current transfers heat and reflect heat from the contact tip. You might be interested in hybrid cable assemblies, which are water-cooled.
Cable Assemblies with Hybrid Robotic Welding
In hybrid cable assemblies, the cable is air-cooled. Your front ends (neck, contact tip holders, etc.), are water-cooled. The hybrid cable assembly has a front end that is water-cooled while the cable itself is air-cooled. It means you can still enjoy the benefits and cost savings of an air-cooled, water-cooled front end.
Hybrid cable assemblies might not work best for your specific welding process.
It is crucial to evaluate all of the options available when choosing a cable to support your welding automation processes.
