When I visit welding facilities around the country I get to see the ins and outs of many different welding processes, including the treatment, handling, and safety of their MIG guns and their general weld technique. I’ve seen both ends of the spectrum, good and bad.
When it comes to weld cell issues, oftentimes it is the simple things that are affecting its performance. Being able to know the basics and go through the basics will usually solve the vast majority of your robotic torch performance problems.
Usually when I'm meeting with a Foreman or Production Manager and get a chance to talk first hand to his or her welders, one of the most common topics that come up is their contact tips. The problem: they have to change them too much. This kills productivity for the shop, takes a big bite out of cost, and generally just creates a less efficient atmosphere for the welder to work in.
So why are your contact tips not lasting? And what are the problems that cause the contact tips to fail? How do you prevent them? I'm going to go through below the 3 most common contact tip problems I run across on a day to day basis, and how typically you can overcome those problems.
When you think of welding automation, cable assemblies are probably not the highest priority when evaluating options. But you may be overlooking a critical part of the torch as you go through all the different robot torch options out there. Without question, the quality of your cable assembly plays a key role in maximizing the efficiency of your automated welding processes.
