Hi. We have a motorman robot with fronius welling equipment. Our programmer is no longer in the company. We need to modify an existing program by making fillet welds larger. Have tried a few things with no luck. Any ideas?

Dear Experts , we want to guide a robotic welding arm to weld reinforcement steel mesh structures. These structures are up to 40 meters long, 2 meters high and 1.5 meters wide . They are used for bridge beams which our client makes for major freeway bridge construction. The weld mesh structures are then lowered into the molds where they fill the molds with concrete . They thread through the mesh pre-stressed steel cable before they pour the concrete. We would like to use a gantry mounted robotic arm which would travel along and above the weld mesh cages and the robotic welder would spot weld at a given interval at the intersection of the mesh to hold the structure together, instead of tie wire . The issue is that the mesh is never the same so we would need to scan the mesh ahead of the welding tip so to create a model, something like using SLAM process. This way the robot would know where to weld and its position at each steel rod cross section of the mesh that needs welding . I am wondering is there such a device already available or would we need to integrate the Lidar and the robotic arm ourselves. We have a client that has asked us to investigate the potential . We are look for a partner or a specialist to contract to help us with the application. Please contact me at brian@3dx.com.au . Regards Brian Rowland

Is there a programming methodology for Motoman DX100 or DX200 that allows for the specification of a series of welds with reference to a dictated origin, that allows for that series of welds to be copied multiple times with an offset referencing the dictated origin? eg, welding a part sequence that is repeated multiple times a specific distance apart. I would only want to do this to get the bulk of the points entered, then change from an offset reference to just the individual points so it is easier for an operator to read/understand/manipulate.

Is there a way to run a check run in auto with a motorman dx200 and miller auto access welder remotely i.e.. HMI? I know it can be done from the teach pendant.

I have a cell with 4 Kuka welding robots. They all weld at the same time. I have one robot, that at the end of the weld cycle leaves too much wire sticking out. The very next cycle if the wire is not cut off or backed up it will arc off and stop the cell. The wire feeder, torch and liner have been replaced and the problem still exists. Any idea of what could be causing this one robot with seemingly the same parameters to continually leave too much wire stick out?

We have acquired several IRC5 robotic cells. Upon modifying a weld start position with the modify position button, I inadvertently hit the message stating "Do not show this message again". The confirmation for the modpos therefore, is not showing upon using this function. How do I bring this message asking for confirmation of the modification? I'm guessing that a warm start will return the pendant to the default setting, but is there a another way to control this function?

We have an ABB 1410 Mig welding robot. At the time of jog move it shows MOTOR CURRENT ERROR and all movements are blocked and motor is in the OFF state. How do you remove this error?

We are installing a Motoman MA3100 in our shop, what would be some options and what would be the best way to keep the temp right for the robot to work?

I am using a Fanuc 120I with a servo torch and a Lincoln 455 Powerwave for .035" aluminum wire and we cannot get it to stop burning tips very often. The welds look great but it burns the tip at the start of the weld quite often. What causes this?

I'm using a Fanuc arc mate and can't get the weld to stop burning through my material which is aluminum. It's only the beginning of the weld and the end of the weld that burns through the material. What can i change so it will stop doing this and how do i change it?

The hand control screen is frozen - can't do anything with it. Can someone advise?

We are having problems with the and can't figure out why the welds look like they have porosity. We clean the tips and nozzels and it helps for a short time but can't consistently get a good weld.

Hi, we have an ABB robot (Unsure of numbers) and 1400 s4c controller. I can not get the controller and welder to communicate. I think it is trying to use Empty System parameter instead of the mig parameter or the pulse. I tried deleting the Empty one and got weird errors. Is there a way to change what parameter it talks to?

Hello. I am working on an ABB IRB 2600 with integrated power source fronius vr 7000 cmt. We have a big project, and we have been welding our product for 2 months now but we need to weld faster. For example I am running 5mm seam on sides of our product,13mm/s and when the speed is increased it cant give out so much wire and the seam is just getting smaller. What should I do? Use standard welding or pulse and try to go faster, or there is a way that I can do it with CMT? Max wire speed on it is 22 but it doesn't seem to reach that capacity.

We have an ABB 2400 M98 S4C robot and controller and a Miller Autoinvision power source. We don't have any control on the burn back procedure, not sure if the problem is with the robot controller or the power source parameters or other. Thanks

At my plant we are running several Panasonic TA-1600 manipulators with YA-1QAR series controllers and YA-1GJB series indexing tables. They come in a "Perform Arc" package from Panasonic/Miller. Ever since our Panasonic factory technician updated the software about a year ago we have been getting "No Communication" error messages. When this happens we have to power down the whole system to clear the fault. The operator will push the start button, the table will spin, then the robot loses servo power and drops out of auto mode, looking at the teach pendent the message "No Communication" is present. The fault always happens right as the table hits the home position (0 or 180 degrees) or very close. We have had various technicians working on this for over a year with no results. Has anyone here had any experience with this?

I see in RIA 5.10.4.2 minimum height of a fixed guard is 55". Does this assume the robot is floor mounted? What if the robot is on a riser greater than 55"?
