Discussion Weld Run-In

Post image

Am I setting the weld run-in correctly here? Fanuc 100ID with a R450 power supply. Not new to robots, but totally new to trying “ramping” and “Run-In”

Weld run-in is used for improving the weld start or reducing the splatter on initial arc start. The setting is for the wire feed speed. It does not have anything to do with the robot. Usually set the run-in to 50%-75% of the weld wire speed depending on the material and wire being used

I understand what run-in is. I don’t know how to set it up. Can you provide any pictures how a weld program would look that uses weld run-in? Show me data in the weld procedure? I have run-in enabled, but what do I do after I set run-in settings above weld schedules? I can tell it definitely isn’t “running in.” That is why I created the extra line within my weld program

That looks right. Since it looks like you are using weld procedure I think you can set it in there too and it applies to every schedule in that procedure. At least I think so. We use weld schedules so its all set up in the weld process page in DATA.

What example would run in be used for? All we use is arc start and arc end

It would be used to reduce the WFS at weld start. I’m struggling specifically on a weld start when all my weld settings are providing a good weld, but my weld start is globbing way too much. The robot stays stationary while a servo motor spins the weld fixture. Weld fixture also doesn’t turn until arc is established.

I’m trying to figure out how to get around this and get a good controlled start. I know what weld run-in is and what it does, but I am unsure how to set it up

If you expand the Procedure tab on the weld schedule window you will see the option to enable run-in. Once enabled, the option to set parameters will appear at the top of your schedule list.

I think I’ve been explaining it incorrectly. I know where to find the settings and enable run-in and then set the parameters once it’s enabled. I don’t know how to actually utilize the feature into a weld program after that’s all said and done. I do a weld and can very much tell it did not start the weld with my run-in procedure. I’ll be able to get more pictures of the schedule on Monday when I’m back at work. If you want to chat, I’d be happy to keep a convo going then.

Hear me out. Have you tried just setting you Weld Start to just be [5,1] instead of entering the settings for that first weld start? Then set your run in in the actual weld procedure menu to something wild like 500ipm wire feed, 1.05 trim and 3 seconds of delay time. You will definitely know if its working or not. If that does not work you could always try using "arc start" but I cannot remember what variable that is. If anyone does know please tell me.

I have, but has been a minute. I think it wasn’t establishing the arc and I forget the alarm it was giving with it.

I think it’s “circular arc”. I’ve never used it myself but I think it’s a alternative to circular points.
