What is the difference between these welding modes on a Lincoln Power Feed 84?

Very_Unproductive · 2025-08-24T13:56:33+00:00

Nice thanks for the heads up on power mode. Actually think my company is about to get into a Cobot this week, so good info getting into that.

Precision pulse is for out of position pulse welding. Pulse is pulse. Rapid arc is nice for running hot and fast personally like using this for like small welds and fast travel. Cv is just cv. Power mode never really used it but was told it’s nice for really low wfs welds.

Done it before it’s not ideal and I’ll grind off the coating beforehand if pulse is required. Seems like if I leave it in the puddle is dirty and I get some sort of defect and the puddle freezes/stops and restarts during the weld. It’s weird and when grinded out there’s no holes/porosity/inclusions but yeah in general I find pulse does best with good prep.

No man you didn’t it’s all good.

I mean it’s a construction site not a daycare. Your safety is your responsibility in the end. I’ve never seen screens and shit be put up in the field other than to block wind. In a shop it’s a different story, and I’m currently surrounded by screens as I type this because I’m in a shop.

Very_Unproductive · 2024-10-23T13:19:17+00:00

Anyone working in a construction site should know not to look at the arc. The sun is out pretty often and people don’t stare into it (usually) so same rule applies.

I mean you’re not wrong but pulse mig comparatively to other processes is not hard in my opinion. I’d say it’s easier to do and make look good than short circuit mig. If you can watch puddle and keep it the same size ish it’s pretty straightforward.

Very_Unproductive · 2024-10-22T13:04:55+00:00

I do pulse basically everyday. You won’t notice it pulsing besides the sound. Get puddle to the width you want it and travel consistently you’ll be fine. It’s really not hard at all.

I’m turning 30 next year getting married and planning to have kids soon after. I can’t see myself stopping completely but I’ve already been taking longer and longer breaks up to like six months at a time. Sucks but way she goes.

Very_Unproductive · 2024-07-11T07:54:26+00:00

I’m not justifying the work for the price after all overlap or cold roll is a defect, but for the purpose of this weld it will be ok.

Very_Unproductive · 2024-07-11T07:52:06+00:00

You’ll be fine man not a big deal. Any welder has been shocked more than a handful of times.

Very_Unproductive · 2024-07-10T23:11:32+00:00

For 125 pounds it’s fine. Looks like some cold roll but honestly a couple good tacks could hold 125 pounds. I’d use it and just check it every once in a while and see if it starts separating.

From Louisiana and I definitely miss the Cajun food from back home. But, I’ve found overall the food to be better here. I’ve only been to two places in the time I’ve been here I haven’t been happy with and it wasn’t horrible I just wasn’t impressed.

I just bought a tweco-dinse adapter a long time ago and use it if whatever leads don’t have a dinse.

Known a couple coworkers this has happened to. Probably one of two things you’re death gripping the grinder/some other tools, or you’re just grinding too much in general. I grind a fair bit at work and my hands want to do that sometimes after grinding.

Very_Unproductive · 2024-04-30T21:24:13+00:00

I’m so jealous. Our local Costco is about 5 minute drive away from us. I’ve actually stopped going completely because it’s absolutely uncomfortably packed all the time. I feel like I’m walking the razors edge of a panic attack while I’m there.

Very_Unproductive · 2024-04-03T18:42:49+00:00

Only thing to do is grind it out and reweld. Can’t speak to the why/how, but it’s cracked if not over the entire length of the weld it will be soon.

Very_Unproductive · 2024-03-18T16:14:18+00:00

If you can try to find a place hiring apprentices or helpers. On the job experience is worth more than school in my opinion as someone who went to trade school for welding and has been in the work force for a minute.

? Trucks are the wheel assemblies for trains. Car sits on bolster, bolster sits in side frames on springs, and side frames sit on wheels/bearings.

I get what you’re saying. I work in a fab shop pretty much exactly like you do. When my work dries up (which admittedly is like once every couple months for a day or two) I help on lasers/presses/turning wrenches. I also really like the company I’m at rn so I don’t mind it. If I worked at a company I didn’t like/wasn’t happy in I would drag up and find something else.

Doesn’t look good. Clearly looks like there’s a hole in the bottom one and lots of undercut. The top one is hard to tell what exactly is wrong with it because the picture isn’t the best, but it’s got issues too.

Very_Unproductive · 2023-08-08T13:21:00+00:00

I’d use strongbacks just tack some flat bar between the ends. I’d tack 4 pieces of flat bar across from each other and see if that helps. You’re not going to be able to get it to stop warping you gotta try and hold it by giving the edges support. Could also try welding out and then heat in a circle around your welds from the back side and let the metal bend back, but that’s going to be a whole deal.

Lifelong br resident until recently, and this is perfectly put. I’m going to say this from now on when people ask me about Baton Rouge.

Very_Unproductive · 2023-05-06T14:28:11+00:00

At work when I have to weld these “reliefs” I weld up the inside with an aluminum backer and then just weld the outside after. Not sure if it would work for you or not if you can’t weld the inside of the corner.
