We know what we are doing day-to-day is not what most folks think of when they talk about welding… Good news, an old family friend has asked if we might help him start Mig welding with his old, but new to him Lincoln welder. Looks to be a solid old machine. I prefer them to any of the new ones myself. Be warm weather before he wants to do that, but it’s just around the corner.
I’ll ask nicely and I’m sure he’ll be fine with me taking pictures as we go, to share. We’ll walk through the machine, how it works, how to keep it working, little tips and tricks we’ve learned the hard way. He happens to have a gas-shielded setup but everything we’ll look at will apply to flux-core too. I’m looking forward to visiting with him, and his lovely wife.
Couple things we talked about already, I suggested he run a search for the manuals, he looked online and found the operator and technical manuals for his machine, and downloaded those. I imagine he’ll print those out.
I did tell him about nozzle dip, it’s a commercial product that helps keep the tip cleaner. Dad used bacon grease. Smell it for miles. It worked. Lard probably would be better. Dad DID clean his grease of course. Knowing the preferred way, and what works is always good.
I remarked that when I started I stuck the mig wire right to the tip. I’m still good at that. Nozzle dip helps with this. The tip can be saved by breaking as much wire as possible off, have to take it all apart to cut it loose from the inside, then file the outside gently until it’s flush.
Those little cleaner sets with round files that fold out, used for cleaning gas welding tips do a fine job of poking the last bit of wire out of the hole. Smoosh it in the in the nozzle dip deep enough that the inner part that the wire feeds through gets dunked, and go again.
A wire cleaning felt pad and the solution intended for it saves all kinds of trouble later. Keep the wire clean as we go and we aren’t yanking the liner out of the feed line and trying to resurrect it when we need it to work NOW! Both the solution and the felt pad were shown here:
Just clip the felt on the wire between where it comes out of the spool and the tensioner / feed rollers. Dribble a little solution on it once in a while. Change the pad sometimes if it’s cruddy. Clean wire welds nicer too. We just get it from our local supplier, Indiana Oxygen, in Seymour but it looks like walmart carries it at least online.
If you are really interested, the metal cored wire is sweet. Here’s an article about it that covers it much better than I can:
All introduction level stuff, which IS the place to start. Not claiming any particular expertise here, just talking about what we find works.
Our friend was concerned it would be hard to learn. In our experience most folks are making good solid welds in an hour or less. They can put a lot more time in and keep making prettier welds, but that level of effort is not appropriate or needed for most things.
Seems to come a LOT easier to those who can write cursive. Another unforeseen outcome of eliminating that from our school curriculum. Sigh.
I happen to think welding would be a GREAT prep. We have enough solar panels to run a small unit direct on a decent day and everything we’d need to get it together. I’ve looked at it and we could do more of course but I don’t see much need for it in ordinary situations.
If everything went to … well … you know it’s looking a little dicey out there, the ability to do welding repair would be a pretty hot business. Pun intended
So we’ll keep posting about whatever we’re making and I’ll soon be better situated to start posting a lot more practical stuff for the level most folks actually need to do. I’m pretty excited about that! Something to look forward to and someone to share it with. Our definition of happiness.
