Mig welding is just another name for Wire feeder welding. The fundamental idea behind wire feed welding is that you use a welding wire that constantly feeds through a MIG welding gun when you grip the trigger.
This is a nonstop welding process. You keep your finger on the trigger and the base metal, welding wire touching you can do wire feed weld all day. There are many different types of welding wire. You can use for many different welding applications.
Welding wire is the most commonly used for more than likely an AWS ER70S-6 classification wire. This welding wire is used fabrication shops and all welding for many different types of welds.
A cover wound wind of wire will be evenly wound onto the spool from left to right with each and every layer of wire in order to sitting next to the other. This type of process a lot better for wire feedability as there will be no bends and little kinks in the wire feed.
Random wound will be exactly random wound wire in any old type of fashioned.Because the wire is wound on the spool with each and every layer in a random fashion, the wire will cross over itself a a small amount of times. The spool starts to fill up with the wire feed, each and every time there is a intersect of the wires it can make a little bend in the wire.
These little bends in the wire can damage your wire feedability which in turn will affect your overall weld quality and feed.
When you are using a MIG welding machine or a wire feed welding machine you have welding consumables that need replacing on a regular basis. Every MIG welding machine gun will have a shroud and contact tip or a nozzle. And then depending on which type of brand welding torch you have there will also be a gas diffuser or some kind of insulator.
I guess that most home welders or DIY will use what is meant by gasless welding wire. This process is also known as a flux cored wire. Be careful though because there are two different types of flux cored welding wires. There are a lot more than two, but for general home welding wire feed make sure that you get a gasless MIG welding wire feed that is an E71T-GS.
Now if you want to do decide to use a gasless MIG welding wire you are going to have to modify the wire feed rolls. The reason for this mig welding wire is because it is a flux cored wire the wire is not solid all that way through. The flux is on the in the interior of the wire the wire is very soft.
So if the wire diameter is for dispute sake 0.9 mm you need to use a 1.0 mm get in touch with tip. This will really help with the smooth feeding of the wire and allow better welding.
Finally you’re going to have to use a a little larger get in touch with tip for when you use a flux cored wire.

How to justify Robotic MIG Welding over Manual Welding ?My shop employs Manual MIG Welding to Weld Structures that make an Earthmoving Machine producing 20,000 units annually. I want to move to Robotic MIG Welding. How do I make a strong and convincing justification ? What are Pros and Cons and how to best address Cons ?

ok ok
But you have to promise to watch my new beef jerky in the oven video …lol
You have lots to learn in such a short time. Here is a link that you will find most helpful. Click on MIG Welding. Good Luck !
Yes, always disconnect the battery when welding on a vehicle to avoid damaging the electronics. Remember to disconnect the negative terminal NOT the positive one.
You should't have a problem providing you use the correct diameter roller AND you are using the same sort of wire! (steel, stainless or aluminium). If you put mild steel wire in a gun that has only run aluminium it tends to stick.
i have seen worse welding from 30 year olds realy nice job
thanks
you’ve got some pretty good videos and now I’m thinking about buying that little arc welder…. How thin of metal can it do and can you make a video trying the welder at all amp.
Do you recommend a certain brand of flux wire? And is it hard to make the welds look decent?
I would recommend Lincoln Electric wire it’s nice and you can make pretty welds with any wire it just takes some practice and if you shine ‘em up, you can get you welds to look like TIG welds!!!
I used it to make a “suit of Armor” like dude that was made of tacked pieces of paper thin tin like steel and it worked if I hit it real fast. I mainly use it for 16gua-3/16ths/ Sure I’ll make another video with it turned up. I’ll go do that right now as a matter of fact.
On MIG welders with a wire feeder you simply pull the trigger to start the arc. On a arc welder using a welding rod, it is a bit more tricky. There is the bump method and the strike method. With the strike method you touch the rod to the work as if you were striking a match. Use a short stroke so the arc won't go out. On the bump method you touch the end of the welding rod to the work piece and a pull it back just a little to establish the arc. Both methods take practice and some trial and error. You must have a good ground connection to start any kind of arc, no matter what kind of welder you are using. This is even more important when using those small, home type welders.
Some professional welders prefer one or the other method, some use both from time to time. Just practice until you can get an arc established and maintained.
Make a metal coffee mug with copper. Use a flat copper plate. Cut it to size and using the bending machine turn it to a cylinder. Solder the seam. Then, Solder a flat plate on the bottom and cut around the base.
Then take a copper tube and make a handle by cutting roughly 6 inches of 1/4 inch dia pipe , press the ends and bend them inwards so you can solder it to the cup. Make sure you solder to the opposite end of the seam of the cup itself.
enjoy…
That weld looked pretty good. better than I everd did with that machine.
ok thanks. I have a REALLY tight budget so i would rather use cheap wire..but i still want the weld to look and perform decent. Im gonna lift my lawnmower about 4 inches so i need it strong and i want it to look as good as possible so i was just asking. Thanks a lot!
I would recommend that you do the learning first…and buy the welder last. The research you do into the various welding processes, will ultimately help you with your choice of machine.
100 amps is not a lot of heat in welding terms. And unless you are quite familiar with the rules of welding, you may produce unsatisfactory welds for a project as important as a trailer.
Go to the Miller and Licoln Electric websites. There is lots of great information there. Both have "learning" sections, with lots of information.
Consider if you will be able to use your welder for future projects or rapairs. If so, it may be worth your while to save up, and get a machine with higher amps, made by one of the big companies.
Learn all you can before you make your decision. Also, the book WELDER'S HANDBOOK by Richard Finch might be a good read for you. I think you can get them at Lowe's and Tractor supply, and I'm sure you can order it online. It's a great overview of welding.
Be safe. Learn all that you can. Then practice. THEN make a trailer. Welding for your own purposes is a lot of fun…and you might find all sorts of things to make once you get the hang of it.
