icecube508 Best advice.. Learn to weld the material you want weld with scrap pieces.. Use the guide inside the welder for initial settings and just do it. Experience it and learn from it.. Books and videos only do so much.. Its all hand eye cordination .. The rest will come with time.. Dont be afraid to adjust settings high pto low and same with wirespeed that way you know what the welder is doing patient and have fun with it.

No !!! It's just sometimes people post things here that will make some people think they can't do it... I didn't take any school at all,,(self tought)..I got certified in many different type's of welding... A lot of what I was certified in was X-Ray weld's.. If you have the WANT to learn,, You WILL learn..Yes some schooling will help jump start you... But you can move forward witout it..

tech69 I agree. probably has a stuttering sound to, right? When you turn the wire speed up up you'll hear the frying bacon sound you want to achieve, but remember, you can achieve that sound every time you turn up your amps as long as you turn up your wire speed too, so it doesn't necessarily mean you are where you want to be, just means it's a good setting for some metal thickness, but maybe not yours. The key is to find the highest you can go with that sound
where it won't burn thru with quick tacks.

To make life easier I have a couple settings I have jotted down...

open butt weld setting

bigger gap open butt weld setting

plug weld setting

3 layer plug weld setting

My plug weld setting is my settings I use to also weld a seam where it's flanged under it or welding the edge of a lapped panel. My bigger gap open butt weld settings is also the settings I use to tack close pinholes where it doesn't call for a patch, if it burns away then I determine the metal is weak and need a patch. My 3 layer plug weld settings is also my settings for welding 16 gauge lapped for brackets and what not, or a plug weld with 16 gauge.

All these settings are simply a starting point. A lot depends on how straight the line is. If it's not so straight I'll probably have to turn up the wire speed a tad, but I don't sit there and test metal. I already know the welder. I'll sacrifice a tack or two and adjust by sound and what the wire is telling me. If the wire is doing what's happening to yours I need more wire speed. If it's pushing the work away and leaving big wire ends it's too fast. My goal is the flattest puddle I can make with the right sound. This means I must do fast tacks or it will burn thru. Sometimes a slightly slow wire speed will get you the best welds but are inconsistent. The sizzle will give good welds no matter how you move the line around while moving to different welding spots. some welders are also quarky. Some don't work the same every time, mainly old ones. Having a new miller will leave you awesome welds every time.

NEW INTERIORS Sounds more like your wire feed speed is to slow..
01-31-2013 08:27 PM
MARTINSR You likely have a worn out tip or the wrong size. Your tip size needs to match your wire diameter. Have you checked that? Also, cutting the wire off before you strike the arc the better off you will be to, the wire "pokes" the metal making a clean start.

But I would say it's likely your tips wrong or worn out.

wire sticks in tip

I am in the beginning stages of learning my mig welder, a Miller Autoset 180. I am getting to the point I can occasionally make a decent weld, and join two pieces of metal together.

My problem, a lot of times when I try to start a weld, it just "pops" briefly when it strikes an arc, and the wire sticks in the feed tip. If I turn the clamp on the feed roller up, the more likely is it I get a "bird nest" starting.

The problem is more pronounced with .024 wire, than .030 wire.

new design welders

I have 4 welders, there is a big difference in what they will do.
The new inverters are a lot smaller and lighter. The old Lincoln ac tombstone buzz box does ok for farm machinery repair. It can be moved out to a power pole we have at a pump on the farm. I bought a used Lincoln Square wave Tig 255 , it is a big heavy machine, It will do tig and stick It has ac balance for tigging aluminum. My Lincoln sp200 Mig is also a big heavy machine, both need a forklift to move. I have an old Airco ac-dc hi freq I keep in the other shop. Not as good as the 255 but I can stick weld with Hi freq, easier welding rusty dirty farm machinery. I like the Duty cycle on the bigger welders, I can weld all day with one and not overheat it.

What is really amazing is welding with a 220 3 phase. I was blown away with it at a shop I worked at with one. You could just about weld thru grease or something, it was amazing. From what I understand about it, as you mentioned the 110 is harder because it is one "wave" of current, while 220 is two making less of a "skip" from one arc to the next. The 3 phase gives you three, so it's of course even better.

We get a lot done with the 110 at work, we have about six of them and they do a heck of a job as long as you aren't trying to weld something too heavy.

MARTINSR Good stuff Henry, you hit on something I really believe in, weld hot! If you aren't blowing thru practicing you aren't welding hot enough. It's easy to lay something on top that isn't penetrating worth a darn. But start out welding pushing it and burning thru once in a while and learning the limits. It is much easier to back off a little than to push it more I have found. Besides when welding sheetmetal the faster you can weld it the less heat you have created.

tech69 reading up on tutorials is the best start then lots of practice. You must get used to the right sound, right wire speed, and right voltage. You can have the right sound and not have everything else right. My rule is the right sound as high as I can go without burning thru. Sheet metal is always quick zaps and after some experience you will find yourself wanting good light to aim at the places with most metal. Like if you lay your initial tacks. You then want to go back to an earlier tack and lay another one overlapping that one. It will not only help you with dissipating heat, it will also leave you with cleaner welds through out and not just a scattered mess. So experience helps you with finding right setting per situation, learning metal characteristics, learning your welder, and getting your style of welding down. Some guys like to weld with one hand and don't care for light. I like a bright light, one hand as a stabilizer, and the other on the trigger, a fresh cut wire, and I just have a bunch of things I do that can only be taught with experience. So reading will give you a good general idea but practicing on old fenders will help lots. Practice on 18 gauge if you plan on doing an old car. It helps to just cut squares out and re weld them in somewhere else, then practice fabricating a patch for the hole you just cut. This practice will help you when you need to make patches. it helps. After a while you will make any patch you want and never have to re cut it but just shave off a little here and there.

Here is that "Basics of Basics" .

Print it out and read it a few times and get out there and practice.

NEW INTERIORS Practice,,Practice,,Practice,, is one of the best ways to learn to weld...

Know the old saying...Practice makes perfect...
01-30-2013 08:04 PM
OneMoreTime Practice..I only weld occasionaly now and find I need to run some bead to get my hand back after a layoff from welding..Once you get the hang of it though it can be picked back up fairly quickly..
