Improving your welding?

This is a loaded topic that has resulted in a dynamic discussion that is causing some static.:D :drink:

One other thing that I find puzzling. How come it's called static electricity and not dynamic electricity when you get a shock touching the stove or the fridge door? I'm sure I'm not the only one who's jumped dynamically when this happens. :confused3:

Good question... I am not even going to approach that subject! There was a reason I switched from electrical to mechanical engineering midway through my degree and Arc... you might be getting to the reason. My dad was an EE but I just couldn't grasp (or more like it just didn't interest me to chase sparks). Figured part way through that a mechanical education might prove more useful personally as well as professionally. Little did I know how it would benefit me years later in an internet forum discussion as well! :laughing:

I was walking across the carpet in my socks. The buildup of static caused a sizeable arc when I gave my honey a hug. The results was really dynamic as the sparks flew from my finger tips when I touched her arm.

...and why do we drive on the parkway, but park in a driveway? :)

To bring the thread somewhat back on topic ...

I think the " pros " go a little overboard on the *every weld must be perfect * theme as well as tending to forget that not a lot of folks can sink a few thousand dollars into what is essentially a hobby or a chance to play with a new area of toys (tools) given that they can do what they want/need to do for a few hundred bucks. It dont take a lot of heat to weld up a mower deck or fix the patio chairs for momma .
That being said , I am not going to learn a damned thing from a " good enough " welder with his 110v mig . I can already farmerweld and most of the time it holds . Besides , I don't own a mig of any voltage , and honestly am not at all worried about this gaping hole in my tool lineup . What little thin stuff I need to weld I load up and haul the mile down to the neighbors to use his big ol miller mig , He even sets it for me and chews the fat while I glue it up .
I started off kinda biting on the pros , so lets look at the other side . If you dont want to be told exactly what kinda tool you are with your tool then don't post pics of a cold lapped poorly designed piece of crap and ask " how'd i do " expecting all the praise for being the special snowflake that you obviously are . You WILL get some honest opinions from folks who actually know how to build stuff. You might not like said opinions but at least imo you kinda asked for it . If your going to spend a couple of hundred bucks to weld the patio furniture and mower deck that is fine and have fun with the machine within its capability . Dont however go to building trailers or welding up the drawbar on your tractor with it and expect anything resembling a happy outcome .
Lastly , and for both sides ... Its the INTERNET guys ! Think about that .. You are arguing with someone you never met , never will meet , and wouldnt know if you bumped into them on a city sidewalk . It can only be personal if you make it personal when you set at the keyboard .

Edited to remove a mild profanity that slipped by MY filters .

I think I can agree with pretty much everything you have just said. I will address the gaping hole in the tool box you eluded to. One doesnt need to spend a ton of money on a competent machine. I own the big blues and reds, but I can see a place for the greens and yellows of the cheaper machine. For a hobbiest, One doesnt need 100% duty cycles, They just need something that will do the job. I have a special love for the old lincoln Tombstone ac/dc machine I traded to my brotherinlaw. Those machines will handle just about anything the old farmer can throw at it. Yes it is a 220v machine, but used ones can be found for the fraction of what a decent 110v mig machine can be bought for and you save enough to pay for having a proper plug installed to plug it into. Maybe even save enough to add a scratch start tig rig to boot. Prefer mig, while I am not an import person, some of those off brand machines get pretty good reviews when researched, and are a lot cheaper than red or blue. Then there is also the solution you suggested of going to a friend when you need something to really hold. I let friends use my welders all the time. Its not something I see a lot of, but I would rather they borrow my welders and do the job right, than have them cobble something together that might get me killed if I meet them on the road. Recently, I have been letting a young fellow use my Idealarc to practice for his 6g welding test. Hes just starting out and cant afford a high dollar machine and doesnt own a place to store it if he did own one. For me its a win/win. I get to learn from him, so letting him use my equipment provides me with an opportunity I wouldnt normally be exposed to. I can already see a big difference in my tig skills. But nothing I am going to take a picture of yet.

I'm sure you could learn a lot from someone who's going for a 6G test. Sometimes it's the really simple things that can make all the difference in the world.

On another site I ran onto this video.

While it is on O/A welding techniques and is rather long (43 min) it really brings up some fantastic details that I think apply to the discussions about low power welders.

Yes you have to do an analogy between tip size and amperage of the Mig machine but the discussion of penetration, cold lap and the heat of the puddle and the base metal is quite good (IMO). The results of inadequate penetration, cold lap and weld strength as the weld flexes is a topic that is independent of the type of welding that you are doing, whether it is O/A, stick, mig, or tig.

If not interested in O/A safety and setup skip the first 20 minutes or so. (20:15)
