Topic: Flux core vs mig

[4RunnerChevy]

I had to literally blow up an ESAB to get a new mig.

[4RunnerChevy]

Sweet. Any reason you ordered a spool gun as opposed to the push/pull? Big price differece i suppose?

We are getting a gun cause running aluminum through the liner, screws them up.  Even if you get a Teflon liner !  Otherwise we have run a spool or two of dual shield, and we are doing mild with it now.  We might get the tig torch, cause we can run this welder from our generator, and tow it anywhere around the park

Do you find the preset settings to be to your liking for the most part?
How is the polarity switched?

The presets are nice, but I immediately adjusted them. The preset is a good starting point, it remembers where you left off in any mode.  Its a good thing because a beginner can step up, and an experienced welder can change up. You can always go back to default.   Polarity is done is done by the flick of a switch, to a different mode.  Pulse is awsome.

I can't wait. One of the main reasons for me getting it was the pulsed arc feature because I'm doing a lot of thick stainless vertical and I'm told it is great for that. I wasn't aware that it remembered what setting you last used. Good thing it does cause I rarely do. It's almost like cheating  
I'm almost bummed I have a 4 day weekend till I can try it.
I started off years ago with an engine driven Lincoln SA-200. This is so far from that it's not even funny.

Anyone can weld with the machines these days.  I still have to to run 7018 pretty regular though. Keep us updated when you get it set up.

With this and my recently acquires Thermal Dynamics cutmaster 52 plasma cutter I feel like a superhero.

I will be getting this at my work shop next week. Lincoln Power Mig 350MP. It's pretty sick. 350 amps, and will do stick which will be cool for carbon arc gouging, as well as pulsed arc mig. It is capable of GTAW as well, and push/pull wire feeding for aluminum and/or a longer hose because it can be equipped with a feed roller at the gun.
Not that it has any bearing on the discussion, but I'm stoked.
They told me to get what I wanted so this is definitely it.

you need to stop  brand dropping its not cool

Beg pardon?

I said I wasn't interested anymore but back to one of my posts earlier,  Beveling a T joint will allow the perpendicular piece to be penetrated well with the current settings on the welder, however the rest of the parent material is still at full thickness and less penetration will be achieved to the base plate and the full thickness piece just above the beveled area.  A way to overcome this would be to pre-heat the base plate with a rose bud as for the perpendicular beveled piece pre-heating it would most likely cause the welder to blow through the beveled area.  The better way to get even and equal penetration to both pieces of material would be to use an alternate form of welding like spray transfer.  And how often is it going to be realistically possible to pre-heat any metal near most of the welding projects that the members of this board are attempting.  If your going to try to convince audiences through proper debate you have to fully consider those you are trying to convince.  Most of the non status quo info coming into this discussion is irrelevant to the non certified homeowner hobbyist.

If you need to preheat the flat plate to get fusion when welding a beveled edge, you arent going to get fusion with just a fillet weld either. Think about it

Think about how much thinner you are making the beveled piece. My bad got sucked into an off topic topic,  debate one topic at a time or start a new thread.

[junya92toy]

I know, but you still add back material, Ive done it, hundreds of times, with a UT check. O btw, bevels arent aways a knife edge, you can be called for a land too of a certain size, with a root opening or not too.

I would agree with not getting into off topic debates, but it would appear that everyone including the author of the thread are enjoying this one, so why not?
Back on topic, any of the processes mentioned are completely capable of producing sound welds and assemblies, and a lot has to do with personal preference and budget. Some processes are better for use on less than clean metal or where wind could be a factor, but any of them can produce acceptable welds when done properly. None are really superior, some simply lend themselves better to certain applications. They all accomplish the same result.

Worth a look

The T joint and fillet weld are the most frequently used joint and type of weld.
In the same way the edges of the butt joint may be prepared for welding, the tee joint’s vertical piece may be prepared using a Bevel, or J shape. The preparation allows the Welder to penetrate into the root of the joint.
See examples below:

Brand Dropping

Mentioning that you're wearing an expensive brand of clothing, using an expensive piece of technology, or bragging about other items that you own which are of high value. Brand Dropping is similar to name dropping, the main difference is mentioning merchandise in lieu of a person.

[junya92toy]

I dont think hes a rep?

[yjay]

The idea never occurred to me. If it makes you feel any better my personal equipment consists of a 110 powered wire feed welder(using flux cored wire cause I'm too cheap to buy a bottle and stuff) and oxy/acetylene for cutting. I won't mention what kind.
Not a rep either.

I like the part where the steel sticks together.....
