Miller Millermatic Flux cored MIG Welding

[TheHossHobart]

Fluxcore welding is a lot like stick welding.

[mccunecp]

look liek a lot of work to just switch the polarty I get a high current switch to do the switching saving time and ware and tare on the termals every time you have to take the nut off and then take it off. but I like the video good infor to learn

[MrStevilKneivel]

Check Craigslist for gas bottles. I picked up a 125 CF 75/25 full for $100 with recent 2010 hydro test. The deals are out there if you look.

[wwwweldercvfi]

Very good !

[Neseri2de]

Horses for courses!

If you cant use gas MIG then use ARC otherwise you will be dissapointed with your welds.

[TSorovanMHael]

Argon regulator......$150 (one time expense)

bottle of low cost Ar+20%CO2 shield gas......$20

30lb. spool of low-cost E71t-1 dual shield wire......$30

cardboard wind shield w/ duct tape.......5 cents

Making welds that are 100% stronger, tougher, faster, cheaper, far better looking, and lower-spatter. in other words, better in every possible way ..........priceless!

Note that a 30lb spool of that "self-shielded" garbage costs $75-$120. Still think you're saving time and money?

@TSorovanMHael i tried to go get argon bottle it was like 300 bucks where could i maybe find one online or somwhere for cheaper have regulator already cant find a bottle for cheap give me some ideas if you can, i bought this thing a week ago and it is like im trying to chase the wire and i put it on slow and burn it cant get it set right, it is hobart 140 but all i can do is spater or bead i can weld with stick alll day and i remember highschool using mig doin bend test is it welder or me thanx

[TSorovanMHael]

@patron4life1 Most weld gas suppliers will charge a deposit and a one-time fee to "rent" one of their cylinders. usually something like 150-200$ for 3-5 years. This covers upkeep on the cyl, which by law, needs to be tested and the valves rebuilt every couple years. Some of them will even refuse to fill cylinders they don't own for liability reasons. Anyway, you pay the rental, then you can take the cyl. back and refill it as often as you like and they only charge for the gas.

@TSorovanMHael you forgot $300 tank. and good luck getting all that card board around big objects. and by the way if your saying this is garbage then you are saying all stick welding is too. this has its place in the field. and they arent stronger, the fluxcore can penatraite deeper on thicker metal

[TSorovanMHael]

@coalandnuclear Thanks for the reply. Yeah, I forgot the bottle, that's a one-time expense too. doesn't really figure into the net cost of materials at the end of the day. I disagree about stick welding. The physics and chemistry that goes on with self-shielded FCAW are quite different from stick. For example In the former, wire manufacturers are forced to add excessive amounts of oxygen scavengers such as Si, Mn, and Al which in these amounts increase brittleness and impact sensitivity.

[TSorovanMHael]

@coalandnuclear all those dexoidizers simply aren't necessary in stick which by design the arc area is better protected from O2 in the air than self-shielded FCAW. Even under ideal conditions, it's difficult to get rid of porosity and worm-tracks with self-shielded FCAW. In normal steels, such excessive amounts Si, Mn, & Al would be considered detrimental impurities. Finally, penetration is a function of joint design, material thickness, travel speed, weld position, and most of all weld current.

[TSorovanMHael]

@coalandnuclear If your hard-wire MIG welds have poor fusion and/or penetration, usually it means you're not drawing enough current. One reason that dual-shield / self-shield penetrates better, is that elements in the flux such as potassium increase the conductivity of the arc, and increase the current vs. MIG. But the most common reason is that welders with MIG try to use "short circuit transfer" (a low-current process which lacks cleaning action), on material too thick to be appropriate.

[red666A]

Does anyone here knows exactly where to get MIG gas tank? FLux core burn to hot for aluminium and don't give clean welding look...

[DLEWIS488]

@red666A first of all you never weld aluminum with steel. you allways weld same fabric to fabric. 

[smokemanno1]

like he said on the vid you can not use gas in places with violate air such as out side that is the hole point of flux-core

[SthealthRaider]

sooo a normal mig welder can also work with flux?? just turn of gas and gas nozzle?

[GODZILLAMANASS]

and reverse polarity

[welderboy14]

@SthealthRaider yes any Wire Feed welder will Run with FluxCore Wire

[bez99probs]

I like how he says to wear safety glasses at the end and the asshole isn't. Haha

[DanaseVideos]

@bez99probs

He does have glasses on.

[pimpinpenz]

ya he is look closely

[arnoldii2]

he has them on.

[codycrowston]

butt flux

[agm65ccip]

smellycatpoop, I dont know what your setup was but I have been using flux core almost exclusively for years now and I have been nothing but happy with it.

[Zorack10]

I'd love to get a miller 120 v mig welder for about $300 bucks but I don't see that happening

[smellycatpoop]

Miller is the best!

But flux core wire - BLOWS!

[RestauranteChines]

Polarity does not only depend on the type and size of the wire, but also depends of the thickness of the base material you are welding, for example, if the base material is very thin, you use inverse polarity so you dont warm the base to much.

[Zorack10]

Where can I get these videos?

[robvk6]

youtube lol... just download them...

[farmboy30117]

I never realized that about polarity. I'll have to check mine.

[gpgab971]

@farmboy30117 Some machines have the instructions printed right on the inside by the spool. Some have a switch whereas others have to be set up manually as in this vid.

[nsdeuce]

great set of videos brother, good visuals, clear voice... i give these a 9/10(coulda been a 10, lacked a bit of info though)

do the same for stick and tig and you're my best friend :)

[41point2]

Thanks for the help.
