Another looking for a flux core MIG welder suggestion thread

[etpm]

I have some farm welding to do to make an adapter for front bucket to use on other machines. I’ll be using 1/2” steel plate. Have Millermatic 211. Have heard that using flux core wire with shielding gas will make deeper welds. Any thoughts on this? I know I can’t do a one pass weld, will need to build up. If gas + flux core wire is better I might try using. Thanks.

There is a welding process called dual shield that uses a flux cored wire along with shielding gas. It is used for putting down lots of metal fast. For regular flux core wire adding shielding gas won't help at all. To get better penetration just pre-heat the work. Get yourself a propane weed burner and heat up the plate. Even heated to 400 degrees will help a lot. Been there, done that. More than once. I learned this technique from an excellent teacher in a wire feed welding class.

I'm in the few-times-a-year category; I'm mostly working on 11-18ga stuff with very occasional 3/16-ish stuff.
I have a very old Miller 130 mig and it manages surprisingly well. Obviously you can't pull a very long bead on the hottest setting, but you'll eventually get the job done.

From the requirements that the op gave, I think a small mig unit sounds ideal. He's not looking for a high duty rate unit; he needs to occasionally weld something.

One thing I've found really useful with the little mig is that you can actually pull a 1" bead with it hooked into a 100' extension cord (watch for slag catching grass on fire lol). I had previously run it on a 3k generator as well.

Every few years I have a project where I wish I had a 220v mig, and will eventually upgrade. If I was buying a unit now, I'd definitely get a bigger one, but I wouldn't have 60% duty cycle in mind still, especially given that I work mostly outside in a cloud of flux smoke, but mostly because I'm not laying down yards of weld, just mostly an inch here half an inch there.

Eric,
Thanks for the tips. I will get a weed burner to pre-heat. So it sounds like dual shield wire is flux cored that is intended to be used with a shielding gas, whereas regular flux cored wire is not meant to be used with gas? Do I have that correct? I’ve put off the heavy projects for fear of not doing a strong enough weld. Was suggested I get a tombstone arc welder for the heavy stuff, but prefer not to go that route yet. Thanks again.

According to the Hobart website, the Handler 210 MVP weighs in at 79 lbs and is a transformer machine. Their closest equivalent IGBT machine weights in at 38 lbs.

I'd be very surprised if the new MVP machines are transformer based in as much as much as all Hobart machines are now made in China and none of the Chinese machines (no matter what brand) are transformer base. All are IGBT based.

Yeah, you have it right about dual shield. I use it sometimes but only when I need to really lay down a lot of metal. And I wouldn't even use it if I hadn't been given a brand new 30 pound spool. I think it's 30 pounds, it's huge and heavy. I use it in my big Miller, which is a 300 amp beast. Anyway, you posted that you have a Miller 211. They are good for welding 3/8 material in one pass. So If you pre-heat you should have no problem getting proper penetration. After you have run a bead or two the metal will be plenty hot. I suggest, for your own peace of mind, that you take a couple pieces of 1/2 material, weld them in a similar manner to what you plan to do for your project, and then put the pieces in a vise and beat the crap out of them until the weld breaks away from the parent metal or your arm gets too tired from whacking away at a weld that's not gonna fail. Then you will know if your welds are adequate. I would not hesitate to weld 1/2 steel with a Miller 211, I would just pre-heat to make sure the penetration is proper.

Think you need to really consider dual purpose machine (GMAW/FCAW) as both have their uses in different ways..... And cost wise, not that much difference.... I been welding with GMAW for about 8 years now and I still have about half of the demo roll of FCAW wire in drawer... If you do get dual application machine it does not mean you have to get solid wire and shield gas immediately but just having the capabilities is a step up....

Hobart makes a really nice dual voltage machine, the HANDLER 210MVP for about $1,150 (SRP) ... Shopping prices vary...

Handler® 210 MVP™ MIG Welder | HobartWelders

A portable MIG welder that has 210 amps of power. Welds up to 3/8", offers dual-input voltage Multi-Voltage Plug (MVP) operating on 115v or 230V and up to 210A output power. Let's start a project together.

I have that exact welder, love it!!

These MVP are left over from the old Miller line. ITW is squeezing as much as they can from these units.

Being in the industry and not on the consumer side, I suspect you know. I do know (because I looked at them) that the current machines for the most part as well as ALL their accessories are made in China and that includes all their self darkening hoods.

Again, your TIG cooler works excellently though I did purchase anti-freeze non conductive coolant from Weldfabulous. The fan is a tad bit loud but I keep the machine and the cooler in an adjacent room from the welding table anyway. I suspect the noisy fan is attributable to the amount of air it moves and the more air flowing through the heat exchanger, the better the heat transfer is. I do know that even when running high amperage when welding aluminum, my CK Series 20 flex head torch never even gets warm enough to be uncomfortable to hold and that is with 20 feet of welding and cooling leads. Excellent cooler at an excellent price point. Again, thanks for the product.

Here's my $0.02....

If you are ok with buying Bullets for China ( and a lot of US machinery is now rebranded Chineseium ) then take a look at the YesWelder brand.

I have the older version of this model, I really recommend that you run it with 240v vs 120v as I kept popping breakers to get enough heat with 120v. But it is possible.

I looked at a lot of name brands and not so name brands and I couldn't beat this machines price vs. performance ratio. Right now about $550. No way does HF even come close, either.

Get the 20' welding gun/cable with the standard consumables - it's extra but so worth it.

I run gas when I can - but did a F350 dump body with brand new steel with flux core for a friend. Just remember to flip polarity when moving between normal wire/gas and flux core.... I was stupid at first and couldn't understand why the thing was laying down streams of fluxcore BBs.... Oops!

I'm also running their 65 amp plasma cutter - works nicely for little $$$.

Good luck, Blake

WRONG in so many ways...

Far as bullets go, I wasn't aware they were made in China. Been reloading for over 15 years and never seen ANY bullets or loaded ammo made in China. Hornady, Grand Island, Nebraska, Federal, same, Berger, Michigan and California, Sierra, St. Joe, Missouri etc. None are Chinese and propellants come from here as well as Australian (no Chineseum)..

I believe you are smoking something or just naive or possibly both

The HF welders are available in your local HF store, they all have a 100% money back guarantee for a year, extendable to 4 years, all come with leads and ground clamp and for just a tad more you can purchase a true multi process welder and they are all IGBT machines.

$599.99 everyday....

Why buy a Chineseum offshore welder that you have to wait for, for possibly a month and if it craps out, what recourse do you have, maybe sending it back at your expense and maybe getting a replacement, maybe, when all you have to do is return it to the LOCAL HF store for a refund or replacement.

You need to practice due diligence before posting something that is patently FALSE. My 2 cents worth, lol
