Hi Everyone!
I only know about stick welding and right now I have a 200 amp overseas stick welder that dose everything I need it to.

I want to learn how to MIG weld and am starting to look around at a few even though I am almost illiterate when it comes to MIG...

My main question is (1) what is the amp conversion for stick/Mig. - to weld what i need 180 amps on a stick welder do i need 180 amp MIG?

And also \/
(2) I dont have it but in Stick welding there is ARC force to get more penetration if needed - Is there something similer I can look for in a mig welder or is the consept that diffrent that that is not needed?
(3) I dont need a top of the line welder but what are some decent brands besides Hobart and Lincoln?

Any feedback is appreciated,
Thanks - Peter.

Your welding current for MIG is a function of your set voltage vs. wire speed, and "arc force" doesn't apply.

MIG equipment is generally sold based on it's thickness capacity, but beware. A machine that says it can weld 3/8" may only be able to do that for ten minutes at a time. (Duty cycle.)

If you are accustomed to using 180A, that equates to some heavy rod. I rarely burn a 5/32 7018 above 150. I'd look at the Miller 250/251/252 series for their specifications, and use that for the basis for a machine. (If you have the coin, that Miller is a GREAT machine. If not, it's specifications will get you in the ballpark for the current you want to weld at.)

thanks for the reply.

Looked at the Miler 252 and the Hobart and Lincoln equivilent and I need to get some more cash it looks like

I looked on Ebay and 250-300 amp Migs are around $1,400 - $1,800 so I might be able to get one in 2-3 months...

Thanks for the feedback

How thick of metal are you planning to weld? 180 amps is really high for stick, but I have found that amp settings can be subjective according to the shop/power supply/welder that you are working with. I would recommend something like the Millermatic 212 or something similar from one of the other major companies unless you have needs beyond their capabilities. I have used a combination of mig and stick on many projects over the years. Stick on the thicker sections and mig on everything else. I guess it all depends on your needs.

I bought a used Millermatic 210 for $1200 on consignment in a Welding shop.
Then, a week later I found a second one for $40 from the scrap recyclers. (for spare parts)

Miller makes great machines, so if you can get one, you won't go wrong.
(BTW - Hobart makes a similar product, as both companies are owned by ITW.)

Hi again,
Dose anyone have any thoughts on the fabricator 252i 3 in 1 welder?

I use 180 - 190 amps for 6010/7018 4mm thick.
+ I am working off of 110 volt most of the time soooooo....(stick welder is a 110/220 optional and cant always have 220)

I have a problem with those numbers. 6.35 mm = 1/4", which calls for, at most a 1/8" (3.175 mm) rod. In 6010, I'd be at 105A MAXIMUM, and 7018 120A MAXIMUM.

Your machine is either misleading you, or is AC only, or is malfunctioning. I do this professionally,and have for many companies, with their equipment. Never the same machine twice, and strict QC. 180A would blow holes in 4mm with most machines I've used.

The recomended Amps is 120 - 160 for the sticks and since I am on 110 most of the time and my machine is not quality I weld at 180 amps A/C and no there are no Wooshing sounds or excesive splatter.
If i remember right I use around 120 amps for 3MM witch is at the top of the 80-120 amp range on the packet.

These are the numbers I have and the welder I know in RL on his machine uses 180 amps for 4mm and he has been welding for 30 years...
btw the rods/Sticks are 4mm thick-actual metal is 1/2 inch if maybe you read it wrong.

First off do you need dual voltage or one that will only work on either 110 or 220..

I recently purchased the Millermatic 212 with Autoset and the Spoolmate 200 spool gun. Should cover anything I really need to ever weld.. But it's a solid 220 only machine. I looked into going with the 211 with it's MVP (Multi-Volt plug) but I didn't like the duty cycles compared to the dedicated 220 machine. but the 211 will weld thick (3/8') steel, just at a short duty cycle on 220v..

What about the Multimatic 200 multiprocess welder. Mig/Tig/stick.. ?? under 2k with the optional tig kit.

Yes, I misread. With the rods at 4mm, those amps make much more sense.

6010/7018 are DC rods (DCEP), so 180 on AC makes more sense, as well. For AC use, 6011 will give better results, and there is a rod called "7018AC", the difference being primarily in the flux for both.

The SAE equivalent for 4mm would be 5/32", which I use 140-150A for on DC.

I weld in the Dairy and Machine barn in diffrent places so if I had to I could wire in 1 or 2 more 220 plugins.

It looks like I am going to buy a used welder just because the new ones are alot of money
miler 200 multi process welder/generator is around $800-$1,400 so a bit better then the $2,200 new price tag...

Sorry for the misunderstanding Steve - Ill post it diffrent next time.
