Convert Flux Core Mig Welder to Gas For Cheap

[@konquer247]

Great work, definitely will give it a try. One thing you need to bear in mind though, is you need to change the weld wire to the un-shielded one.

[@obfuscated3090]

Useful video. The "nozzles" are called "hose barbs" and available in various male threads and barb (the part you insert in the hose) outside diameters.

[@083rt]

Ob Fuscated thanks for this info.

[@bdidksghskskss]

My welder doesn't have that nozzle on the wore feeder any idea where I can get the wire feeder with a nozzle in the video

[@eardleyham3734]

Your solenoid has two (probably tapped) mounting holes. Why did you not use them for a much more rigid and safe mounting?

[@Chris530-65]

Great detail I was just getting ready to see what I needed to convert to gas so I can weld sheet metal better. Thanks

[@danburch9989]

Excellent conversion. The only thing I would suggest is when passing tubing through sheet metal, drill the hole larger and instll a rubber grommet. It will better protect the tubing. I find it hard to believe the valve has to be mounted with wire. Are the two holes at the bottom of the valve threaded? I can't tell from the video and it doesn't look like any screws in there are holding the solenoid together.

[@watcherwatchmen7785]

Argon and c02 aren't volatile gasses, so even if it wears through, you won't have to worry about anything dangerous.

[@fastal48]

Thanks for the straightforward well done video.

[@bobthorman64]

Hey thanks for making this video. I found it very helpful.

[@davidstemen3944]

The 220 volt gas solenoid . What size lincoln weld pack will it work on ? I got the 155 wondering if its compatible with this welder thank you ?

[@sudinakok9235]

where did your wire the solenoid to?

[@nexromancer]

I know this is old but from the solenoid to the marching. Is the brass valve a 1/4 male x 1/4 hose barb or is it 1/4 male to 1/8 hose barb. I was looking at the hose fitting on the machine and it looks like it’s 1/8. I don’t was to use the wrong hose and hose barb and have gas leaking on the gas input on the machine.

[@ThaMazda]

What size hoses did you use?

[@Chris530-65]

I know this video is old but I have same welder and it’s 110 volt does the 220 solenoid need to be 110 as well?

[@Flightsimclub]

Nice video. But why didn’t you just mount the solenoid through the hole on the back side of the welder? Instead of running the hose through.

[@NOWAN1980]

Great conversion, which is the soleniod size, is it a 1/4 inches type? Thanks!

[@Comm0ut]

If you have multiple welding machines you can plumb a 5/8-18 RH x 1/4 Male to the back of the welder to use standard welding gas hose and fittings. A bulkhead connector or other strain relief will protect your solenoid valve. It's only plumbing so whatever fits and works safely is fine. The Weldingweb forums have many posts on small welder conversions and are noob friendly. While MIG mix welds with less spatter these feeble little machines weld better on thicker stock using CO2 whose cylinders also last much longer because CO2 stores as a liquid while MIG mix stores as a gas. Best to have both so I do. The small "kegerator" size CO2 cylinders are nice for mobile work.

[@esqueue]

Tape on your regulator is a bad idea. The threads do ZERO sealing. The only sealing is on the face of the fitting. Good idea though about just making my own kit instead of purchasing one. In my case, I may go with a 120v solenoid as that is what I'm running on.

[@jet6374]

he obviously has no clue what Teflon tape is intended for.

[@danielhutchinson8377]

Great video but didn't show where he wired the solenoid

[@CPUDOCTHE1]

You don't need tape on the threads on the regulator where it threads into the tank. The threads DON"T seal.

[@kirkearl]

CPUDOCTHE1 good to know. Does it need to be removed or no problem?

[@jonathanbarclay4584]

The bottle and regulater are self sealing they are ment for each other.

[@watcherwatchmen7785]

@@kirkearl If it was oxygen, YES you would have a hazard with that setup but since you're using argon/co2 they are inert gasses, so you're ok. I'd remove the tape anyways though.

[@JuniperSystemsInc]

@@watcherwatchmen7785 Thanks. I've learned a lot since making the video. I was afraid at first the gas was a ticking time bomb, but I've since learned the difference. I've taken the tape out of there too. This set up has been working great for a few years now.

[@hughobrien4139]

If those fittings are not sealing up and they’re allowing gas to escape usage then there is nothing wrong with using some Teflon tape to seal it up. People use tape for inappropriate reasons all the time. Not everyone has the means to run out and buy a new regulator and they’re not filling gas bottles for free anywhere. So screw the tape pundents and use tape if that’s what seals up a leak. Unless they want to buy your gas for you in leu of your roll of Teflon tape, then you shouldn’t listen to a word. Half these bottles are never checked for damage at their sealing points in the first place.

[@path5020]

Nice job - do you by chance know the part number for the 220V solenoid?

[@kirkearl]

I bought this one on ebay: EHCOTECH B20V-1/4-CD-220VAC SOLENOID VALVE

[@calel5196]

They seem common I have seen very similar ones used for firetruck deluge systems. Those were designed for water of course.

[@jacob.jacob.5003]

Muchas Gracias Amigo.👍. I knew i was doing something wrong..polarity was switch.now works good.TY .

[@ecrusch]

That was really helpful. Thanks a bunch !

[@velo-br2he]

Excellent job! Use the bottom of the solenoid to screw it into the welding machine.

[@mauromartinezperez4871]

Could you please describe the parts we need in the coments

[@madfriday67]

What shield gas are you using.. Is that Co2..?

[@watcherwatchmen7785]

Usually a argon and co2 mix of 75/25 for welding mild carbon steel.

[@ckproper]

Where did you buy the gas?

[@johnnywrench9669]

Great video buddy.

[@Z32orDIe]

This was excellent. Thank you!!

[@glevesque5295]

Hi. Can you give us the link to buy that solenoid and it's part # ? That would be very appreciated. Thank you. And let say that Lincoln electric did a shitty job for that gas conversion. They could have done a lot better. Thanks for your video !

[@CPUDOCTHE1]

You don't need tape on the threads on the regulator where it threads into the hose barb. The threads DON"T seal.t

[@watcherwatchmen7785]

Correct. If you have a leak coming from that junction, it will be because the seat or surface is nicked or damaged. Sometimes they can be dressed up with a fine stone and a magnifying glass to get rid of the burr.But for safety, I'd always recommend just replacing the damaged part.

[@willwills100]

Don't use tape on the treads going to the bottle or the hose barb it don't need it it has flare fittings also on the inside it has 2 holes right under the plugs just drill one hole and you can screw right in the back of the selanod

[@jw200]

I have cheap HF AC 100A welder, it doesnt support gas. On ebay i found a kit with mig gun with euro connector , socket and gas solenoid. "Mig Welding Euro Torch Conversion & MB15 EuroTorch 4Mt + Inst & Gas Solenoid E79" Its easy to convert this welder to DC (rectifier 150A + big capacitor) and then install the kit, do some wiring, add transformer for solenoid and relay and basically you have mig welder with gas support. I even had idea to make my own new gun so i can add gas hose to it etc. It will be a bit cheaper. just buy a gas solenoid. I have everything else. but i dunno yet. maybe its easier to buy gun that supports all this already Kit itself is 100€ including shipping. With small cylinder of gas and reductor the total price will be around 200€, still 100€ cheaper than buying cheapest gas ready machine. i bought the welder from ebay for 80€ electrics and electronics is my hobby, so wiring is not a problem this is my plan and im gonna try it.

[@obfuscated3090]

If it's pure AC you would benefit from adding a rectifier.

[@083rt]

jw200 you should make a video

[@davidwillis5016]

Thanks

[@XPFTP]

NEVER PUT TAPE ON UR BOTTLE... ask a welding supply what to use on the rest of it.. tape isnt good .. i wouldnt use it.. i heard somewhere it reacts with some of the fuels used.. but for sure NEVER USE ON BOTTLE SIDE...

[@kirkearl]

XPFTP noted

[@Richardson501]

Big patch of good quality velcro would have worked also 🙃

[@shaunpilkington4625]

Does this actually work? I’ve had a fluxcore welder for years and never used it because it’s crap

[@kirkearl]

If your flux core welder is one that can be converted to a gas welder this works. You are basically just making a homemade version of the conversion kit that your welder brand already sells.

[@josephgonzales3573]

Flux core is NOT Crap. Maybe it's just your crappy welder

[@brianwasmund7568]

@@josephgonzales3573 90% of Flux core welds ARE CRAP! Unless you are running dual shield.

[@MRKTM690smc]

I'm so doing this. I've used a flux core for 5 yrs and have not wanted to use gas because of the way I was storing my welder. I finally bought a small cart and have room to use gas....

[@jet6374]

WHAT GOOD IS THIS VIDEO IF ITS FOR "ALL THE WELDERS THAT ALLOW FOR EASY CONVERSION"? what if I dont have "THAT NOZZLE" ????????? Right here on the circuit board there are 2 PRONG THINGIES???? prong thingies? Really?

[@kirkearl]

Jet it shows you how to not buy the manufacturers expensive conversion kit and create your own cheaply. If you don’t have a welder meant to be converted it won’t work. Sorry it wasn’t more helpful.

[@godsmessanger3117]

Yea like you really need to be doing video and be doing it Wrong . You need flask reg with ball in it to adjust the gas otherwise you wasting gas

[@kirkearl]

It's been working great for a few years now. Haven't noticed any excessive gas consumption, but maybe. I'll look into a flask regulator though. Thanks for the tip.
