Converting a Flux Welder into a MIG Welder

In this video I go into detail how I converted a cheap flux core welder into a full MIG welder. I bought a broken MIG welder and used the parts from it to convert my Titanium 125 to accept shielding gas.

If you want to do this conversion yourself you will need a 24 volt gas solenoid and a 12 volt relay module. If you do a similar swap with a different welding machine you may need to use a different solenoid or relay, I have no control over this situation. I used 1/4" automotive air line to run the gas from the solenoid to the gas cup, and I did have to swap the polarity from DCEN in order to get this welder to work properly. I'm running 75/25 Argon/CO2, this thing does weld quite well now that I got it dialed in.

This video really is for entertainment only. This swap does not make any sense to do. If you aren't an experienced electro-mechanical technician I can't recommend you attempt this job, especially because it could do harm to you or your property if you do it wrong. Even if you are experienced in this type of thing, I still don't recommend it.

I really like your honesty as to thye value of the value of the viewing person doing this project. I enjoyed seeing how you went about it.

I bought this flux welder and did the same conversion. Alot of ppl say why not just spend 250$ on a Hobart 140 but ppl dont realize this welder is super light weight to do small mobile welding. Hobart and other mig are heavier than this Titanium

[ZeroBaller]

Well that’s was terrific to watch my dude!! Keep on stranging on

Harbor freight should sell a plug and play mig ready gun for this in case anyone wants to do the conversion.

You could probably get the same effect with a setup similar to how a tig welding torch with the valve works. Gas line with a valve spliced in, close to the torch end. And the same way that you supplied the gas to this gun. For someone who doesnt want to go through the hassle of getting electrical with it. Just dont forget your gas on ;p.

Ha, well done. Had to laugh when I saw that piece of weld in your hand, never seen that before. 👍😊

Doctor Who and all those other scifi guys always fixed things by reversing the polarity.

Love me a nice Frankenstein project. Brilliant!

Have you tried to do stick with the titanium 125?

[scottb]

Have you had any problems with welding dcep with the titanium. I'm thinking about doing a dense connectors so I can scratch rig and stick weld? Any suggestions. Btw I love the titanium 125. I'm disabled and the weight is perfect

[kambo]

Can you try welding aluminum with it now?

[RussellHoughton]

I have parts on the was to do this same mode to mine but I'm hoping to power the valve off the wire feed motor.

I bought a weld pak125 hd does anyone know if the wiring works or how to make it run a solenoid like this.

[chrismitchell]

The flux in the flux core wire puts out a lot of CO2 which makes a hotter and deeper penetrating arc. Thereby, enabling the 125’s good flux core performance. Try again with straight CO2! Lol

[TrueSeek-mb]

Did you switch to MiG gas only wire? Regular flux core wire will not work with 75/25 gas mix.

I just wanted to see if you could hook up a longer 15ft mig gun, idc about gas.

[lonniehand]

first good video it keeps people on to the end .2nd I have to know where did u get the bender from Futurama i went to your vids and figured out I don't have one of those so I will have to live with not having one

[MartiArtisan]

Do you think this welder can handle 1/4"? I know that it isn't rated for that originally

[chrismcallister]

So you ran low voltage (heat) and maxed the wire speed. The machine is done voltage (A-G) wire speed (1-10) interesting video but I'd like to convert it to euro so I can get quick connect leads. BTW, typically migs run hotter due to the gas. So running it as a mig, the low voltage you were using it on was probably close to mid voltage in the dcen usage. By the way, I'm a hobbyist using a titanium easy flux welder, and also a professional welder in a factory using a Miller mig that is water cooled.
