Ozito MIG welder upgrade Europlug

Hello
I've had this Ozito Gas / Gasless MIG welder for 8 about years now and it's not running like it use to. It constantly spits and splatters whilst welding and can't produce a good looking weld despite my best efforts.

So I decided to dive into upgrading the Mig Gun, Earth Clamp and conection stype to an international standard Euro Plug.

Please be careful when modifying welders, they can produce harmful high voltage and or high current which can be fatal if proper procautions are not taken. If you are a novice with electronics - for your own safety please do not attempt this upgrade without seeking profesional guidance.

Very cool upgrade. Well done. I have an ozito Mwr 090. Still going strong after maybe ten years..great little welders.

Good job, not a bad welder for learning to weld, although duty cycle I find isn’t that good with thicker material. Went to Unimig and never looked back.

Great little upgrade mate, now it's like a new machine and very user friendly. Plenty of welding videos to come I'm sure.

Excellent video. I have a Cigweld 135 mig with an attached 3 metre torch and it drives me crazy! Adding the Euro fitting looks fairly straightforward. But unfortunately the Cigweld 135 also must have the cheapie gas solenoid inside the torch. I looked for a solenoid inside the welder, but no dice. After closely looking at your Ozito, I think they are the exact same machine, just a different colour and different badge. Everything else looks identical.

Hey mate, great video. Buddy of mine upgraded and gave me his one of these. If i was just going to run it gasless i wouldn't have to add in the gas solenoid etc?
Ground cable on this one is all chewed up so have to replace it. Might as well make them longer and detachable if I can.

Another upgrade would be to make a cart to hold the machine & gas cylinder 😎

the patch leads you made what size conectors did you use inside hole size and what ohm was the 5w current limiting resistors thank you

Sweet upgrade! Wonder if it’s as easy on the Michigan from

Hey great video . May I ask what did you find wrong about the machine earlier in the video you said your machine not welding properly and when you found out why it isn't you show some connections to be I presumed wrong. Can I ask if you can further explained what was that you found wrong. Thank you

I Changed one over to Gas and Used a LPG Car Gas Valve $12 .

Sir, I have the same welding machine (Ozito MWR-135). Recently my selector switch got stuck (jammed) and I tried to repair it but I failed. Now I am not in a position to operate it. I just can not find a selector switch of that type. So I thought of connecting two toggle switches to select the current.
Could you help me to connect the 4 transformer tapings by a small diagram?

Do they have detachable ports for flux core mig wire ie no gas?

[timmcnamara]

Can you connect a euro TIG rig and see if it would work?
