picked up my new (secondhand) mig last night, a Clarke 130en. It came with a reg. see pic. Can i use this with refillable argon and argon mix bottles ?
That one can only be used with refillable bottles. The one for disposable bottles is different and smaller and disposable bottles are only worth will if you are only going to do about 2 small jobs each year.
However looking at the "Oxygen" label I'm not sure if it will fit an argon bottle.
It looks like it has the right fitment for Argon/argonmix cylinders and the hose and flowmeter show it has been used on one so yes, it will work.
It has '300 bar service' written on it which means it can handle the pressure ok but I'm not sure if there's a downside or even a safety issue regarding using it.
As a general rule of thumb it's always best to use the correct regulator for the type of gas you're using.
As i will be using argon and argon mix do i need a different reg for each (sorry i`m still getting to grips with this) just answered that myself by reading the weldequip shop site
