SIP Hobby MIG Welder Upgrade to Big Bottle - Flow Rate

[Binney]

Hi,

Recently I was given an SIP MIG Mate welder which uses the small disposable gas bottles. I'm considering upgrading to a large refillable Argon/CO2 mix from my local motor factors and purchasing a regulator to plumb it in to my hobby welder.

I recently brought a basic pea shooter on ebay to check the gas flow using the disposable bottles. With a new (CO2) bottle fitted I only get about 3 l/m, I believe 10 l/m is a good target?

Will a big refillable bottle have more pressure and be able to get a better flow rate?

Thanks in advance,
Binney

Welcome to the forum.

A proper bottle and a decent regulator should be fine. Those disposable bottles and their regulators are a bit hit and miss.

Thanks.

I've been practising on some different thickness metal for a little while now and have finally got to a stage were I can produce welds that aren't too embarrassing. I'll post up a few photos to get some feedback in the beginners section soon.
