Gauges and settings

[Mark S]

Hi all
Can anyone tell/recomend to me which gauges I need for my Sealey 150 mig.
And the general setting for the gas mainly using 3 - 5 mm plate, trying to patch up my Land Rover 110.

Tell us what gas are you using. Is it co2 or argoshield and is it disposables or bog bottles? The regs are different for each bottle and different again for the disposables.

i use co2, its cheaper than a argon/co2 mix. also it depends what your going to weld too. just re read your post. are you welding up the chasey? id use co2/argo, have a look in weldequips shop, im sure theres some regs there for co2/ argo. are you going to be welding outside or inside? also as clemdog has mensioned, are you using dis bottles. cheers

Thanks for the replies
I am using co2 from a rental bottle (its about 2 feet tall).
What would be the advantage of using co2/argo mix?
I work both inside and out, but only if the weather allows.
Its only hobby work on the Land Rovers.

Anyone
What would be the advantage of using co2/argo?
At what setting should I use for chassis 5mm approx and inner guard 3mm approx material.
I realised a while ago when welding good clean metal leaves a better weld.
Is there a rule of thumb for different metal thickness and metals them selves?

 

[Mark S]

Any chance somone could give me an answer.
Please.

Ar/CO2 is cleaner (less spatter) than CO2. It is also easier on thin metal as the penetration is narrower.

Start with 10LPM gas flow. Usually does not need to be changed.

Thank you very much for the reply.

As Scott says usually once you have gas flow set it does not need changed.

Too much flow can cause problems as it can create a tornado effect effectively drawing air into the weld pool.

Disconnect the wire feed and hold the torch to your ear and pull the trigger. The gas should be audible as a dull hiss.

Cheers clem dog.

Thats sorta what I have been doing, but I thought the gauges might help. I will take any advise given.
It's the upside down welding and rusty metal on my Land Rover that causes the most problems.
I like to have a light on the work piece that I am welding.

if you are using a pub bottle or a boc type rental bottle you can get a reg with two clocks, one for cylinder pressure and one for flow rate.
The argon mix bottles have a different fitting from the co2 bottles, but you can get an adapter to allow the argon reg to fit a co2 bottle but not the other way around.
Straight co2 has a liquid pressue of around 80 bar iirc but argon mixes have a fill pressure of up tm 300 bar so the respective gauges reflect this.
You should be fit to get either reg from weldequipe or on ebay for around 30 quid or call into modern machine services in lissue ind estate in lisburn. They can be quite good tm deal with

Guage or Ear ?

I have been hobby welding for about 25 years working with the same old kit - a sealey 160 welder bought secondhand together with regulator with single (input) dial.

Always judged gas output flow by ear as too much gas is a waste - too little produces the obvious porous weld. I found that as the input pressure falls, particularly when bottles are on their last legs, the output pressure drops and needs adjusting.

Thanks for the pointers guys. I think I will get a set of the double gauges had a look on the net but I might try that place in Lisburn. They may not make me a better welder but at least the gauges will look good.
