Using c02 for mig welding.
Got a 150 amp mig welder to sort my car out. It's come with a disposible bottle of c02. I've tried it out but seems to splatter a lot guessing it's due to the c02? I've tried playing with the settings. If it's on two it's blows holes through. Is argon only meant for aluminium?
Only Use an argon/co2 mix for a proper weld! Co2 is shite for mig it's a cheapskate way of welding. It will give spatter as you say also poor penetration . Co2 cools the weld making poor welds. You need an argon co2 mix and the small hobby bottles are bollocks! I will suggest this but might break your pocket but when you weigh it up it's sensible! Google sgs gas and search your nearest supplier. I have 2 local suppliers one said £130 deposit for a 20litre bottle the other said £90 for deposit and both said £70 for the gas. It's a rent free bottle so keep it as long as you want. I have just fabricated a 16 metre railing with a 20 litre bottle and used only a quarter of gas. These bottles last a long time compared to the stupid hobby ones! Set your gas at 10 litres per minute on your gauge and you will see. If you purchase a sgs gas bottle get on the mig welding forum for the £20 cashback deal as I did! So my initial payment was £160 but £20 back so £140 and I still have £90 deposit I can get back! (I won't do that as I will always need gas)
I am a fabricator welder by trade so I know my shit! But Andy might correct me
Thought so cheers for the advice will Google it and see. Like you say they are never going to last as long and have a fair bit of welding to sort.
Here's the link to sgs gases and you should find a distributor near you http://www.sgsgases.co.uk/
Cheers .
Also here's the other offer you can have if you want a rented bottle though the mig welding forum http://www.mig-welding.co.uk/forum/t...-offers.40809/
I hope me posting this doesn't upset the mods? I'm only want help others with welding. As welding nova's is a big part of keeping them on the road.
Pure argon is for various tig welding.
