Les Henson Posted June 6, 2007 Share Posted June 6, 2007 What's the difference between using argon over argoshield, do you get a better weld or something? Les. Quote Link to comment Share on other sites More sharing options...
bishbosh Posted June 6, 2007 Share Posted June 6, 2007 A grown up once told me that Argosdhield has CO2 in it so you'll get more penetration. The amout of CO2 increases from light through universal to heavy, at least, I think that's what he said! I suppose Argoshield sits in the middle of the range with Argon at one end and pure CO2 at the other? Quote Link to comment Share on other sites More sharing options...
Mark Posted June 6, 2007 Share Posted June 6, 2007 FWIW and I am not an expert, this is how I understand it... 100% Argon is used for welding stainless and aluminium. it is a true inert gas so you are doing tru MIG welding. Argoshield is CO2 with between 5% and 15% Argon in depending on the grade (light (5-6%ish) / medium (10-12%ish) / heavy (15-18%ish). By using CO2 rather than Argon, you are using an Active gas (so are in fact MAG welding) but the CO2 provides an active shield and allows more penetration. Pub gas is 100% CO2 but is usually a much lower grade gas and has much more moisture dissolved in it, so dosn't give the cleanest of welds. As I said, this is not accurate in any way, but I work on the fact that you use Argoshield for Mild Steel, and Argon for Ally or Stainless (obviously with the correct filler wire). I use Argoshield Medium... Mark Quote Link to comment Share on other sites More sharing options...

LandyManLuke Posted June 6, 2007 Share Posted June 6, 2007 Argoshield is a trade name, other suppliers do an Argon/CO2 mix, sometimes with a few % of nitrogen too. Most suppliers have the same range, light through to heavy, with a 'universal' (usually the one available in smaller sizes) thrown in the mix too.

LandyManLuke Posted June 6, 2007 Share Posted June 6, 2007 It's a very useful site indeed, lots of information on welders/welding/MIG/MAG/TIG/gas etc. Quote Link to comment Share on other sites More sharing options...
mike4444244 Posted June 6, 2007 Share Posted June 6, 2007 Hi Les Argoshield is from boc theres a whole page of info here http://www.bocindustrial.co.uk/product_inf.../argoshield.asp basically from what i gather they fiddle with the gas composition to change the welding characteristics, I personally use argoshield universal, i find it welds nicely on most thicknesses of m steel.

nas90 Posted June 6, 2007 Share Posted June 6, 2007 What's the difference between using argon over argoshield, do you get a better weld or something?Les. Argoshield or a mix of argon + CO2 for Mig welding Pure Argon for Tig welding Pure Argon not suitable for Mig Quote Link to comment Share on other sites More sharing options...
Hybrid_From_Hell Posted June 6, 2007 Share Posted June 6, 2007 Argoshield or a mix of argon + CO2 for Mig weldingPure Argon for Tig welding Pure Argon not suitable for Mig As he says above I know as I ran out of Argosheild Light (MIG) and tried using argon (Pure) make the weld feel "Hotter" and easier to pop a hole Argosheild Light for MIG Nige Quote Link to comment Share on other sites More sharing options...
LandyManLuke Posted June 6, 2007 Share Posted June 6, 2007 Or Universal, or Heavy, depending on the metal thickness... Quote Link to comment Share on other sites More sharing options...
smo Posted June 6, 2007 Share Posted June 6, 2007 Argoshield also have a small percentage of Oxygen (3% or so) along with the Argon and CO2, personally i use argoshield light for my mig welding Quote Link to comment Share on other sites More sharing options...
s2hotdog Posted June 7, 2007 Share Posted June 7, 2007 Or Universal, or Heavy, depending on the metal thickness... What he said I use universal at home but could use light - We use heavy at work for structural work Cheers Steve Quote Link to comment Share on other sites More sharing options...
