I have no argonshield bottle any more, but i have had a pure argon bottle offered to me for nothing. can i use pure argon on steel or is it useless, i have only ever used argonshield and pub gas before on a mig welder. thanks Robbie
If the weld isn't mega critical it will do the job with mild steel. (Meant for stainless/Ali) Penetration may be lost or you may have to adjust your settings to obtain a decent result.
