As above, after doddling along with an old pub gas bottle to learn for the past week on an old welder I've inherited, it ran out (20 year old bottle of my dad's, it's done well!), I was getting results that look at least half decent, with very consistant penetration:
I just got a nice bottle of 5% mix (J & G Gases, cheap as chips!), but I'm really struggling to get the welds as neat, I know it's thrown my settings off so I've been experimenting for 10 minutes with it, but what I think I'm struggling with is the audiable change - I found it pretty easy to judge what the weld was doing with CO2 by tone alone, whereas the smoother hum from the Argon mix is throwing me off.
Does anyone have a video of the exact sound I should be dialing in for on the wire speed (on the 1.2mm sheet I'm practicing on, low enough to prevent excessive penetration is right on the edge of a crackly/inconsistant arc, which I then struggle to be neat with)
I probably just need a few hours practice the same as the CO2 but if someone can help me get dialled in faster it'll save me some gas
The other thing that has become apparent to me, perhaps with the smoother, quieter hum from using argon - I'm guessing it was there before but I didn't hear it - is the machine has a rythmic throb every few seconds, which co-insides with a slight change in the weld - I'm guessing this is probably wear on the feed mechanism, but is there anything else I should I be looking at if not?
On the upside, the spatter has gone!
