Hi again.
My technique has improved on the thin (0.9mm) bicycle tubes that I started working on, but now I've gotta weld some 3mm to a piece of thick walled (2+mm) tube, and I'm worried that I may not get enough penetration for full strength as it's a suspension/steering member.
The welder's a Telwin, and I've been using it on 'minimum' with 0.6mm mild steel wire and as slow a wire feed speed as I can get away with. Can I use the same wire for the thicker material, and flick it up to 'maximum' (crude? you bet!) and get more penetration by upping the wire speed to compensate for the higher current? Or should I bite a bullet and buy a spool of 0.8 wire and some tips?
Thanks for sharing your thoughts.
cheers
