1mm will carry more amps. Give it a go and compare two samples, always best way to find out.Thanks for all the tips! Im using .8mm wire; should I try 1mm for this? Will be doing some railings so 16mm round bar to 10mm flat rail shortly (hopefully)...
so will give it a go again
Your as puerile as me my first thoughts was to try viagraWish I could be saying the same, regarding the title.
To add to Roberts post above, you also need to be careful of travel speed. If you are going to slow then the wire will be burning off back in the puddle and not pushing into the root on the front edge of the puddle. Try the same settings with correct torch angle as above but increase your travel speed x2 then do another macro and compare.
neither of these things will improve penetration!Reduce wire feed speed
Increase volts
There is too much weld metal which has an effect on the amount of fusion
From travelling too slow, sureThere is too much weld metal which has an effect on the amount of fusion
Just goes to show there are probably more than one way to skin a cat, provided the wire feed speed was high enough I would turn the volts up and get it into spray transfer, plenty of fusion and no spatterFrom travelling too slow, sure
Lower the wirespeed equals less amps = even less penetration (can you get less than zero?!)
Upping the voltage won't improve anything, it'll just create spatter.
