I'm practicing my mig'ing on thin sheet in advance of a fair bit of work
on a mini. I want what I do to be neat and strong.
My horitontal welding is getting better, the welds are neater and seem to
have about the right amount of penetration. (I found reducing the wire
feed and holding the nozzle nearer the weld helped a lot).
I will have a reasonable amount of 'vertical' welding to do, running welds
horizontally and vertically on vertical panels. To date I've only tried
quick experimental runs vertically and they have all ended in disaster.
When running a horizontal weld things will tend to droop so I presume the
torch should be aimed upwards slightly.
Should vertical runs start at the top and move down or vice versa?
Am I going to end up doing the whole things with pulse welds?
Does anyone have any recommendations?
Thanks in advance,
Nial.
