thanks graeme ,
my intentions are to weld 2.0mm & 1.6mm

i was thinking to w i a 13s electrode 2.0mm ,,but not sure

Hi
I can only recommend against vertical up welding in that thickness as it will burn clean through a 1.6 to 2mm wall thickness.
Why does the work need a vertical up weld? Can it be manipulated around? A vertical down or even a horizontal vertical weld bead if the job can be turned will be as strong as those weld position can offer adequate penetration ( strength).
It certainly not something I would consider tackling with this process (stick) and certainly not with a transformer welder.

Nothing wrong with your machine per se, but the transformer type of arc ignites the rod with a (the only description I can think that is anywhere near close, is a) bang.
This of course with blow a big hole in a job that light.
I am not even sure I could do it with the Hi tech Fronius. I know I would be placing a block of copper or aluminium on the back side of the sheet as a heat sink to soak up the extra heat.
A picture or a diagram will give us all a better chance of assisting you.

hi ,
the job is outdoors ( fence work ) anyway,, i may have to use a mig
please note i,m only a novice welder
i thought i might try my luck as arc welding as its more of a challenge
have practised v up on thicker material ,,,works for me however
v down was a disaster
never mind i.ll go mig

thanks

I have down them downhand with a transformer but in thicker walled stuff.
I have a post somewhere that has the diagram and the angle used its steep and yes requires practice.

If its fenccing its harder if its gal and will most certainly be that.Knock of the gal first.

I shall post more tommorrow .Had a big day.today,i am knackered.

You mention outdoor fencing.
If it is galvanized steel I would recommend some scuba gear! You really don't want to inhale burning zinc.
You will also want a rod where the third # is 1 . Example 6010 or 7018 . You would not use, for example 7024 as this would not be an all position rod.
Hope this helped.

thanks mate
dont need scuba gear as its windy most times ,,which is a bonus (next to lakes)
i.ll see how i go & will let you know with photos

cheers
