End of run

[mrc79]

Hi everyone
I have not been welding long but managed to make a fence in my garden with good results (5mm Steel).
I have a few projects coming up and thought that i should practice my arc welding skills as I was not too happy with the finish of my last project,
(A Welding Table).
I have a Parweld XTI 160 running at 70-75 amps on 3mm steel using esab 2.5mm electrodes.
when i manage to get the speed and angle right I find that as i get to the end of the run / edge of work i have too much heat and am unsure how to finish the weld. i often end up with a hole or flat weld at the end. if I leave the rod there for a few seconds it melts the end of my work.
Any ideas how to end the weld?
Many Thanks, Mike
I've tried to upload photos but could not get it to work.

On the end of a weld, I make sure ar arc length is real short. As soon as the puddle reaches the edge I run the rod back up the weld then break the arc.

If i try and break the arc at the end, it will just melt the end (arc does not stop until I get over an inch away.)

thanks, I will give it a go during the week.

When you're coming to the end of the weld.

It is recommended that you straighten up the rod.

For instance, you are welding along at this angle. /

Right before the end of the weld.

You should straighten up the rod to this angle. l

And also keep a tight arc as already mentioned above.

This will reduce the risk of blowing holes and making a mess.

I generally mig weld but I normally put a tack at the end i'm working towards.

I always get to the end, pause very briefly, move back about 5-10mm and then break the arc sharply.
