I would be really grateful if you could offer a little advice im having a few problems.
Clarke 160amp MMA welder
6013 2.5mm rods
40x40 RHS 2.5mm thick
25x25 RHS 2.5mm thick
fillet welds(?)
I am working on a gate, the 40mm is the frame and the 25mm bars are the uprights.
The problem is inclusions, i have become able to weld butt joints nicely but fillet welds the weld will stray to one side of the joint and i keep having to grind them out. I believe i am using the rod at the correct angles, its become frustrating.
Thank you and regards.
(I saw you were from yorkshire too)

You need to be welding at around 90-100 amps. I would probably be around 100-110 amps, but might be a bit high if your just starting out, and need to move the rod a bit slower.
It might help to position the joint as a 'V' - i.e tipped so you are welding vertically down in the V, so you don't need to worry about the weld sagging down from the vertical face onto the horizontal face.
A slight weave of the rod whilst you are welding may also help to spread the weld metal across the joint.
Which make of rods are you using? cheap rods won't make things like that easy, branded rods, even branded white box should be fine..Murex, Bohler, Esab, Oerlikon etc.
I had the same problem with fillet welds when i first started. Post a couple of pictures if you can, always helps to get a feel for the problem.
