I've done a bit of 'sticking things together' for a while now - but have never been happy with the tidy-ness of what i'm doing. So i'm trying to start from scratch and get a lot of basic practice in.
My welder is a Sealey Supermig180 - i'm using 0.8 wire and Hobbyweld 15. I'm trying to keep the wire very close and at 90degrees to the surface I want to weld - then pushing the weld, with the gun slightly angled back
If more experienced welders can give some feedback on why I have the results I do it would be much appreciated!
I've started today with some 3mm plate - welding 'straight' beads onto a bit of scrap. The pitted blobs were not todays effort. Here's the first set of runs.
Side on
And the back
This was all on power setting 4 of 6 and fairly slow wire speed (about 3.5 out of 10).
Then I upped the power to 5, and the wire speed to about 4. These were noticeably hotter - the metal all glowing bright red immediately after the weld was laid (heat built up in the plate too!)
And the back
Then I went down to 2mm box - my main aim being to learn how to weld round and square tubing together. I tried some straight runs first and found i had to drop the power to 1 out of 6 and reduce the wire speed.
First I tacked up:
Then I tried to weld in 4 passes.
Thanks in advance!
