I saw that, it’s always a little daunting on modern thin, and galvanised, steel. As an apprentice we were taught welding basics, I was rubbish at oxy-acetylene and okay at gas/mig. I have to say much better at stick welding but this is for much thicker steel which, as a farmer, is generally where my stick welding comes in.
I have an old Cebora gas mig that has served me well, it has had new bits put on it, torch and lead. Unfortunately the wire feed went and is no longer supplied, the ‘formulaic’ pattern part gave up within three months, so the welders now a paperweight.
I now have a cheapish gasless and have to say, it’s not bad…just need to practice on a sacrificial piece before getting stuck into the job to get settings right.
