Hi All,
like DamienS I'm embarking on a small welding project & have gone through a box of rods over the past week practicing on scrap. I'm using 2.5mm SHS mild steel and have found the info on this forum very educational. I've got a GMC arc welding machine & am finding it well up to the task of joining this metal stuff together. I've stopped blowing holes in my "T" joints by using the technique illustrated by Grahame - so thanks for that!! I'm finding that the key to success is to use amps in the lower recommended range for this type of joint (60A) and to crank the amps up to the higher end of range (85A) for the fillet weld around the corner of the flat joint. I'm using 2.5mm rods. I hope I'm on the right track - my welds are getting a lot neater.
I think Grahame has his hands full ATM with all that rain up in Mackay but just want to thank him & all for their contribution to this forum - back to practice
