Hi chaps, I have had a Clarke 151en for a couple of years now, done the odd bit of welding here and there but nothing structural I’m talking, putting fishing hooks onto the end of poles to use as gaffs, the odd bracket here and there to hold tools in my workshop, I had the idea of welding a mini once but that fell through. I have recently purchased a cheap Land Rover defender, a couple of areas in the chassis needs patching but it needs a rear crossmember, having done research the metal it is made out of is 2mm-3mm anyways I had a couple of steel brackets I found and thought I would run some beads..... these are my first proper beads since getting the welder, however I am seriously having trouble with penetration, I can seem to run ok ish amateur beads (probably not when you see lol) but from the space of one second I seem to get no penetration to blow through, I numbered these beads but unfortunately I didnt write down which wire settings were which, the Clarke 151en was on max settings all the time shifting between 7-8 wire speed, maybe the welder just struggles to comfortably do 3mm?? Anyways the main area I need to do on the Land Rover is a rear chassis, the type that fits over then you do a “lap joint”??? Not sure if that’s the term but basically the box section of the chassis goes over the original and you weld it, I really want to weld the chassis myself but I’m not sure where to go from here, it literally seemed to go from one second longer on the bead and blow through or keep travelling and then not much penetration on the other side. Number 9 is a buttweld, which for the chassis patches I’ll be doing as well.. Cheers for the help in advance and thanks for any advice!!
