well, had a go at arc welding over weekend
setup in garage
cold starting an arc is soo tricky cos it keeps sticking but once the tips warmed up its abit easier to start.
tried the match striking technique and the rapid poking and found that if i'm too gentle n cautious it will stick. but it i just go for it n keep it moving it behaves.
when the surface is bare metal it's really quiet, just high pitch squeeeeeee. tis only on dirty metal like the dustbin or on high amps that it spatters.
first attempts abit meh
on a thicker brake disc i forgot to turn the amps up hence no penetration and just globs up on the shiny disc (like trying to solder on dirty surface). wacked up amps for 2.5mm+ lotsa sparks and stick consuming rapidly but now there's nice penetration (at top)
2nd try at thin panels and doin nothing but burn holes mostly. but found that if i keep the molton pool going side to side at 10mm rather than keeping a steady line, its less likely to burn through, although with less weld buildup
need alot! more practice
think maybe i should get exhaust shop to weld the wideband bung onto me SS pipe (only one chance with SS pipe whereas i'll prob just burn through it), and i weld a bung on the steel turbo inlet pipe for the recirc valve.

this morning i had a meeting in sheffield so the office had already got my tickets for 9am train from middlesbrough to arrive at 11am (originally wanted to drive there in my car but meh, work policy) and my other colleage would join me at yarm station.
set off towards work abit early in hope to park at the office and walk to the station but of all days, tday every traffic light was red and all drivers & lorries were slow GRRR
after parking, i only had 8mins to run across town to the station, omg i'm soooooo un-fit. got to station breathless n wrecked only to find the train was on the opposite platform and left FFS!
thought there was no point waiting for next train cos i'll prob be late. so rang office for the meetings postcode, ran back to the car and set off racing towards sheffield for 11am in a sort of car-vs-train topgear challenge
coughing from exhaustion n dehydration i got there eventually at 11.05am...meanwhile, my colleage was delayed for an hr. so the car wins whoohoo
cruised back home after meeting, checked milage n surprisingly even after kaning the crap outa her to sheffield and cruise back, she did 35mpg. lovely
