todays update.........

a few days off for Easter, so I thought I'd carry on with welding practice.

waste of time !!!!

I couldn't do anything. No penetration, had blobs of weld everywhere, most of which would come off by picking them, tried all different settings .......... failed miserably

A few hours on the interweb, and it would appear my gas has run out.

but.......Found a supplier of Adams Gas nearby, so tomorrow I'm going round to get me a 9L bottle.

Chrisw8 · Apr 24, 2014

got gas !!!!

got all the bits needed to make it fit !!!!

pulled the mig trigger ..........

...................

gas ****ing out over my hand through the trigger button

opened up the gun and there's sealant everywhere.

* must have a word with brother about buying welders at car boot sales *

so,

spoke nicely to missis, and with birthday coming up in September ........

we're off to Machine Mart on Sunday to get a new Clarke 150 @ 15% off.

blue or red ???? so many decisions !!

so today. I've been rubbing down the footwell and gave it a coat of fertan, ready for painting.

first dibs on buying your broken mig

if you want to try and fix it, we could probably help guide you.

also, http://www.weldequip.com/mig-welders.htm (not the cheapest, but has decent stuff)

i think that smartmig is meant to be nice for around the same price

hi Trax

thanks for the help, but I think bro' is going to keep the knackered welder under the bench ....... for gasless use.

......plus, I like the idea of a nice shiny new one !!!!

I've had a look at weldequip, and for what I want to do, they are a bit too out of my price range.

fair enough, i'd also have a quick look on ebay for a used good brand.

a good brand will have new parts available to fix it up if needed.

upto you though

so today I tried to weld a bit of the old wing onto the new metal

tacked the old bit

your gonna learn to pulse weld.

welding with the current higher, the trigger is pulsed quickly, second on/second off/second on etc.
sometimes you'll get 3 or 4 seconds on, couple of seconds off, all depends on the gap your filling and the thickness (or lack of it) of the steel.

the holes on your practice work would be easily fillable, tho with time you'll be able to see when the holes going to blow, and either adjust your pulses to shorter weld, longer cool off, or stop the weld and restart againg half an inch away, going back after to weld the gap.

you've some nice looking welds there, inc the tacks. what welder have you got?

Chrisw8 · Apr 29, 2014

will have a go at pulsing tomorrow.

Thor........I'm avvin trouble doin the front step, never mind the back step !!!!

*off to google back step*

Not that easy to blow holes in 1.6mm at the lowest amp setting I would have thought, unless you are holding the gun over the same spot for too long. I have never needed to use pulse welding with a MIG, just make sure the gun is never stationery, except for tack welds of course. Even for plug welds, you keep it moving in a circular motion, I seem to remember.

trax · Apr 30, 2014

also, arn't disco panels more around 1.2mm? if so you might find yourself blowing holes discoside until you get the hang of it

Chrisw8 · Apr 30, 2014

Yes, that's the problem I've got.
I've practiced loads welding the 1.6 steel, and am quite happy with the results.
It's the welding 1.6 to steel from the old wing ( 1.2) that I need to practice now.

try to stay longer on the thicker steel or buy some 1.2

Chrisw8 · Apr 30, 2014

Not buying any more steel

I'll have loads of practice with chopping bits off old wing and get to grips with it.
