[GALLERY=][/GALLERY]This is the latest , I cleaned it up , and match a patch , it didn't work , the welder has setting 1 and 2 and high and low as well as feed speed , feed 1 seems to just make tiny grey burns and setting 2 gives me a sunburn and is hotter than the sun resulting in holes blowing , any ideas , I've seen lots of tutorials however it appears to do nothing or create a furnace , I did grind paint off patch before attempt , spent 2 hours on it then Gave up

What is the model of machine? If you look it up then you’ll find a chart which will tell you the actual (approximate) amps you’re using for 1-low;1-high;2-low;2-high. I would guess that you need 1-high or 2-low, feed speed somewhere in the middle. Just keep trying the combinations on some scrap until you’re happy. Tip distance will have some affect too, but not so much with a flux core setup. Have you got a nice clean earth point? Also, look up stitch welding, might be more suited for your task.
 
I'm no expert but from my limited experience the metal needs to be spotless and ideally, without big gaps between plates. Not always easy to fill them holes with weld.

Yup post #7 told ye they were sh!te now you've wasted time & effort an no further forward in the
last couple of weeks, if you were closer I could have done that repair in 15mins start to finish.
Cheap tools are cheap for reason. They are pishh. Sorry but your wasting your time mate.
 
Funnily enough I was doing a bit of welding on mine today.
Old Clarke 151EN I've had for years. Converted to eurotorch a few years ago & using Argoshield Light.

You aren't going to bridge those gaps.
You need the patch to be a good close fit if you're going to butt weld. That one isn't.
Cut a new one slightly oversize & use an angle grinder with the red grit discs to shave away a bit at a time until it's a good fit. A big welding magnet (Aldi, Lidl etc) helps to keep things in place where you can't use welding clamps.
Then tack it in place & join up the tacks.

Also if the metal aren't of the same thickness you'll tend to blow holes in the thinner one.
 
It also helps if you use a bit of cardboard as a template for a patch. Just keep trimming with scissors until you're happy with the fit then just trace round it on your steel sheet & cut out.

If you use thinner card then once you've trimmed the metal to good steel hold the card over the hole & run your dirty finger over the card round the edge of the hole. You'll leave a mark which will make it easier cutting the card template.

It's easier to how holes in thinner metal with an arc welder, it can be harder to get a deep penetrating wild with a mig, but practise makes perfect!
Whatever your welding needs to be very clean and rust free when you use a mig and it doesn't work so well upside down.
Make sure the earth clamp making good contact with whatever you're welding

Ignoring the fact you seem to be drunk while in control of a keyboard, with the correct settings and skill, MIG works perfectly well upside down!
I suspect any issues YOU have stem from the fact you can't weld...

As you can see after having a poke around I have quite a big hole in the rear of the 88 , I Also have a huge hole In the chassis that I need to weld .
I have a gasless mig welder which I have used for floor panels in the past which was great . Yesterday I attempted to repair these holes with it , it was CRP, I spent more time fixing the flux core feeds than I did welding , I think I ended up with over half a roll on the driveway wasted .I have a few questions , the flux core kept buckling up and snapping which resulted in me wasting loads of it , it splattered all over the place , with no actual weld , the metal was clean , the clamp was good. , Could the roll just have been bad? , does it go off ?

Also for such sturdy welds , not panels etc , should I get an arc welder instead , I was always put off as I was told it could blow holes in panels but I'm not doing panels I'm doing the rear and box section of the chassis ,


I'll probably try new flux core reel first before buying an arc welder , however if im wasting my time I'll sell mig and but an arc welder

Any advice , thanks .

I'd ditch the 'gassless' and get gas!
Many places now won't charge you cylinder rental. You just pay a deposit and then for the actual gas.

AMEN to that!
I'm a welder and much prefer to let my cousin weld on my car. Yes i could do it myself, hell, up until about five years ago i would do it myself. But i have a driveway and a trolley jack and axle stands and he has two four post and a two post ramp.
Ramp beats axle stand EVERY day of the week!
He often offers to just let me use his ramp and my counter off is give him cash and to call me when it's finished.

not drunk, but sometimes always autocorrect is way to invasive!!
sorry, I wasn't clear, but was specifically referring to gasless/flux-cored wire re. upside down. maybe gasless has improved over last few years, can't comment about that
