Ok, had a good butchers through the interweb. i'm defo convinced that i either ran outta gas for that last weld cos they go brown and start spitting balls of metal...exactly what happened.

as i dont have a gauge on mine ill attempt it with same bottle out of the wind. if same thing happens i know im empty. if they go well i know that it was the wind

finally, even though ill be practising on some thicker stuff id like to go back to the 0.8mm i have. lowest settings (1 min) and a play about with the wire speed.... as last time i didnt realise i could go between numbers e.g. 3.5

If you're out of gas then there should be no noise of gas escaping when you pull the trigger.. so that's an easy enough test, right?

Very true mate. in my lack of knowlege i simply thought id got the settings wrong as i was changing them all the time. but now i think i understand

if there was no gas left but the canister is still pressurised is it possible it'd just be air i'd hear gushing out? sorry if thats a retarded question

No there's no air in the bottle,only gas so if you can here it hissing you still have gas

Sweet. Thanks Henry.

Looking forward to giving it another good go tomorrow. Got 3 of the double capacity bottles turn up today. So hopefully that wil lbe enough.

Got loads of metal too. The pug door (0., some 2-3mm my mum picked up for a tenner at the local metal fab shop and some 4-5mm scrap my mate's dad picked me up from the scrap bin at his mate's truck depot. So all that metal.... £10. happy bear.

Practice on the heavier bits of metal first and play with the amperage/wire feed a bit until it sounds rights,a nice buzz with good penetration,oooh er missus

[Webby the Bear]

Will do mate thanks.

one final question. (sorry)

does the wire feed setting equate to how many metres it will churn out in a minute....

e.g. setting 2 will chuck out 2 metres per minute?

thought i read that on the net you see

I don't think so. The wire feed rate isn't constant, for a start. As you draw more current, the welder increases the wire feed rate.

[Webby the Bear]

Understood. thanks mate 

Piccies of another round of disastrous welds to come tomorrow 

[Sir Tigger KC]

Ill PM him and see if he'd take pity on me with offers of beer and beef jerkie (god that stuffs good)

Offer him Biltong instead.. makes beef jerky look like the dried up boot leather that it is..

Biltong!! Mmmmmmmmm......

Afternoon fellas.

So, got some 2.5mm and todays aim was to lay some beads. I am very pleased with how the welds look (even got some ''C''s in there  )

I did this in the garage and upped my gas to 5. there was definitely no wind and definitely there was gas coming out the end but still got that brown residue on them.  but all in all very very pleased. I got the settings spot on. I realised I was holding the tip too close. and I realised I was moving too fast! corrected these and the weld pooled up real nice. but all about getting the settings right! 

The breaks are where I had to stop to reposition and cos I stupidly brought a non-auto adjusting helmet  I missed the restart point....



penetration. good???


and I had to stop cos I got to go and pick up some stuff from a mate. but I had to have a go at joining together



Beautiful? No. Getting better? Indubitably

[Marks DTM Calib]

Penetration looks ok

You need to work on creating a more consistent weld, I find the key to this is to watch the weld pool and not the tip.

Oh for info, the distance from the work piece impacts the current.....

[Webby the Bear]

Thanks Mark,

Thing is I'm learning all the time. I found that best for me is to go up and down with the torch and tilt my head to the left to see the pool. But it was all about trial and error. And I'm not scared to try. and error. 

Re the distance... that would make sense because some have no spots and some do. Just got to findthat happy place.

All in all im really pleased though that I'm improving and not stepping backwards.

Are you cleaning the splatter build up in and around the nozzle + using anti splatter 

Are you dragging the tip in one direction or rounded E's although thats more for thin to thick welds without burn through on the thin .
Count 2 seconds on the trigger for a spot weld .

[Webby the Bear]

Yes mate, gave contact tip and nozzle thingy a good clean. I find the build up of spots comes off real easy. I've so far only needed to blow them away.

Rounded e's. . . . No 

I'm currently dragging the pool towards me as that's what's most comfy for me. I've tried a bit of zig zagging also

This is going to be an exercise in practise!
