Cyanide is only an issue on galvanised steel, prep the surface with a grinder and its not an issue.

[aaronjb]

A little cyanide never hurt anyone, right?

That does look like Webby when his cam belt snapped and he had a fag to calm his nerves

Silly boys 

Re, welding am i right in thinking that if i get a load of spatter (balls of weld flying everywhere, covering the work piece etc) that i have the settings too low?

If i hear an internittent cracking then my wire speed is too high and i need to bring it down til i get a continuous buzz or ''sizzle''?

and finally.... with the clarke machine can i go between two wire speeds i.e. have it on 3.5?

[Kevin Wood]

I was taught that if you are getting just a very clean hum with little crackling or sizzle you are probably welding in spray transfer mode which is probably not what you want. You need just a little more speed on the wire feed until it starts to crackle. Then again, I'm no expert.

Thanks Kev,

My ma went to the local metal fab shop and they gave her a bucket full of 2 - 3mm steel for £10 for me to practise on (not scrap...they actually ct out squares for her )

So, going to see if i can improve using the thicker metal.

Even though i consider my first effort a disaster, i got it right two or three times so i know exactly what to look for to say ''yep, thats diong well''.

if i still cant get it right theres a guy in notrhampton on the welding forum who has offered to spend a couple of hours with newbies to teach them.... ill PM him and see if he'd take pity on me with offers of beer and beef jerkie (god that stuffs good)

By the way - I have that same welder and I cannot get enough shielding gas out of the torch unless the regulator is up flat out. Turn OFF(!) the welder, and see if you can hear gas hissing from the nozzle when you pull the trigger with it near your ear.

Thanks Kev,

I'm definitely getting some gas cos when i pull the trigger approx. half way i can hear it hissing out. Thats with it set on 4.

If the gas doesnt come out and/or it's blown away will it cause those rusty looking welds i had in my pic? Any other issues lack of gas creates (just so i know what i will run in to)

people say it causes porous welds but ive no idea what that means visually

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

If there is no wind then you need hardly any gas, 'a witches breath' was what I was always taught.

Get outside and the shield gas will soon disperse at which point you will need it flat out.

OK. I can't hear anything with mine until it's up to 6, so there must be some variation between the regulators. Sounds like you're OK.

[Webby the Bear]

As mentioned sadly being indoors / garage isnt an option unless i spend many hours clearing my dads stuff lol to which he'll be very upset.

ill defo go with the windbreak.

The very same. Probably down to the canister, even, as I think it just has a pin that acts down on the valve in the tip of the cylinder.

Really must get myself a pub cylinder.

I've gone with the double capacity tanks. but if they too run out as quickly as the first did (i suspect) then ill have to invest.

are there any other offers to consider on big tanks? and you rent the tank and just pay for refills. (or rent free as someone elluded to earlier)
