Movement Speed

Hi Lads,


Finally had a go with my Clarke 100en welder. Using Gasless wire and steel of about 0.8.

As suspected I made a right mess of it. But its first time even turning a welder on. Yes a bit weary when I first started. But then the nurves disappeared.

I finally after a few attempts, managed to see what I was actually doing behind that dark mask.

I know with thin metal you are soppose to do little bits otherwise you blow holes even distort the metal which i did on some of my practice bits.

I am practising using thin steel as I will be or wanting to weld car body panels. I am using gasles as I do not have a garage so will be outside.

So my question is this. When you are welding away, say in a straight line at what speed roughly are you moving or should I be moving. Or is this just a judgement thing.

Also on an occassion I found that the wire came through and I had to stop, cut it off. Did not seem to get an arc if that is the correct termonology.

Also wire speed for thin metal I found to be at around 5 - 6. Would you say that was about right or should I just keep experimenting.

There will be many more questions to follow. Later

Cheers

Dave

Hi,

it's diffcult to judge...

as the metal melts it creates pool, and you keep adding wire to it making it bigger. When it gets around 6mm (1/4 inch) or so you move the torch slightly so the wire points into one edge of the pool, the wire melts and the pool stays the size that it was as you 'tease' it along in a straight-ish line, with the back end of the pool solidifying.

That's basically it...if you move too slow the weld is a bit wide and too fast it becomes too straggly.

Poke'n'hope until you get used to it.

It's best to try multiple runs along a plate at different power settings and different torch speeds. Post pictures on here for specific advice. It's harder to try to explain it that it is to actually do it.

Regards
Peter

Practise on some thicker metal till you get the hang of what is happening or you may just get frustrated with blowing holes. It's easier to work your way down to the thinner stuff than start on it even if it is what you will be working most.

Hi Guys,

Many thanks for the helpfull replpies. Yes I will try on thicker metal.

I will just keep experimenting.

Cheers

From memory the average manual welding movement speed (Assuming your welding in flat position and you have appropiate current for the material thickness to be welded is around 30cm per minute)

Blimey! that feels slow to me! that's when you're welding on low amps, Matt?
