i have a very vague idea of how to weld, but could anyone dish out some advice/tips before i start wasting my welding rods on scrap metal, i have no
idea what current setting to have it on either 
any help is greatly appreciated 
The welder will most likely have the general rod size next to the current setting on the scale. Whilst its rough, it will give you a good starting
point.
I'll send you a u2u with a good manual too....
You could do what I did.
Local night school welding course.
Cost £60 for ten 2hr sessions.
Covered gas, stick and mig. By week four half had dropped out, leaving the rest of us make and do pretty much what we liked.
Then I got a cheap mig set, 'cos it is easier then the other methods.
Good luck!
thanks for the replies, my brother has done a bit of welding before and said if i can ARC weld then ill be able to do other types more easily, i just
bought it because i didnt want the bother of buying gas or anything, just want to plug and play n see how i get on, allways prefered the hands on
approach, im thinking about a welding and fabrication course as soon as ive passed my driving test.
would this ARC welder be any good for making a chassis for a car in the future once im good at welding, or will it merely be a good starting point for
a metal spice rack?

It would be ok for welding up a chassis, but skill levels would need to be high
ooo how to make hard work for yourself
so much easier for getting into those hard to get to places
Not easy to use though if never done any welding before.....stick...ooo yer git....stick...ooo yer git.....glow....fuse popped!

im gonna be starting off with thin 1.6mm rods as apparantly these are the thinnest i can use with my setup, and i just happened to have a grandfather
who spent the whole of his life welding theres also 30ft of scaffold pole ready to be cut up and welded back together, shall let you all know how
my welding/hole making gets on 
Tell me about it! If you don't know what you're doing, this method of welding is a pain in the arc!

I did a one-day welding course at the local agricultural collage a few years back. I asked the instructor if it was possible to stick-weld really
thin stuff.
He picked up a couple of pieces of sheet thinner than 1mm thick, adjusted the welder settings and got some really thin rods. He then laid down a
prefect weld about 4" long. I asked him how long it took him to learn how to do that - "about 30 years" came the reply!
The same instructor did a fillet weld into the angle between some 3mm strips. He put down the weld, stood up and said "if you've done it
right, the slag will just curl off" - CLICK - "just like that!". The slag came away with just a touch of the hammer, leaving an
immaculate weld. Smart *rse!
So yes, you can stick weld a chassis - if you're REALLY good...
rgds,

well then ill get the ball rolling with arc first then and may treat myself to a gasless mig for christmas 
just wish i learnt how to weld a
long time ago, still theres plenty of time 
Get some bits of scrap square tube, and try welding them together. Try to beat them apart with a big hammer.
If you don't blow holes everywhere, and the tube gets flattened before he welds give way (or the steel itself tears) then maybe you're good
enough to tackle the chassis!
David
i just bought my arc welder and did some test runs. i used 1.6mm tubes, similar to those i will use for my chassis and i used 2mm welding rods and it
went pretty fine! it took some effort to blow a hole in the tube! and the welds are pretty strong!.
i then decided to make a frame, pretty cool for a painting! i'm loving this!
i have many doubts though... is that black soot which is left after welding poisonous in any way?
what tools can i get to cut metal? i have tried the silliest method, which is using a metal saw, and it is a pain in the neck. what do you people use
to cut the tubes, panels etc?

Make sure that you do destruction and penetration tests before you do anything serious...
The destruction test is to abuse the joint with a large hammer and see what breaks - it must not be the weld that goes first.
The penetration test is where you make your weld, hacksaw across it and see how well the joint is made through the weld. You might have to file it
flat to get a good idea. There should a neat and tidy bit of a weld fillet on the back of the joint.
I would avoid eating the slag that remains, together with any dust and muck left lying around the weld! Your biggest concern should be the smoke and
fumes that fill the air around your head - they are not nice. Also watch out for flying pieces when you chip off the slag, as it's as hard as
glass and just as brittle, and may well be very hot (wear eye protection).
It might be a good idea to post a couple of pictures here, showing the state of your welds - there are a few professional/skilled welders on this
forum who can offer their verdicts.
cheers,
David
My entire chassis was hand cut with a hacksaw! 
for the 3mm panels i bought a large (240mm?) grinder from b&q for about £25 which did a reasonable job
i will post some pics of my welds, as soon as i get more time with the solder. have to get more metal tho.
gav. U DID YOUR ENTIRE CHASSIS WITH A HACKSAW?!!!! i couldnt even cut a single tube today with one of those! i was thinking of buying a good blade
for my jig-saw and use that. i guess that will be faster than by hand
A good hacksaw with a good blade will cut tube pretty well and quickly you do need to get good brand name blades such as Eclipse and a good solid
frame that you can tighten up well. Go to a good tool merchant and he will advise best number of teeth per inch for different materials and
thicknesses. Forget about the jigsaw on tube you will end up with lots of broken blades and sore wrists. Get an angle grinder, good for tidying up
metal messes and can be used to chop through bar and tube though not very accurately or tidy. Get a chop saw if you can afford one to cut steel tube
cleanly and accurately!
On the welding just keep practising with the arc until you are producing consistent good welds. Again buy good rods and keep them warm and dry. You
will take a good few weeks of consistent practice to get reasonably good.
I would avoid gasless mig its not much better than arc, go for a decent Mig not less than 130Amp, you can hire gas bottles by the day from Air
Products with a regulator built in probably the most cost efficient way to get Mig gas if you plan welding sessions to do a lot at once.
Practise and more practise experimenting with rod sizes and amps indicated on the machine until you get a feel for it, remember that actual amps and
indicated amps are not the same on cheap welders, if you can get a good welder to teach you so much the better.
Best of luck, it is good fun when you get the hang of it!

I had serious noise constraints when I built my chassis, so it was hacksaw and file only. Get yourself some screwfix aerosol cutting oil, makes a difference only your biceps will appreciate. If you can get them, get variable pitch hacksaw blades, they last for ages and cut SO WELL!
thanks i think i'll do that. now i know what i have done wrong! doh!
i bought one of these multi purpose saws with huuuge teeth!
i have welded today with 1.6mm rods and they are crap. i'll try 3.0mm tomorrow and have fun blowing holes i think i half nailed it. at first
the rods got stuck and the tip stared to glow, etc. but after reading a book and some advice from my gardener i got the hang of it.
ill send pics pretty soon.
cheers
Try warming the rods first by laying down 1/2" first on a bit of scrap, makes the striking a bit easier. If arcing up a chassis, I would choose Satinex 6013 2mm rods, so smooooth
I agree with the Satinex rods - I've got a box of them and they make life so much easier.
One tip - keep your rods in the airing cupboard until you need them. They must be bone dry otherwise you'll get all sorts of problems. The
college I went to used to keep their rods in a cupboard with a small light bulb in the bottom, for the same reason.
Also, I hold a bit of scrap sheet under the earth clamp, and flash the end of the rod on it before starting the proper weld - this helps to prevent a
cold rod sticking on the work.
rgds,
David

my dad has had a word with the dude that delivers metalfor his rolls royce branch and is willing to let me have plenty of scrap metal for practice
welding, all he needs to know is what thickness steel i want and he'll sort me out, im using an ARC welder and e6013 welding rods 1.6mm, can
anyone suggest what sort of thickness to acquire for just practicing with that wont burn holes easily!
once ive mastered this ill get a MIG and start practising on the same box metal stuff for making chassis out of
[Edited on 19/11/05 by daz]
Most of your chassis will be made from 1.5mm or 1.6mm material, and mostly using corner welds.
Oh yes - get some 3mm plate as well, and try welding 3mm to 1.6mm. That'll test your skills, getting a good weld pool on the 3mm without going
through the 1.6mm.
Have fun!
David

cheers, ill ask for those then think ill test out my auto darkening mask aswell when i can be bothered to put a plug on the extension lead
ill leave out the beer hat till the summer i think
beer hat/welding mask hybrid
