Here you go - welding tutorials online! http://www.mig-welding.co.uk/

Forum advice as well. I found the self-darkening helmet to be my best investment ever.

But I did get a picture of the front showing the AMPS switches in yellow.And the wire feed in red.

That is one of the best DIY welders you can buy. I've used that make for years and they are a great machine.

Borrowed a sealy welder once and could not use it as the wire feeds before teh gas starts causing perosity in the weld. Seen a few other machines that have the same fault.

I took a course at night school to learn welding. It's amazing how easy it is when you have the right equipment. I have a cheap gasless MIG at home, and it's useless!

I too have had arc eye. Same thing, 3AM and I woke up in agony, I ended up in accident and emergency for a few hours.

[Steve and his 244]

Very well done for having a crack at welding! Looks bloody good for a first time too! I havent read the whole thread so i dunno if its been mentioned, but you should always disconnect the battery earth when MIG welding.

[minesa240x3]

Whoops fancy me forgetting to say that steve.
Yes always disconnect the battery BUT BUT make sure you have the radio code or hope it's the genuine one and any volvo dealer should be able to give it to you on the basis you have the registration number.

And it's not likely but never weld in the rain as it can be quite a "SHOCK" when you get all those amps travelling up your arm.I've done it through neccessity not nice.
And as we are talking safety a fire extinguisher might be handy too,Just in case.A CO2 or powder type.Or the old school way is a really big rag soaking in a bucket at the ready Lol.
And don't forget as you stand back to admire your handy work it stays hot for quite some time.
Another good bit of advice is to finish welding and check for at least an hour after that everything is ok.No smouldering embers etc.

These new fangled gasless migs? How do they work then?Has the wire got a flux running through it?

The street lites shouldn't dim plug into a standard domestic 13amps wall socket but use the shortest mains lead you can and make sure it's got an earth cable as many these days are two core.And if the extension is on a roll then unroll the whole lot as left wound it will start to get warm.The more windings the warmer it gets and the loss of power will be evident.The coiled wire also creates a magnetic affect.

There must be loads more I've forgot so feel free to add or even correct what I have written as I'm no teacher just a bloke who pass's on knowledge to the best of my abilities.(or lack of Lol)

Regards Brian.

Gasless migs use a special wire with the flux running though it. They can be OK for welding bits of scrap together but not really good for car bodies. I found mine very difficult to control and the welds are very difficult to grind flat. Maybe if I was better at welding then it wouldn't be so bad.

As a rule of thumb, the more expensive the welder the easier it is to control so you get the best penetration, so ideal for beginners. (this is only my opinion though!)

Regarding the 13amp plug socket, I found using mine would trip the main house breaker off. Instead I have to use the 30amp cooker socket instead. The wife LOVES the dirty extension lead going round the kitchen worktop and out through the window!

I guess if you have a big french door or the like you do the welding in the lounge. Closer the the cooker power
Best to have your bags packed before you start the job!!

More hacking away done today, i've done a lot of preventative maintenance so I've cut areas which weren't holed but would have caused an issue in years to come.....hope this pays off....it's a lot of work but i'm learning new stuff as I go and she can only be better for it.

Was gonna do this in one patch but fitting it was a pain...I reckon I'll use three patches in the end....rebuilt the end on the inner sill too.....the discolouration in the middle of the patch is where it's welded to the inner sill....

PS.....the welder was acting up today....does damp weather affect them?.....seemed to take an age before she started to weld nicely...

Regards,
Shane

To combat arc eye wear a good pair of safty glasses eather clear or dark they stop the uv light and don't weld wearing contact lenses!!!!!!!! just for info the swiches control the arc volts and the wire speed controls the arc amps
