Is it normal practice to grind welds to tidy them up or should the weld be left as it is then painted  Obviously my welds look a bit crap at the minute  but with a flick of the angle grinder they look better 

I would say yes, but only if the weld is good enough to be cleaned up using a grinder, you wouldn't want to be grinding away all the weld...........

Dressing with an abrasive disc of some description would be prudent, but if the panels being joined were prepped and welded with some forthought, then the surface finishing should be minimal

Ah yes , dressing is what i did but a bit too much 
As the saying goes 'things can only get better' .. more practice ect .
Need to build up the welds more and set the amps lower , stick is sticking on strikes
a bit too much then burning through although its only 3mm tube .

What do these poxy hobbie bottles cost these days?

What size are they?

If starting from scratch, you're probably looking at £150 by time you have paid deposit on bottle and bought regulator and adapter. Rent free though

Can't remember what refills are, £35 for argon?

150 for the gas? Ouch. That is major money, I presume that is argon?

[05omegav6]

Nope, +150 for the bottle and a fill of gas

[deviator]

No way, I'm trying to remember what they charged me last time I bought some, I think Co2 was 20+vat for a refill. I seem to remember argon was 50-60 deposit and 30-40 per refill. I suppose by the time you've whacker a regulator on it, it'll be getting up that way.

[05omegav6]

I think that was Tbs point

Definitely grind the welds down if they look shite like mine.  Though don't go too far as you'll remove the weld.  You could weld a bit.  Grind a bit.  Weld a bit.  Grind a bit.  I do this cos my welds are shite lol

Sorry about being late to the party........

Co2 pub bottle refill (welding gas NOT pub Co2) was 20 quid
Argon/Co2 mix was 50 quid deposit for the bottle and 45 quid for the fill, so 95 quid for a bottle slightly bigger than pub Co2 bottle.

They asked if it was garage or mobile, I said mobile (IE can move bottle!) as they had workshop bottles about 2-3 times the size of the little bottles at 70 for the fill (I didn't ask about deposit on those, sorry).

These aren't guesses, these are the prices I paid the other week at the gas place at the end of my road. If you are local to me, I can recommend them!

*** Please note the argon bottles use a different sized thread to the Co2 bottles. So budget for adaptor or a new reg with both types of fittings. My place sells regs, but eBay is better on prices ****

The gas shielded welds are so much more cleaner and stronger , will be looking into buying a gas mig in the future . Plus mig wire looks cheap enough and more economical , plus more handy for welding thinner gauge

I'm still very much learning. As such, I had the FiL's Co2 bottles off him, he has gone over to Argon. I want to learn in the worst case scenario and then improve from there.

Photos please. Come on, I was brave enough to show my crap welds 

[EMD]

I only used about 8 arc rods to finish the welding cart , but it was intricate work you see  Really need a mig welder for thinner stuff like body panel thin plate steel which i have a small pile of 

How much you want for that mig you dont use anymore mr webb

Go on then, you can laugh at my efforts......

















This was on my own unsupervised. Hence why when I was working with the old thin metal, it kept going wrong and I had to turn the welder down. Please note none of these welds are staying, they are a temp install until the garage is extended.

Er.. 99p?
