Re: How do you "test" a weld?

At least you were wearing goggles Terry, I know a few people who think their eyes are immune to stray sparks!

In my case, I was braising around a Passat rear number plate area (not my Passat!) and discovered that there was filler slightly further down. I reached for the grinder, lifted the (welding) goggles to see while I cleared the filler off and, 23 years later, my left eye still doesn't focus properly!

I bought a full-face shield earlier this year, it means I can wear a disposable mask as well as having eye protection and stops a lot of black muck on the hanky when I blow my nose after using the grinder. The only snag is that I don't notice I haven't put it down properly at times, but I expect it will be a bit more opaque in a few weeks!

Oh Terry, do take care! I know it's easy to say that from the comfort of an armchair but seriously, you'll be lucky to get away without some slight, temporary irritation after doing that. However it doesn't last long and most folk who've been without the full use of their eyes for a few hours tend not to do it again.

I've posted this at a suitable size for you to read if you have experienced some damage but here's hoping you'll have got away with it this time.

I have been blinded in my right eye twice over the years (got mugged once, some thoughtful individual kicked me in the face about 7/8 years ago) and had a grinding disc shatter last year into my eye. The first one took 2 years to heal, the second only about 5 months but it is not something I care to repeat. I was getting irritated with the amount of new holes I was finding, not paying as much attention as I should and made a mistake. I can see properly in both eyes so fingers crossed no damage done.
I will definitely stop when I start getting tired and irritable in future rather than thinking "I'll just do this bit".

Machine mart want £50+vat for 4.5kg of gasless wire. Someone on ebay is selling 5kg for £12+ postage. http://www.ebay.co.uk/itm/Oerlikon-Flux ... 0899810853
Is this normal welding wire as it looks copper coated and the stuff I have at the moment is steel coloured.

I would suspect it's like gas welding rods and copper-coated to prevent rust forming on it. A friend got his MIG out last year, he hadn't used it for a while and the wire was rusty due to a damp shed and our salty sea air. That was half a large roll wasted!

IIRC Oerlikon is a reasonably good firm, but it's a long time since I sold welding stuff.

Just one thing to be careful about - I don't think Clarke MIGs use 1mm wire and suspect you'd have to drill tip out to get it to feed through properly (I suspect the feed rollers could more or less handle it).

Good point, it only goes up to 0.9. I have found a 5kg roll for £38 so I will get that. It's still a better deal than Machine Mart.
