No, been fixed long ago. That article is more scare mongering than factual.

Grahame, they're rock solid machines.

My 17" Titanium G4 PowerBook, hasn't had a cold in 3 years. It'd loaded to the hilt, the new ones - are blistering in their capabilities. They're faster and gruntier than my G5 Quad (2 double core processors) - until I get my Mac pro 8 Core.

A. uninstall Internet Explorer, since it is responsible for numerous security issues.

B. avoid windows which has a near monopoly on malware infestations. Linux keeps a lot of tinkerers happy.

A couple of weeks ago, I wasted the best part of a whole day getting rid of trojans and spyware and repairing the damage left on my daughter's school issue Windows XP laptop, which was shiny new 2 months previously. I can think of better ways to spend a lazy Sunday.

Masochists can run Windows on Apple hardware if they wish.

I'm not sure that you can uninstall IE so maybe it is safer just to not use it. Also, Outlook (or Outlook Express) can be risky.

I would suggest Firefox for a browser and Thunderbird for e-mail. I use Opera and Eudora but these are probably a bit geeky for folks that are used to standard Windows. Also, VLC is a good video player for people who don't like Media Player's auto downloading of codecs (anybody want a nice virus?).

Outlook has been great for spam - as its address book could be hijacked.

You can uninstall IE via "Add/Remove Windows components" control panel. (Until you need to run a mean and nasty web applications that won't run on anything else.) Firefox comes highly recommended and has some nifty add-ins. Also agree with VLC, though has some compatibility issues trying to play DVDs.

I've been using Eudora mail for about 13 years. I find it functional - moreso than Thunderbird we use at work.

On a slightly different issue, PC Mags reliability survey is worth a read (haven't read this one yet, so not predicting the outcome!).

Found some welding instructional here:

Seems a bit machine-dependent. And the person doing the demonstrating appears to be making lots of mistakes. (Grahame would be having a fit laughing.)

Here's a TIG welding video for $60:

Hi blouis79
It just another try by a wannabee.

He concentrated too much on the machine settings-which any beginner should understand are pertinent to the specific situation,material type,filler and individual machine.

A glaring omission was the lack of mention of the the surface oxide or how to treat it. The particular machine illustrated had an arc balance on it among other bells and whistles.It cleans oxides away ,set correctly, but no mention from our expert. Essential in cases where oxide build up causes difficulties.If you fail to effectively deal with it,you can get into more strife than Flash Gordon.

Not a word about the correct stainless aluminium only wire brush or wire brush cleaning the surface before welding either- basic stuff if your welding ali.
One needs to have had experience on a few different type machines and a range of different jobs and materials to know what traps the beginner can run into.

Another contributor kindly made me aware by PM of a glaring deficiency in a mig video offered by a national auto spares retailer. It had the presenter mixing up the voltage control with the wire feed function, grinding with an unguarded angle grinder and not wearing safety glasses under the welding helmet.

I am not trying to sound like I have a big head or anything, but the competing welding instructional videos being of that ilk ,I am confident of the quality and user response to my offerings when I market them.

They are probably a few years away yet.

To get a picture of something exceptionally bright, either still or cinematic, you really need to have a camera with a manual aperture setting capability.

Basically you need to set the correct aperture on the camera for the amount of light and run it before you start welding. The picture you get at this stage will be almost black. Once the arc starts you should be able to record exactly what you require, which is the welding.

You will have to enclose the camera, possibly in a wooden box with a piece of thickish glass for it to look through. Timber doesn't transmit heat so it will insulate your camera, glass will not melt like plastics when pieces of hot metal touch it.

The best idea is to put thin sheet metal on the outside of the box so the timber doesn't burn.

You may need neutral density filters to reduce the amount of light. Possibly a welding filter could do the job. If you use a welding filter I don't think an automatic one would be the easiest to work with. You need a filter which is constant so your image density on either film or a CCD stays the same.

I have done still photographs of welders over the years and there are two main possibilities. One, you get a recording where the overall scene shows all things, the welding arc is blown out to sheer white. The other possibility is where most of the scene is extremely dark, but the work piece is recorded successfully.

By the way I do arc and oxy welding.

Miller has some very useful resources, including videos (animations sadly) and downloadable handbooks....

Hi Graham,


For the last couple of months i have gone from not knowing a thing about Welding to knowing..... a little bit more . I would represent one section of the demographic that i think you would be interested in. I am starting from scratch trying to get into welding.

At tafe they have a collection of the Mig,Tig, Arc, Oxy, and handtools video's where the teacher puts them on and leaves the room. They are just as you described them, dated very dated. (oh yes and boring)
Safety is always important as i learnt using the Grinders at school , but i just didnt know until someone told me, "hey, you do it this way". Helmets and safty clothing do's and donts. Telling people about the reset button on some of the autodarkening helmets so they dont get flashed on the first weld ( me).

I think telling people why they need to weld a metal, and what the actual welding process does, also showing (indentifying)the different type of steels alloys ext. and how they react when welded.(i say this because i went from learning to weld steel which I was ok at, then to welding Stainless and now im back to frustrated).

Alot of videos theres a guy in a workshop in some factory welding a piece of metal and doing it perfect, would be nice to reproduce some bad welds or common mistakes and then show what needs to be improved or changed to get perfect continues welds.

Mind you I am only talking in relation to TIG as thats as far as my experience goes for now.

I hope this helps a tiny bit, I have been looking for some instructional videos to buy, but never found anything good. The miller website helped alittle, utube also, but never something solid that fills gaps which sometimes your teacher at TAFE doesnt help you with, mind you the teachers at my TAFE (chisholm Tafe VIC) are very good, they say that theres not enough teachers , theres just no insentive, so what you get are 1 or 2 teachers walking around with a line of students constantly calling them over to there booths. They run around like chooks with there heads cut off.

So to end my 2 cents worth, im really excited about someone creating something to teach the welding art and I would be one of the first people to purchase it as I need all the help i can get.

Good luck and please keep me informed, and if you need any help with computers or anything computer related please ask as my "real job" is IT and has been for the last 8 years.

Regards,

Paulo

Hi Paulo
Many thanks for your kind offer.I will take you up on it at some stage as computers are a mystery once I venture beyond some set programs.

As an ex Tafe instructor I have probably seen the majority of the video offerings. Yes I have some strong views on them and how they should be made.
The problem is that the current ones are just the production companies ideas of what welders should be ,told,instructed ,directed ,educated etc.

The way to engage a student is not insult his intelligence and thats what some of these videos do.I used to laugh when some talking head in a white shirt ,tie and dust coat started spruiking about welding process.Sitting there in my work clothes I could feel absolutely no empathy with the presenter at all.

I used to sit there and wait to pick holes in his delivery. A bit negative ,I know but if your there to teach welding you have to look like one as far as I am concerned.


The basics of welding, I have learned on the job but the theory refinements have come from books,videos, dvd's,and websites. No one can learn welding with just practical or theory alone .there must be a balance of both.

What I would wish to do is offer a process at a time and incorporate as much as possible in each dvd broken down into sub topics that the viewer could digest easily.

Segments that would run for no more that 10 to 12 minutes at a time.


As far as understanding the metals I would approach that from a physics basis. Stainless steel is another metal altogether after one has welded mild steel as the heat conduction is completely different.Once you begin to understand the differences in the co efficient of heat conduction between the different metals ,the pennies begin to drop a little faster. Learning the little tricks in identification of similar metals helps too.

Rest assured you blokes on the forum will be the first to see the finished dvds.

Cheers
Grahame

Found some interesting welding source material:
