Re: Took a stab at the coke can thing ....
There are two tricks to razor blades.
1) Tack at both ends this keeps the gap consistent through out the weld, This is very similar to a number of cwb / aws tests.
2) if you are just doing it for a party trick, with no filler, have them butted right together, tack both ends, then use a touch more heat and move fast but consistent one end to the other. It will take a couple of tries to figure out speed vs amperage, but after you do, you can pretty much do it every time.
After 5 years of certified welding, keep in mind I haven't welded as a job for 4 years now, I can still do most of the party tricks I learned along the way: Welding beer cans together either halved or end to end, razor blade, spray transfer vertical up, 7024 vertical up. ect...
At one point I was doing 7024 vertical up so often, that when it came time to renew my cwb structural cert (can't remember the numbers anymore) I did it both with 7018 and 7024 all position. I kept those tested welding strips for years hanging on my wall. (Yeah, I know I am a super geek)
To make a longish post short, mostly they all just take practice, and they all have there tricks to make it easier.

I had to have mine legally destroyed by my inspector
I'm going to take a stab at the razor blade thing tomorrow
It was -38*C a few nights ago where I live...

Re: Took a stab at the coke can thing ....
Anyone else going to try the center of the can so I can see how I did?

Re: Took a stab at the coke can thing ....
cool.. For some reason I had problems with my high frequency start going haywire at that low of amperage. I had to start on the table, wait for it to balance it out, then jump onto the piece. I really should have taken the time to take out the 1/8 tungsten and replace it with something smaller lol but i didn't give a ****

Re: Took a stab at the coke can thing ....
When I was welding the can in the center, I had a decent line going then I would blow a hole in it. Man i was yelling and screaming, made me pissed at my girlfriend cause she made me quit smoking, it would have been a perfect time for a cig....
Anyone else going to try the center of the can so I can see how I did?

Re: Took a stab at the coke can thing ....
looks great for 18 days.. I think you're lying and you obviously have a better camera than me.. along with fancy paper to lay parts on.. What filler did you use? I used .035 wire out of a mig, and I actually heated the wire right next to the blades so it dropped onto them once it formed a puddle. That seemed to help keep the part from melting away

I envy you ppl with your HF start tig's. I'm having tough enough time with my cheap POS H-F toaster with scratch start. Not bad for 1/10 the price tho... I feel like a crippled genious who can't afford a wheel chair, lol.

Pics from the days efforts. Done on my dynasty 300dx, its an older one, only goes down to 5 amps.
Coke cans, no pulsing, positioner etc.:
That was the best of 5 sets, I tried halving the can on one try, it was thin, about .004", didn't have any luck, I needed to go below 5 amps and my machine can't. Will have to see if the 200dx goes lower... I need to practice my Al welding, seem to only weld it every couple of months.
Razor blades, these were easy:
Parts from some production pieces I had to run:

Re: Took a stab at the coke can thing ....
wow good job! i tryed doing the razor blades i found liying around lol i got about half way and then i started blowing trhough it so i just jammed on the pedal and completly destroyed the razor blades out of frustration!!! ahaha
but i can seem to get the puddle starting on the al cans, it jsut starts the burn and then eventually it blows a hole in them
i just got my Miller Diversion and im still learning the machine... It welds great for small projects at home it goes down to 10 amps.
what are you guys setting your machines at for the Coke Cans? what size and type of tungsten are you guys using?
Keep em' coming guys

Re: Took a stab at the coke can thing ....
are you guys serious about welding the cans with the beer/pop still in them? ive been thinking about trying it and kinda think the liquid might help with not blowing a hole through it but then again when the liquid gets hot its gonna build more pressure than its already under and then it would want to blow OUT of the weld spot. id really hate to clean pop out of my torch and wasting beer is just a no no.

Re: Took a stab at the coke can thing ....
When I tried re-joining the two halves of a Coke can I cut in half with my Oxy/Acetylene torch (with a tip that is WAY too big for .004" material) the plastic surface caught on fire and burnt up the can. It was comical. I may get a Meco Midget torch one of these days and try it again with the outer surface of the can wire brushed off. .004" is a tough one though. . .
Dave, those welds on that DP or whatever it is are INSANE! ! ! There are definitely some hot welders on this board!

Re: Took a stab at the coke can thing ....
Well, got bored at work, and found a few old Olfa "art knife" (scalpel) blades, and went to town.... Started out with just welding 2 together, and it just snowballed from there!! I ended up with what I'm calling "OLFA SURFER" made out of 6 blades.
Read 'em and weep, bitches!!
Put a penny in a couple of shots so you can get a grasp of the scale.
ENJOY!!
