You may well be getting a different gas coverage when you are doing the other joint types.
Can you organise some “dams” from aluminum foil to help contsin the argon?
What are you “aiming” the arc at?

Thanks Sandow
I look forward to seeing that.
I actually have enough large heatsink extrusion to make a tank, also have 120mm fans as well but it I expect, the pump that is the bulk of the noise of a cooler.

Thanks Kym
I will check it out once it arrives. Not there yet.
Thanks

Hi to all In my contemplating making a collet it seems that people either go for a Procon pump or a Shurflo pump. I don't want to end up making a cooler that is noisier than my Miller DX200 welder. Potentially you can get away from fan noise by having no fans but a pump is unavoidable. Is there anyo...

Nice job of stacking beads, well done Kym

Hi Xryan yes a Dynasty DX200. Very happy with it despite having initial issues with it as discussed in one of my first posts with getting an arc to start. Here is a bit of recent 'work'. I decided my old van needed some cup holders. https://dl.dropboxusercontent.com/u/24636206/wtat/2016-04-10%2011.4...

Hi Kevin yes I know what the duty cycle for my DX200 is. At 200A the duty cycle is around 20% and 60% at around 150A. No problem there. What I was curious about was how other people keep track of that 2 minutes in 10 when maxing the machine. Particularly when you are doing lots of little sections of...

Hi to all the subject probably sounds grander than it really is. The question is how do people stay within the duty cycle of their welder? I guess it applies to any welding method but TIG is my usual method currently. A lot of the time it is not an issue but other times you have everything tacked in...

Hi Jody I am sure that others will agree but I would say that this was a great video even without any need to put a welding helmet on. Great advice that applies to many situations. You never quite know what will result from taking advantage of opportunities, asking questions and paying attention. Th...

Hi Tokoroa_Welder
what sort of system do you want to be doing your practice with? DC only? Output amps?

Hi Richard working with IT environments is my daily work. I was not suggesting the loss of material due to carelessness but more the failure to transfer the content due to differing back-end structures. I have seen this loss occur in my own workplace due to political/time/cost priorities taking prec...

Hi LtBadd
other times I have seen system changes like that, historic material gets lost and I wouldn't want to see that occur.

Hi to all finally getting to post this bit of work that was done in time for Christmas. The pergola over our deck needed a refurbishment and I managed to get some aluminium extrusions (rectangular, 100x25mm 2.5 & 3.0 wall thickness). https://dl.dropboxusercontent.com/u/24636206/wtat/pergola%20%2...

Hi to all I managing to burn out the motor on my horizontal bandsaw after being left on it's own to finish a cut on an aluminium extrusion and the blade getting stuck as the cut was about to finish. SO time for a new motor. Also decided that since I was at it I would build a new drive belt guard for...

Hi Kiran I found this product literature for the 280 version https://www.millerwelds.com/~/media/miller%20electric/imported%20mam%20assets/spec%20sheets/e/d/1/dc29-55.pdf and I see in the specs that it is DC only. It is apparently not impossible to weld aluminium with DC but you will be setting your...

Hi Kym
how about plug welding the sheet to the tube?
Or how about laying a bead on the sheet, flatten the top of the bead slightly and then place the tube onto it? That should give you a bit more space to weld into.

Ralph

Hi to all I realise that my question may be simplistic but id the pinhole that is found is more a pin-cavity as compared to a pin-tunnel that actually leads somewhere, is it a problem? Is it possible to perform a leak test as you might do with a header tank etc? With many castings, there may not be ...

You can also have a go at straightening it by running a bead on the back. Don't add any filler just apply heat. Similar process to what Jody used to demonstrate in a video on straightening a shaft.
Used to be done by heating with an oxy acetylene torch

Hi Kym I have just logged into my BOC Online Store account and figured out that per volume of gas that Argon and Argoshield are 80% and 76% respectively cheaper per cubic metre in a F size cylinder than a D size cylinder. I couldn't find the rental amounts to take into account as well. It may be wor...
