I learned how to braze in high school and I still do so on occasion. Not to often anymore. The torch gets more use with cutting and heating than welding.

Those welds were convex, just a bad angle. The filet weld, the angle makes it look concave. And, I intentionally welded them hot. I wanted a deep weld. That part will see a lot of stress but I didnít want to soak the part and distort it.

I have no desire to weld out of position more than I have to. Iíve stick welded in some weird spots, but rarely. Car stuff usually. And i canít do heights. lol. But I do like boats!

With those screened cups you can stick out quite far. Jody from welding tips and tricks really sells the technique. My gas is at 25 cfm.

I should clarify that picture was taken right after I tested how far I could stick out... the stick out has since been reduced to a more reasonable amount.

i have yet to try the clear cups.

i watched Jody at weldingtipsandtricks on youtube, run clear cups, and they look great!
i'll need to mess around and get some!!!
thanks for bringing it up again 8)

OK it's your money. If you want to pass gas at 25cfm, by all means, do so. I don't know what the refill rates are up in your part of the world are. All I'm trying to say is you can get the same if not better results using half that amount bench welding.
  As far as a clear cup goes, I don't look at the cup, I look where the heat is going. The cup is only there as a spacer. The secret is the angel of the torch to the work.
  The greater the angle the more the impurities will blow off to each side.

Easy there Debbie Downer...
Using this cup has given me better welds than I've been doing previously. I've yet to refill my BlueShield25 or my argon tanks. $60 to fill. And my argon still has around 1000 psi left. Let the little guy have his welds.
I've yet to play with the settings, stick out, and gas settings. Just been welding what's needed to be welded on this belt grinder project and pressed on. Eventually I'll see if I can reduce the gas.

I wanted the bigger clear cup because it does help me see. I can be a bit further away so I can see the puddle better. Jody seems to really like them, I wanted to give it a try, I wasnít disappointed. I'm not a pro, so I'll take my handicaps of they help me along.

Good question on argon cost.   Personally I go thru an 80 CF every 3-4 yrs which = maybe 2 times a year gluing something together. 
Used to be about $40 to swap out.   Last time I did it was more like  $75.
There was a big confloooglio awhile back about argon supply shortage but who knows.   
I want what yooz gots

I think you mean CFH on the flow rate.   Unless its a rocket propelled torch
I run 10-15 range usually

I read post here and there, remarking about the shielding gas prices, owning or renting the cylinders.

Own 2, 80 & 120 .......... just refilled both, under a 100 for them...that BTW is totally reasonable, Airgas bought the LWS, here.

Anyway, I picked up on a unusual bit of info regarding renting these cylinders. It boils down to the following. And have no idea of the time line it follows.

I think it works this way, one rents and comes back every month for a refill. He pays the same price for gas as I.

But rent and then come back a year later for a refill .... big difference in gas price.

 As with any rented item, there will be a regular and ongoing fee.

Soooo even if a cylinder is rented, one may not get a monthly bill, however there is a fee being calculated when the refill happens.

Turns out, as with all things rented, for longer that a few hours it is a bad idea.

ain't no free lunch baby :-\

Very interesting, I need to try that out, I focus on the heat also. Had a total different idea regarding the angle and its effect.

Thanks

seems reasonable, the more I spend for LP, the less the tank rentals are. I have 2 100 gal tanks, and if I spend a certain amount they are practically free. If I spend less, I pay a lot more for the tanks.

Are you suggesting that the refill rate is more if you're renting and refilling less frequently? Maybe I didn't understand what you wrote... I am pretty hungry at the moment.

The reason I chose to lease was two fold; I get a larger tank, and it was less upfront cost.
If I purchased I would have been nearly $300 out the door for a tank that's about as big as my leg. Comes with a fancy pants regulator built on. Then I just pay refill.
Leasing I was $65 for the tank every year, and I think refill (depending on the gas) was somewhere around $50 or $60 for the mix and straight argon. Could be cheaper, I can't remember. So I was about $120 out the door. At the time I was concerned with whopping my credit card with a big purchase and the misses getting her panties all in a bunch come credit bill time.
But, now I definitely hear when the lease renewal comes up on my credit card bill each year.. So i suppose what does it matter. I haven't compared the refill costs for each size of tank. If it IS more cost effective to refill a larger tank WITH the lease against owning a small tank and refilling more often. Frankly, it wasn't a big expense concern for me. I spend more each year to listen to music than I do leasing my tanks...
