I don't believe this will work

Looks good to me and at the end, you can see the weld is virtually flush with the surface. Unlike any stick weld I ever did!

That's because the weld is sitting in the space between two radiused corners at the edges of the two bits of box section they are using and the wood on top will also be forming a dam and keeping the molten puddle flat.

Well, yes. So that's a good idea right?

Albeit one with limited application.

Itll be no good for welding curves and pipewrok!

If one was on an expedition with a group of vehicles in the middle of nowhere, had some welding rods, crocodile clips, and needed to repair something structural, and also didn't have a welding helmet or any other ppe, then perhaps this could come in useful!!

What size rod was it that they used?

I've not done any stick welding for years, and I only have only ever used 2.5mm rods. I have an old 140A buzz box, and I stuck with that size rod as I always believed that was all it could run!

I'm guessing that they did a weld of maybe 300mm there? It looks a nice fat chunky bead, and I wonder how many of my 2.5's it would have taken. Several I should think.

What size rod could I use on my old machine? 6013's obviously...

With 140 amperes maximum, you can burn well even 3,2mm rods.
If the duty cycle of the machine permit it.
As an aside, you can run 2mm and 1,6 mm on your machine, if you will.

That's good to know. The last time I tried to burn 3.2's it wouldn't arc up, but I was only a boy then (and didn't know better!), but I think they may have been 7018's. I 'acquired' a whole load of rods, and some worked and some didn't. I was too dumb to read what was written on them, and the Internet hadn't been invented then so I couldn't ask on here!

Also the quality of rods is to be considered, and being dry. The difference between nice rods which are dry and poor ones with damp can be like night and day.
You need 6013 rods for your welder, there are loads of good ones available (I like Murex 'white box' and Pheonix), avoid unknown brands such as anything sold by general tool suppliers (Machine Mart etc), Super6 rods etc. Sometimes you get great ones but it's a matter of luck as to who the supplier is at the time.

You may struggle get it to run with a 6013, the rod doesn't deposit enough metal for the rate of burn, when I used to show students this party trick we used iron powder electrodes,

Sorry, I was answering Windy Miller's post on what his 140a buzz box is capable of.

I always buy Oerlikon 6013's to use with the buzz box I have a few 7018's but its all but impossible to strike the arc with them. They work ok when I use them with the TIG though. I was given a half full white box the other day (6013) but I've not tried them yet. I'm assured that they're as good as Oerlikons, but time will tell!

 

[Bill Edwards]

7018 rods need to be DC (which the TIG will be) or high voltage AC (which is usually on oil cooled welders with a high volt range). No chance with a buzz box!

What a waste of a rod and material ! Just a quick running it !
Party trick me thinks !!
