Hi All

Does anyone know if you can buy mini gas tanks for welding?
I am looking for something portable, that i could use while up a ladder.

I was thinking of some sort of handheld type set up similar to a blow torch but am not sure if thats possible so some sort of mini 1kg type tanks and perhaps a long hose might work?

What do you guys reckon i should look at?

Gas is usually only one component with welding, are you meaning brazing or soldering?

Looks like you need soldering rather than welding.
What metal are you going to work on? Copper or steel?

I have a 15m retractable hose reel set up on my oxy acetylene and oxy LPG tanks.
Allows me to do cutting, heating, brazing at a distance from my tanks..
Don't do much gas welding though.

Steel to Steel
Basically trying to weld? angle iron to NB32 pipe

The pole is starting to flex at the top in the wind (its 5 metres high) and I fear that my welds with the little Mitre 10 electric welder are not going to be able to withstand the constant flexing.

So I want to get up on a ladder and put about 25 more angle iron links between the poles to make it much more sturdy.

There is about 500kg of concrete holding it into the ground so I cant bring it back down off the hill

Petrol powered electric welder perhaps?

Dynamic: Petrol powered electric welder perhaps?

Pop down to your local hire shop see if you can rent a larger diesel/petrol mig with a hand spool.
Make sure you get long enough cables with it!
As a bonus it'll have a power outlet so you can run a grinder to prep and finish your welds.
Wire feed issues limit normal mig cables to 3-4m
I used to have one runnig off the PTO on my tractor with a separate wire feed.
It was useful for welding stuff on beaches, mountaintops, swamps.
What's access like to your site? Is that galv steel?

Yes galv steel, coated with about 5 coats of cold galv spray factor 72 and another 3 coats of factor 60
I can get the car to the site, with a little difficulty.
I can get the quad bike up with no problem.
But no trailer.

So the machine would need to fit in my mid size SUV with the seats down.

This is what I used:

I have a battery powered angle grinder and I suppose if i can get a decently powered petrol one or something much better than the little M10 machine then that would be awesome.
