If the welds haven't been painted over yet no need for wire brush just crank the Tig up and away you go , but you need gas for a Tig as well .
Other option is oxy acetylene if you can borrow or have a set .

Thanx mate.
I remember you gave me some good advice regarding TIG last time. I have a DC TIG machine. I'm yet to acquire an AC one(which is a one I want badly for my aluminium projects :) ). I don't have a bottle yet either, but I've been working on getting a good AC TIG machine first. With the troll giving me craps, things to do with TIG welding got put off. Now I'm getting back to it.
It's pretty hard to arc weld thin pipes with paint on it without blowing holes on them mate(when I don't have enough experience with that). And it's even harder when I have to weld two different thickness & two different types of steel(one being gal and one being powder coated or rusted. I discovered even the painted/powder coated pieces were gal, so I had to deal with lot of toxic fumes & wear the hanky over my nose :)). So, it took me ridiculous amount of time to weld the thing. I purposely put extra weld beads on top of each other to strengthen the seemingly weak beads(of course, that's not good practice :) )
I bought a chunk of el cheapo arc sticks(2.5mm 6013) that is not so good even with the inverter welder, but had to use them up.
Find a 3 year old to throw some glitter at those welds and own it like a boss!!
Cold-gal in a can is always a good choice 😎
