Bush Welding

Bush Welding

Set yourself up a bush welding kit using the list below, and you’ll never have to buy a beer again once your mates need some trackside repairs.

  • Set of heavy duty jumper leads with sturdy battery clamps
  • Connecting cable to link two batteries in series
  • Set of welding rods, general purpose, wrapped and kept clean and dry
  • Welding goggles or mask
  • Chipping hammer or similar
  • Fire extinguisher
  • Suitable attire and gloves
  • A variety of metal pieces.

Here’s our podcast on Bush Welding with more information on achieving a successful repair in the Outback when travelling.

It might sound like we’re combining backyard mechanics with lava hot spanners, but it’s important to consider these few tips before you start.

Firstly, it is significantly more dangerous than standard workshop welding, so extra precautions are required. When using batteries near lots of sparks and extreme heat means safe practices must be employed at all times. Plus you don’t want to light up the bush either.

Secondly, it is usually in more difficult circumstances and materials may have to be scavenged to effect a repair, so a few practice sessions in the garage before that big adventure might give you a better chance of a successful outcome.

Lastly, it should only ever be considered an emergency repair, so don’t forget to review and undertake a complete repair process at the first opportunity.

So aside from the three tips, the rest is just regular welding with a stick just like arc welding at home or work. If you are not familiar with welding, then take heed of tip #2 and practice, practice, practice.

One of our listeners has commented below “U should have shown a photo of how both batteries are used as the power supply in the way they are connected to wat u are wielding so the negative goes to the plate steel and the positive goes to the welding rod shown as 1photo” Sorry, no picture but thanks for advising us and supplying this info.

    welding with batteries can be very dangerous they give off hydrogen gassed take my word it leaves sulphuric acid and battery bits every where

    When welding like this, positive to the piece will create more heat and deeper penetration with less weld width, where negative to the piece will mean less penetration and wider weld width.
    As a guide negative to the hand piece for heavier materials and positive for light materials.
    Positive to the hand piece is usually slightly easier to weld with as more heat is generated at the welding rod, rather than the piece being welded.
