Do you have a gas welder? You might need to reduce the thickness of of what you weld a bit, but it would be better than not welding at all.

no tom no gas just a small propane setup .to have oxy acet here costs 200 per yr hire for each medium bottle and about 90 to 110 each for the gas ...propane is 35 dollars for a 20 kilo bottle to fill so for me being on a disability pension its way to expensive to have gas bottles .I learnt to oxy weld back in 06s off my dad an stick welding too .apparently if I hold the handle away from me an don't have anything over a 100 amp mig I should be ok lol I have a 200 amp mig but my son is happy to do what I ask of him .I been blessed with 2 sons 29/30 both have 2 trade licenses an both are switched on with mechanical an fabrication as when they were little like 6 yr old id get old lawn mowers an taught them how to fix ect . my youngest used to work in a Harley shop when he was 13 after school an weekends so when or if I had a problem with one of my bikes id let him have a go fixing it .recon I done a good job with them I was a single parent from 1988 so I either done good or was just lucky to have 2 of the most respectfull young men I have met in my life .




thanks for the picture info too fellas


I got a question but will post it on Thursday it a gooden an has me racking my brain so you lot should be able to help easy as
cheers

I know a guy in Florida that builds smokers and BBQs from old propane tanks. All he uses for welding is propane with compressed air.

id be interested in finding out how he sets up his propane an air from compressor .im told that oxy in the bottle is pure or something like that vinny .and it makes for a way more hotter flame than compressor oxy .

[Vinny]

He got everything he needed (except for the compressor, which he already had) from a propane dealer that he happened to work at. I know when I worked at a radiator shop, they used natural gas and compressed air for radiator repair. Everything they used (torchwise) was available at any of the local welding supply shops. You can probably find the stuff for doing propane/air welding at a welding shop too.

I guess it depends on your definition of "welding". There are several different torch sets made to use different fuels in combination with "air". Not to be confused with (pure) Oxygen. The Fuel/Air combinations are generally used for brazing/soldering work because of their reduced flame temperatures, compared to Fuel/Oxygen torches.

I have a full size set of Oxygen/Acetylene torches for "welding" & cutting, but I also have an Acetylene/Air torch rig that is much more portable for brazing/soldering work. There may be exceptions but every radiator or condenser/evaporator coil I have ever seen was assembled with a soldering or brazing operation. I've never seen one myself that was welded together. Most A/C or refrigeration line sets are brazed together with a 15% silver/copper/phosphorous filler rod. (1190° - 1475° F)

Just about every plumber or HVAC tech I know of carries either a very small portable Oxy/Acetylene rig or a Fuel/Air torch set on the truck. Or both.

thanx highpower I had a look at the compressor propane setup here a while ago and came to the opinion that there would be to many contaminants in the air from the tank .that being said itd still be a great idea so I can braze /silver solder ect .I have watched toms video on joining blades a few times an got some silver solder from a mate round the cnr .the blades for my saw [similar to hf 4x7 ]are 35 dollars here .seems Australia is the dearest place to be if you want good tools and toys ive seen the same/similar bandsaw over the pond for under 200 mine was just under 700 with a mates rate

ive got some brazeing to do on a old WLA frame [they brazed them back then] an will try the air propane setup
in the welding stores ect here al they sell is the tips for propane / oxybottle seems everyone else must be richer than me lol
