My smallest Victor tip is 0, and it's not small enough. What size do I want to use on .041" brass without burning holes in it?
Steve...what are you really trying to do?
Is there not something with less heat that will work? MAPP? Propane?
Propane/oxygen works with the same equipment, not as hot as acetylene. Dave in Bellingham, wa
Use less Oxygen and Acetylene, keep the flame low...
also keep your distance, it should work just fine..
I need to fill a hole in one of these and attach some hardware to the back. I'll try the lower heat suggestion on a practice piece.
Steve, cut back the pressure on your regulators too, that will decrease the heat a lot. Makes it easier to adjust for what you need. Dave
Steve, I would use silver solder and just keep the heat source back a little. It is imperative you use the correct flux and everything must be very clean!!!!! When you go to re-polish it, it will blend perfectly.
My welding tips for the day is one: be careful to not point the flame anywhere near flammable materials, and two: never ever point the flame toward your fingers.
Bob, any silver solder that I have used is silver in color. I do know that there are some that look a lot like brass, but not all do. JMHO Dave
By the way Steve, a 00 and a 000 tip can come in handy. Look for them at a swap meet, they show up from time to time. Dave
For what's it worth I soldered a new neck on the older flat tube radiator in my 21 T with a hand held propane torch. Worked great with a smooth joint all the way around and no burning of the nickel plating.
When trying to solder thin material with a oxy-acetelyne torch use a low neutral flame with the flame off or away from the material as much as possible. Use the smallest tip you can find. Remember that the heat from the flame does the job not the flame itself. That's how I think of it. Welders will have have different viewpoints about this. After 40-50 years that's what works for me when using a torch to solder.
IMHO, the 000 tip is a hobbyist's friend!
I used a butane pencil torch o work with brass with thicknesses from .005 to .040 with silver solder.
