Re: Hand pump
Your advice is incorrect and dangerous.
1. There is chemicaly NO difference between welding oxygen and medical oxygen both can be a hazardous gas to handle and you do not want to fill balloons with it.
2. You have confused flow as in how much air is shifted with the pressure (force per unit area is delivered. You are correct in that a small compressor is pants for blowing up balloons because it has a very low flow rate but can easly get up to 180 times the pressure to burst an 18" balloon or 45 time the pressure to pop a hot water bottle.
If you are wanting a cheap fast pump go to a large builders mercants and buy a wet and dry vacum cleaner, most can blow and use it only for balloons.
