When welding with a 3 tip what should the oxygen and acetylene be set at?

If you set your tanks to about 5 psi and 5psi, you should not have to change the pressure, instead simply adjust the knobs on the torch to give more of each gas. If this still is a problem, try 7-9 psi for each. NEVER NEVER NEVER go above 12 for acetylene, it is unstable at 15, best to not get close...

Are these gas dangerous or not oxygen?
Strangely enough, pure oxygen is very dangerous. I was helping a mechanic work on my truck once. He was using an oxyacetylene torch. When you use one of those, you turn the oxygen on after the acetylene is lit, and turn the oxygen off before turning off the acetylene. He turned the acetylene off first and accidentally sprayed my greased fifth wheel with pure oxygen. The oxygen reacted with the grease and set it on fire. The reason I was there was to operate the shop's huge fire extinguisher; we got the fire put out quickly.
What should the welding machine be set at for a 7018 welding rod in 3G?
That depends on the diameter of the rod if it is 1/8" set your amperage between 125 and 140.
What is Welding process?
There is no BEST process for all conditions/situations/materials/applications. Easiest to use would probably be GMAW (MIG welding). Most useful for all applications and metals including cutting OAW (Oxy-Acetylene welding) usually referred a to as Oxy-Fuel. Most widely used process is probably SMAW (stick welding) which would also be most portable and cheapest to purchase. GTAW (TIG/Heliarc) is used mostly indoors on thinner and or non ferrous metals ( Aluminum, Stainless Steel, and most alloys. If I were to set up a shop at home I would consider a DC stick welding machine (preferably a rectifier type) and an Oxy-Acetylene setup.

What should the welding machine be set at for a 6010 welding rod?
it dependsif your going virticle down i would set it at about 100 amps but if your going flat or horizontal i would crank it up to about 125 amps
How can you select the current values for welding?
The amount of current (amps) is controlled by the user. It's done with a variable resistor. Another thing to note is whether you are welding constant current or constant voltage. If you are welding constant current, the voltage will vary and a set Amp measure will remain constant. With constant voltage, the current will vary and that's determined by the resistance. Constant voltage should be an easier set up. I'm not 100% sure but most stick welding is constant current, which is why increasing the arc length produces more heat, because more arc length should increase the resistance, which would cause the welding machine to increase voltage to keep the current constant.
True or false current is set too low or too high you should change the settings during welding?
I was always told not to so I say false.
What is the three dimensional shape for acetylene?
A set of atoms in a straight line - with the two hydrogens on the outside and the two carbons in the middle.
How do you set up a welding rectifier?
A rectifier is a type of welding machine. Fairly new development that changes common electrical supplies to voltage and amperage that can be used to weld. It uses less electricity than standard welding machines (usually transformers). It will require a certain supply (voltage - amperage) that you connect the machine to and should state the minimum requirements somewhere on the machine.
How do you Weld with a cutting torch?
You turn on the Acetylene and ignite it, you start to add oxygen via the control valve. You will see the colour changes from yellow to blue. There are two shades of blue, one is slightly darker than the other. Once the inner blue cone is down to a nice roaring bright light you are more or less set up to weld. Get your Filler wire (welding rod) put on your welding goggles and lower the flame to the piece of metal you wish to weld. You will start to see the metal heat and become molten. The next part takes practice. Once the metal has turned molten immediately start to add the filler wire; keeping the torch at about 45º move along the metal adding the wire at a constant steady rate. Insufficient filler wire will result in either undercut or the pool dropping through. Too much wire or moving to fast will result in either a poor weld or no weld at all. Speed and angles do not need to be 100% correct find what is comfortable for you. Remember Gas welding is Extremely Dangerous and you should take courses in it before attempting it. I will add a couple of links for you to get a more detailed idea lower in the page under related, source links.
How can you reduce spatters in welding process?
by having the machine properly set and good consumables.
Management of welding materials in space frame company?
Acceptance of welding materials The quality of welding materials must meet relevant standards. Before the welding materials are put into the warehouse, the warehouse management shall first verify whether the following relevant materials are complete, otherwise they shall not be put into the warehouse, and the materials shall be properly kept for future reference. ①Qualification certificate of welding materials ② Brand and mark of welding materials ③Batch number, specification and quantity of welding materials The material manager is responsible for the appearance inspection and re-inspection of the welding materials, and the unqualified products shall not be put into the warehouse. Storage of welding materials The storage of welding materials is mainly to prevent the corrosion of the welding wire and the steel core of the welding rod, and to prevent the coating of the welding rod as well from being damp, deteriorated, or even falling off, thus affecting normal use. The drying of the normally stored welding rod, welding tip, flux and flux-cored wire before use is an important part of welding quality management. 1.The space frame company that uses welding rods should set up a special welding material warehouse. The welding rods, welding wires, fluxes and welding tips should be stored in a dry, well-ventilated place and kept by a dedicated person. 2.Thermometers and dehumidifiers should be installed in the welding material warehouse. The indoor temperature should not be lower than 5℃, the relative humidity should not be higher than 60℃, and the ventilation should be good. 3.Dedicated drying box and constant temperature box should be installed in the warehouse. 4.Eye-catching baking specifications should be hung in the warehouse, and management personnel should strictly follow the specifications 5.Welding management personnel shall establish accounts and mark the cards according to classification, brand number, specification, and batch number, and ensure that the accounts, cards, and objects are consistent. 6.Welding materials must not be stacked on the spot, and should be more than 20 mm away from the ground and 300 mm away from the wall 7.Special attention should be paid to the environmental humidity in the storage of welding rods 8.The higher the relative humidity and temperature in the air, the higher the partial pressure of water vapor, and the easier it is for the skin to absorb moisture. It is generally recommended that the relative humidity in the air be less than 60%, and a certain distance (about 20 cm) away from the ground and walls. The temperature is preferably 10 to 25°C. 9.The drying temperature of low-hydrogen electrode should be 350-380℃, and the holding time should be 1.5-2h. After drying, it should be slowly cooled and placed in an incubator at 110-120℃ for storage and use; In the insulation cylinder; if the dried low-hydrogen electrode is placed in the atmosphere for more than 4 hours, it should be re-dried; the number of repeated drying of the electrode cannot exceed twice; the damp electrode cannot be used. 10.Welding rods, welding tips, fluxes and flux-cored welding wires must be dried in accordance with the product manual and relevant process documents before use. 11.The heating, temperature measurement and temperature control performance of the welding rod, flux drying device and heat preservation device should meet the requirements of use. 12.Distinguish the type and specification of the electrode, and it can't be misused. 13.In the process of welding rod transportation and the other party, always pay attention not to damage the coating and the other party should not be too high. We should be more careful about welding rods with poor coating strength.
