Liquid nitrogen can be purchased from specialty gas supply companies, welding supply stores, or scientific equipment suppliers. It should be handled with caution, as it is extremely cold and can cause frostbite upon contact with skin.
In plastic welding, equipment used includes plastic welders (some are ultrasonic) and as with any type of welding, protective equipment such as gloves.
ER70S-6 is a very common filler metal when welding with Gas Metal Arc Welding or Gas Tungsten Arc Welding on a low carbon steel (mild steel). This can be purchased as a spool or in rod form.

One limitation of gas welding is the limited range of materials for which it is suitable, as it may not work well with certain metals or thicknesses. Additionally, gas welding can result in slower welding speeds compared to other methods like arc welding. Maintaining the proper gas pressure and flow during gas welding can also be challenging.
A Speedglas welding helmet can be purchased at various retailers online. One can purchase a Speedglas welding helmet online at websites such as Amazon and eBay.
Gas pressures and flow rates are typically determined based on the type of material being welded, the welding process, and the size of the weld joint. For example, when welding aluminum, higher gas flow rates and pressures may be required compared to welding steel due to its higher thermal conductivity. It is important to consult welding procedure specifications and guidelines provided by the welding equipment manufacturer to determine the appropriate gas settings for different materials.

Praxair is a manufacturer of welding equipment and welding supplies. They are also a supplier of industrial gases as specialist equipment, such as helium and hydrogen.
To gas weld, you'll need a gas welding torch that mixes fuel gas with oxygen to create a flame. The workpiece is heated with the flame until it reaches the melting point, and a filler rod is added to create a bond between the two pieces. Practice and proper safety equipment are essential for successful gas welding.
The most important equipment you can have is your safety equipment, your gloves, visor and heavy-duty clothing. You have to have some sort of a power source to generate the electricity necessary for arc welding, so I'd say a power source is your most important arc welding equipment.
