There are many different types of power cables including Welding cable, DLO (locomotive), Type W, Type G-GC and Stage lighting (Entertainment Cable). These are all made with a rubber neoprene jacket, but they each have differences in insulation thickness and application. This article will explain the differences and help you understand how each cable is used.
Welding Cable is the most basic because it

There realy isn't a "two phase". There is single phase that has a neutral wire – sometimes called "split phase".
If you only have 3 phase available, they you may have a problem trying to get 240 volts for a welder. You may need a transformer for this.
The machine was never intended for such usage.

It's possible you do not own the tanks. Some companies rent the filled container to the customer and retain ownership of the container. Check there is no supplier name on them. If there is ring them and find out how they supply.
That's more than likely the distributor, not the manufacurer.
Lincoln is probably the actual manufacturer.
you may want to do a search on that (google). That may give u the help u need. Good luck!
In general, heat-treated mild steels are arc welded without pre-heat. However, a preheat should be used when the metal temperature is below about 50 degrees F (10 degrees C), and a preheat of about 100 degrees F (38 degrees C) or higher should be used if the plate thickness is over 1 in. (25.4 mm) or if the joint is highly restrained.
Welding supply will have compressed nitrogen but never liquid nitrogen.
Try a machine shop that works with soft rubber products.
They use the liquid nitrogen to harden the rubber so they can machine it accurately with out it stretching all over the place.
