Learning how to weld is really not that difficult. Most welders learn arc welding first. The easiest way to start welding is simply by practicing. You can pickup a cheap arc welder from somewhere like harborfreight tools. It will cost you under $120.
You will also need a welding helmet, welding gloves, a heavy jacket and some welding rods. Take my advice, spend the extra money and get an auto darkening helmet. It will make learning so much easier. You will also want to get a supply of scrap steel to practice on. This can be picked up at a scrap yard.
Now that you have all the supplies, its time to weld. Find an appropriate area, somewhere outdoors, without anything flammable around. Secure your scrap steel to some kind of table at a comfortable working height. Attach the ground to the steel. Place the welding rod in the other clamp. Put on your heavy jacket, gloves, helmet and thick pants. Turn on the welder, set it at somewhere around 80 amps to start with.
To start the arc you want to jab the electrode at the steel, then slightly pull back. If it sticks, break it free and try again. If it continues to stick, turn the amps up.
Once you have an arc going you will need to feed the electrode into it to maintain the arc. You want it about 1/4 of an inch from the metal. When it is at the right distance it will make a crackling noise. If it is too far away it will be more of a popping noise, with sparks and metal flying in all directions. If it is too close, it will stick to the metal.
The first thing you want to practice is simply laying a bead on a single piece of metal. Once you have that down, you can move on to connecting two pieces of metal together.
Remember, when learning how to weld safety comes first! You can instantly cause permament eye damage from looking at the arc without a helmet on. Also welding fumes are highly toxic. Be sure any bystanders are aware of this.
If you are interested in learning welding as a career or a hobby, “The Welding
Bible” is an excellent resource. It explains in detail everything you need to go from beginner to pro.

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.

That's more than likely the distributor, not the manufacurer.
Lincoln is probably the actual manufacturer.
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.
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.
around 300 watts.
