i have a similar machine
i love it!! the water resevoir is actually in the base of the machine i have and circulates thru a built in cooler then to the torch
mine has arc welding capibility built into the front of the machine ..u just plug in ur tweeco connectors to the ground and stinger and turn off the high freq, which is built into the machine also and use it just like a regular welder
there are different percentage tungstane in your electrodes that you have to learn what percents are for what materials and also when to sharpen the tungstane or ball it as it is called..
it is the easiest of all the welding procedures to me , if you can fusion weld with a regular oxy/acetylene torch then the tig will be a snap,
its pretty much the same except you are using an electric torch and plus you have the advantage of a shield gas over your molten puddle which is real easy to see because unlike an arc welder you don't have to learn what is your puddle and what the liquid slag is...i'm serious it is the easiest of all the welding techniques, espescially if you have the foot control where you can actually vary the intensity of your arc with the foot pedal
sort of like a sewing machine pedal you barely push it and the machine goes real slow and you push it all the way down and the machine goes faster and it is variable inbetween..well if you have the foot pedal for the tig it works the same when your puddle starts to get to hot and want to drop thru you can use the heel of your foot to back off the arc and vice versa when you start you can have it wide open to establish the arc and then ease the pedal back to a cooler setting as you weld
i promise you, once you try it and see what i mean you will understand it, honestly it is the easiest to weld with, now learning to walk the cup is a different story...you have to learn to rotate your wrist while at the same time raising and lowering ur elbow and you can actually put the ceramic cup on you material and make it walk real precise circles and make your weld look like a row of dimes......i never have understood why people make such a big deal about the tig torch because if you can weld,...just a little practice and you will want to weld everthing with it!
on aluminum it is a little harder because it gives no warning as to when it is about to fall thru on you, like on carbon or stainless steel you can see the puddle start to dip in about to fall out and make a hole, aluminum won't do this just poof! hole but once you get the hang of it you will be singing the same tune about how easy it is
