As a rookie tig weldor who has only recently started to be decent I can offer these tips that worked well for me. Don't drink too much coffee before you weld. If you have a tendency to get low blood sugar and the consequent "shakes" snack on stuff throughout the day. Spend as much time as you need manipulating your work, your torch hose(especially if it is a stiff air cooled hose), your hands, your feet, your elbows to get comfortable. I have found certain positions that are very good for seeing the joint, feeding the wire etc., yet muscle fatigue quickly sets in and you get the shakes. experiment with where your foot is placed on the pedal. I have found that if the pivot on the pedal is just on the front of my heel, I have the smoothest control. When the pivot is too far forward, under the arch of my foot, my foot shakes when i try to steadily back off the heat. I have a range of blocks and scrap of different heights that I use to rest my hands on for different sizes of work. Even the pros use improvised rests (see cover of the Jan. welding journal) . I tried the method mentioned above about feeding the wire without using the torch to get the feel for it. Unfortunately it is hard to really replicate the true hand motion of feeding, because when you weld, the rod is always melting off. If you feed the rod alone, pretty soon you've got a whole bunch of rod sticking out, the end starts getting heavier, and it's really an unrealistic practice. The thing you need to teach that hand is to feed the rod accurately into the edge of the puddle, WITHOUT touching the tungsten, and without removing the hot tip of the rod from the warm, comforting bosom of the inert gas envelope. It's a pretty tall order for your brain when you are already trying to control your torch angle, lead angle, arc length, travel speed, and amperage. When welding on work I have just spent hours cutting and fitting, work that absolutely needs to be done right, I will sit down at the table, breathe deep, relax, think mellow thoughts....and then start my arc, jam the tungsten so far into the puddle that I break off the whole tip, curse loudly and profusely, and then calmly unscrew the back cap, pull out the tungsten and think "I Love Welding"
