| Ever wish you could find some simple Instructions for tig welding? Like boiled down Tig welding basics without all the Techno babble?
This is about as simple as it gets without photos... Tig Welding Machines Settings - For [url=http://www.orlando-apts.com/nfljerseys/]cheap nike nfl jerseys[/url] Steel, stainless steel, nickel alloys, and pretty much anything except aluminum, and magnesium, your tig welding machine will be set to DCEN (direct current electrode negative) aka Straight polarity. High frequency [url=http://www.getconversational.com]hollister france[/url] is set to start (on newer inverters this setting is built in). Postflow is set to at least 10 seconds, A/C balance if equipped is set to the DCEN default setting. Contactor and amperage switches are both set to remote. (again on newer inverters, this is default when the tig mode is set). For tig welding aluminum, set polarity to A/C, A/c balance to around 7, high frequency to continuous. All other machine settings above are same as for tig welding steel. Shielding gas - set to around 15 cfh. Argon is the all purpose shielding gas for tig welding anything. Once you get some seat [url=http://www.seattlesoycandles.com]hollister france[/url] time, you may want some 50/50 [url=http://www.achbanker.com/home.php]www.achbanker.com/home.php[/url] argon/helium for tig welding aluminum. Tig Torch - There are air cooled tig torches and water cooled. And there are big ones and little ones of each. Generally speaking, smaller is better. A water cooled 250 amp tig torch is smaller than some 100 amp air cooled torches. Bigger torches are ok, just harder to manipulate in tight spots. A #7 tig cup is a good place to start. Tungsten Electrodes - For welding steel, electrodes need to be sharp and clean. A belt sander, or 4 /12 inch sander will be fine. For aluminum tig welding, just round the tip with a sander and thats all. 2% thoriated tungsten electrodes will weld everything. Thorium is radioactive so if that scares you, get some 2% lanthanated and it will work for everything. Use the smallest electrode that will get the job done within reason. 1/16 tungsten electrodes are good up to around 90 amps, much [url=http://www.achbanker.com/home.php]hollister[/url] above [url=http://www.lcdmo.com/hollister.php]hollister france[/url] 90 amps and you need 3/32. Above 200 amps and you need a 1/8 tungsten. Tig Welding Rod - 90 % of everything you will tig weld can be welded with 3 different tig rods. 308 for welding stainless, E70S2 - for welding mild steel and 4130, and 4043 for welding aluminum. There are [url=http://www.orlando-apts.com/nfljerseys/]cheap nfl jerseys[/url] all kinds of rods for specific applications but these 3 rods will handle most of the tig jobs you will do. Tig Welding Technique - Hold the tig torch like it was a first grade pencil with the ball of you hand resting on the table or something. Lean the torch back just about 10 degrees and with the tip of the tungsten lifted about 1/4 inch off the metal, nod your welding helmet down and press the foot pedal. Once you establish the arc, increase the heat by pressing the foot pedal until your [url=http://www.rtnagel.com/airjordan.php]nike air jordan pas cher[/url] welding puddle is about 4 times the thickness you are welding up to about 3/8 inch max. Try to [url=http://www.gotprintsigns.com/monclerpascher/]doudoune moncler pas cher[/url] keep the arc length (distance between tip of electrode and puddle) to about the size of the electrode you are using. Now comes the technique...to get an evenly rippled stack of dimes welding bead, add filler rod, pause, move the puddle about 1/8 inch and pause, add filler metal, pause, and so on, and so on. If you do this step and pause tig welding technique right, you get a uniform stack of dime bead. Easy right? But it takes lots of practice and seat time. 5 Tig Welding Tips: - Try to maintain [url=http://www.gotprintsigns.com/hollisterpascher/]hollister[/url] an tip to puddle distance of no more than the electrode diameter. - Keep torch angle to a 10 degree maximum. - If the filler [url=http://www.vivid-host.com/barbour.htm]barbour uk outlet[/url] rod balls up and tries to [url=http://www.mansmanifesto.com]www.mansmanifesto.com[/url] blob into the puddle, see tips 1 and 2 above. - For steel, keep plenty of sharp electrodes handy and change electrodes when you dip your wick. - Get some E70S2, ER308, and 4043 aluminum rods. These 3 will do most tig jobs. The Tig welding tips in this article didn't help you improve your skills then you may need to go back to school to learn the basics. This part is important so pay attention. Here is some info you need to know if you're serious about learning how to walk the cup.
