Step 3: Assembling the Torch

1) The bare torch

2) Screw the correct size collet holder into place on the front of the torch (the end with the white stripe).  The rounded end of the collet holder should be pointing forward.

3) Slide the correct size collet into the back end of the torch.  Insert the collet with the slotted end facing forward so that the rounded edge of the collet meets the rounded edge of the collet holder.

4) Screw the back end cap onto the back end of the torch (the end WITHOUT the white stripe).  Be careful to avoid cross threading as the back end cap threads are made of a harder material than the internals of the torch.  You may be charged for damage to the torch if you are deemed responsible.

5) Screw the gas cup onto the collet holder.  The rounded end of the gas cup should make contact with the white stripe on the TIG torch.

6) Insert the correct size and type of tungsten into the torch.  See notes below.

7) The radius of the opening of the gas cup designates your tungsten stick out.  If the opening of the gas cup is 1/4", your tungsten should stick 1/8".

-Make sure to use the GOLD band tungsten for AC welding and ORANGE band tungsten for DC welding applications.

-AC welding does not require that you grind your tungsten.  If you leave a square edge on the end of the tungsten it will turn into a ball during AC welding.
-for DC welding, make sure that all of your grinding marks are running in the same direction--parallel to the tungsten-- in a straight line.  The length of the cone (the section that is ground to a point) should be double the diameter of the tungsten.

-the collet and collet holder need to be the same size as your tungsten.
<p>I need suggestion regarding this problem going on in my company.In my company they need some simple set up for TIG welding to weld the upper small part shown in picture on Candy cane part,I need the best Idea for simple set up for the TIG welding that any operator can do it n would work perfectly.Company has very few part in this order so that they don wanna spend much money for Robotics or any CNC work.All I need is a better Idea (you can show in rough drawing hand made). </p><p>Here in second and forth pic I have shown the table they used to hold the pipe tightly while welding but it isnt perfect also in third pic it was a set up for some other welding part that we can used it if necessary.</p><p>Please help me Asap,its urgent .</p>
should look into using a ball flow regulator instead of guages. so u can get a better understanding gas flow
smart way of doing things
u might wanna repair that tig torch tho
not always tho depending the thickness of yr metal tho. 1in. plate will be a better heat sink than a 1/4 in. plate.
Just took the SBU at Menlo Park with you and have a question, When using the slide calculator does using a V-groove on the weld effect the values used for metal thickness?
It does affect the amperage. Lets say you were doing a butt weld on 1/4&quot; steel that had a V groove. Your first pass would require less heat than your last pass because on your last pass there will be more metal in the joint. <br> <br>Hope that helps!
