Stainless Steel

Cups should ideally be 4 to 6 times the size of the electrode The length of the taper on the tungsten tip should be two to three times the diameter of the tungsten. To safely hold tungsten electrodes for sharpening with a grinder, insert them into the chuck of a drill. Running the drill while sharpening the tungsten ensures a uniform point. Move the tungsten across the wheel to prevent grooves in the wheel edge.

Tungsten Electrodes

Pure Tungsten - EWP -- Used primarily for AC welding of aluminum and magnesium at low currents. The tip of the tungsten must be balled before using. Pure tungsten also provides good arc stability for AC sine wave welding, especially on aluminum and magnesium. It is not typically used for DC welding because it does not provide the strong arc starts associated with thoriated or ceriated electrodes.(ISO = W)

Lanthanated 1.5% - EWla-1.5 --General purpose electrode used for steel and stainless steel at a wide range of currents. Often used as a cheaper, safer substitute for high-priced thoriated tungsten. (ISO = WL15)

Ceriated 2% - EWTh-2 -- Can achieve high currents with good arc stability. Another substitute for thoriated tungsten. Best used to weld carbon steel, stainless steel, nickel alloys, and titanium(ISO = WC20)

Thoriated 2% - EWTh-2 -- An expensive and radioactive metal. Use care in grinding (i.e. wear a dust mask), keep your skin covered and avoid contact with the metal when it's heated. These electrodes are used mainly for specialty AC welding (such as thin-gauge aluminum and material less than 0.060 inch) and DC welding, either electrode negative or straight polarity, on carbon steel, stainless steel, nickel, and titanium.(ISO = WT20)

Zirconiated 2% - EWZr-2 -- Another option for AC welding, zirconium is preferred in situations where resistence to contamination is paramount. The tip of the tungsten is balled before using. NOT FOR DC (ISO = WZ3)

MY TIG WELDER
The device has a connection to the water cooler, this cooler is available in our shop. The tube package can also be water cooled. If you prefer, welder and tube package work without a water cooler also perfect. Pulse function: more power without increasing the temperature of the material substantially, preventing the combustion of the workpiece. 2 Stroke and 4 Stroke circuit: at 2-stroke, the torch button of the TIG tube package has to remain pressed and held. Once the button is released the arc is extinguished. At 4-stroke the arc remains stable after pressing. Only by pressing the torch button the arc is extinguished and the current reduction occurs automatically with the gas-run time. Professional settings in which you achieve results of a quality that impress even the professional user. Antistick: prevents annealing of the electrode (less consumable electrodes), because the power is immediately terminated. Hot Start: automatic voltage increase at the start HF Ignition: high-frequency contactless ignition to the workpiece. MMA: manual metal arc welding. TIG tube package with ball joint and with integrated control switch (water cooled). Adjustable welding current: adjustable between 0 and 315 A (for pulse mode upper value). Automatic slow current reduction after switching off the tube package. Adjustable between 0 - 10 seconds (makes a clean finish, there are no blowholes). Gas preliminary time: important to protect the weld from air supply and to create a gas atmosphere Gas post flow time: saves the tungsten electrode against excessive wea. and protects the weld from oxidation. Gas magnetic valve: will open only when pressing the hand torch or the foot pedal and closes when the welding process is completed. Welding with pulsing: penetrates deeper into the workpiece Pulse frequency: adjustable between 0,5 - 300 Hz Pulse current: adjustable between 10 % - 90 % Pulse intensity of welding current: adjustable between 20% -60% Spray arc circuit: MMA-Mode (stoving improved, more stable arc) Automatic cooling ventilators. Overheating protection: turns on when the device is overloaded. A red control light turns on, and goes off when the device is cooled. Current shift: only for aluminum welding of importance. AC welding causes a shift of the current to positive or negative wave motion of the current

He says for foot pedal up the StartA and WaldingA by 20 Start Amps - Ramping upwards, allows for a really low amperage startup or a hot one. (not used with pedal) Welding Amps - peak amps Background Amps -Background current is the low current of the pulse. Down Amps -allows the current to decrease at whatever rate you set on the knob so that you wont leave a defect like a fish eye or crater crack (not used with pedal) Pulse - pps or pulses per second…, 'Hz' how fast the pulses happen per second., you might think that once you get above 30 pps it would be like no pulse at all…you would be wrong. Higher pulse rates really focus the arc. Pulse Width - This is the percentage of time the current stays on the high side of the pulse. For starters, I recommend 30-50 percent...if you go much lower than 30, it just limits your heat too much and you wind up just giving it more foot pedal to compensate. Post Flow - the length of time the torch gas flows after the arc terminates. Ac Balance - Syncrowave technology gives you the ability to set balance control on range from 0 to 10, or maximum cleaning to maximum penetration - • 2t ---for using a switch on the torch handle…when you plug in the foot pedal or torch amperage control, most tig inverters are designed to bypass the 2t and 4t settings because the amperage control overrides all the upslope and downslope stuff. The 2t setting pretty much turns the torch switch into a 2 position switch. Press the switch , you get and arc. Let off the switch, arc goes out. • 4t—the 4t position is most always used in conjuction with upslope and downslope settings…something like this… o press the button and you get an arc. o Let off the button and the arc upslopes to whatever the main aperage is set to o Weld o Press the button and arc downslopes to lower amperage o Let off the button and arc quits. o Some machines are different but this is the general principle of 4t operation
2t / 4t settings explained
 The typical TIG rig will have three main electricity options - AC, DCEP, and DCEN. AC is for aluminum <- MY MACHINE DCEN means "DC, Electrode Negative", and is for welding steel. <-- my MACHINE DCEP means "DC, Electrode Postive". This setting is used for balling the tungsten tip, or stick welding. The reason you would deliberately ball up your tunsten to to weld aluminium (on AC setting). To do this you make a weld only for a second and the end will ball up and then you switch to AC. HOWEVER "You only need to ball your Tungsten if you are using a transformer machine. If you are using a new inverter style welder go ahead and leave a point on your Tungsten. MINE machine is an INVERTER style so no need to ball. <- NO SETTING ON MY MACHINE FOR THIS OPTION. MY MACHINE Electrode Negative WELDING ALUMINIUM On my machine, no need to ball tungsten tig. Just leave it sharp as normal. Prep: wipe down with acetone. SELECT AC Select SQUARE WAVE (this create a "cleaning" effect by breaking throughthe oxide layer). Strike arc, when you see a puddle, move and add filler infront of puddle At end , add some extra filler otherwise a crater will form and lead to cracking. Perfect angle is 90 degree but its unrealistic as this will block the puddle viewing so suggest 15 degrees. Grinding tungsten: always use a dedicated grinder. Set the "Cleaning/Penetrating" setting to the more "Penetrating" side - around 7 on a scale from 1 to 10. Set the "Air on" to about 5 seconds, if you have the option to do so. This is the amount of time the gas stays on after the arc stops, to keep your weld from oxidizing/rusting. Set the "Max Amps" pretty high - perhaps around 250. CommonProblems: Balling end on tungsten rod: polarity reversed. Wrong gun angle Wrong gas Too much/ little Gas flow Too far from workpiece (cant weld without increasing amps)
