Starparts Purple E3 Tungsten Electrodes

Purple E3 Tungsten Electrodes ANSI/AWS A5 12-92 - BS EN 150 6848:2015 For many years 2% Thoriated Tungsten (Red tip coloured electrodes) was the preferred choice for DC electrode negative welding. Thorium is slightly radioactive and contains very small trace levels of naturally occurring isotopes that emit alpha particles at a very long half-life. Due to the increased awareness and trends to eliminate all radioactive sources (even at safe levels) from the work environment, some welding communities prefer using non-radioactive alternatives. E3 electrodes are also claimed to run much cooler providing faster and reliable arc starting and an extended tip life.

Starparts Black 1% Lanthanated Tungsten Electrodes

1% Lanthanated Tungsten Electrodes Black Tipped - Pack of 10 These TIG electrodes are alloyed with non radioactive lanthanum oxide, often referred to as lanthana, another of the rare earth elements. These electrodes have excellent arc starting, low erosion rate, arc stability and excellent re-ignition characteristics.  The addition of 1 – 2% lanthana increases the maximum current carrying capacity by approximately 50% for a given size electrode using alternating current compared to pure tungsten. The higher the percentage of lanthana, the more expensive the electrode. Since lanthana electrodes can operate at slightly different arc voltages than thoriated or ceriated tungsten electrodes these slight changes may require welding parameters and procedures to be adjusted. The 1.5% content appears to most closely match the conductivity properties of 2% thoriated tungsten. Compared to cerium and thorium the lanthana electrodes had less tip wear at given current levels. Lanthanum electrodes generally have longer life and provide greater resistance to tungsten contamination of the weld. The lanthana is dispersed evenly throughout the entire length of the electrode and it maintains a sharpened point well, which is an advantage for welding steel and stainless steel on DC or the AC from Advanced Squarewave power sources. Thus the lanthana electrodes work well on AC or DC electrode negative with a pointed end or they can be balled for use with AC sine wave power sources.

Starparts White 0.8% Zirconiated Tugsten Electrodes

White 0.8% Zirconiated TIG Tungsten Electrodes (Non-Radioactive) White Tipped Perfect for use on aluminium alloys & magnesium alloys in AC Current Balls well, handles higher amperage than pure tungsten with less splitting This TIG tungsten is alloyed with zirconium oxide (zirconia) and is preferred for AC TIG welding when the highest quality work is necessary and where even the smallest amounts of weld pool contamination cannot be tolerated. This is accomplished because the zirconium alloyed tungsten produces an extremely stable arc which resists tungsten spitting in the arc. The current carrying capability is equal to or slightly greater than an equal sized cerium, lanthana or thorium alloyed electrode. Zirconium electrodes are typically used only for AC welding with a balled end. The tungsten electrodes come in a variety of diameters and you would select the appropriate diameter for the current to be used and type for the process mode. To physically identify the tungsten type the end is dipped with a colour.    Take care to grind the non coloured end for welding. Pack Of 10
