TUNGSTEN ELECTRODES FOR ARGON WELDING

AWS - ASTM
Item Description Color Current
Standard
The electrodes contain 99.50% tungsten. Intended primarily for EWP AC
aluminum and magnesium. DC current is not used because it does
not ignite a strong arc.
The electrodes contain 2% thorium and therefore the arc is very EWTh-2 DC
stable bow, designed mainly for use with DC currents. Be careful of
he radioactivity when grinding.
More durable than tungsten thorium and can be used with direct EWCe-2 DC וא AC/DC
current and alternating current. Excellent arc ignition, mainly with low
DC currents, and is therefore very popular for use in welding of pipes,
delicate parts and pulse welding. No radioactivity when grinding.

Excellent function in both AC and DC when used in reverse polarity (-), EWLa-1 DC וא AC/DC
heat resistance slightly better than gold.

Excellent function in both AC and DC when used in reverse polarity (-). EWLa-1.5 DC וא AC/DC

Excellent function in both AC and DC when used in reverse polarity EWLa-2 DC וא AC/DC
(-), heat resistance a slightly better than gold, and most similar in
properties to thorium, stable arc, option to work also with AC and
most importantly not radioactive.

Like the red-colored electrodes, with a reduced content of thorium EWTh-1 DC
- 1%, and thus a stable arc, intended primarily for DC currents. Care
must still be taken when grinding due to radioactivity.

More durable than tungsten thorium and can be used only with EWZr-1 AC
AC current. High resistance to contaminants. Little spatter. Not
radioactive when grinding.

Slightly better in heat, more durable than tungsten thorium and can EWZr-8 AC
only be used with AC current. High resistance to contaminants. Little
spatter. Not radioactive when grinding.
