Pulser
0-20 Pulses per second (default = off)
• Alternating peak and background current controls heat input.
• Minimize material distortion
TIP: Lower pulse frequency provides a reference for adding filler metal,
making you a better TIG welder faster.
(pulsing: 0.5 - 2.0 pulses per second)

A lower AC Balance (%EN)
results in an arc with increased
cleaning action.
A lower AC frequency results in
a wider bead.
A higher AC Balance (%EN)
results in an arc with
higher penetration.
A higher AC frequency results in
a more focused bead.

E6011 Deeper penetrating electrode that can be used in all positions. Frequently used for joining pipe.
E6013 Shallower penetrating electrode that can be used in all positions. Commonly used for wide root openings,
or conditions of poor fit up.
E7018 Low hydrogen electrode used for joints involving high-strength (structural), high carbon,
or low alloy steels. Smooth arc with medium arc penetration. Can be used in all positions.
