Multimaster 260 Inductance Module
PN-0558001794, Color: Tan
PN - 0558002888, Color: Black
Installation Instructions
1. Remove four sheet metal screws from plate covering the Inductance mounting location on
the inside of the Multimaster 260 spool compartment.
2. Cut the plastic tie wraps holding the two Fast-On connectors and disconnect then remove
the Inductance position cover plate and discard.
3. Connect the Fast-On connectors of the Inductance module to the mating fast-on of the
Multimaster 260 wiring harness.
4. Carefully stuff the wire harness and connections through the access hole being careful
not to pinch any wires between the mounting plate and the compartment panel.
5. Reinstall the four sheet metal screws into the Inductance module plate and secure.
Inductance is used to optimize short circuiting arc performance by changing the current rise
and fall time of each short circuit. This results in improved spatter control, weld bead wetting
and arc stability. It is HIGHLY RECOMMENDED that the Inductance Trim option be used for
Optimum short arc welding performance for stainless steel wires.
The “easy to set” dial is calibrated in wire alloy (Carbon Steel and Stainless Steel) and
Shielding gas:
100% CO
2
Argon - 25% CO
2
Argon - 8 to 15% CO
2
TriMix (Stainless Helium, Argon and CO
2
Mixtures)
The short circuiting Mig arc performance will change from a “high short circuit frequency” fast
reacting arc to a “lower short circuit frequency” soft and less spattering short circuit arc as the
dial is turned clockwise. The optimized arc performance will vary depending on shielding gas,
wire diameter and alloy. Gases and alloys other than those indicated can also be optimized
with this control. Feel free to experiment. You cannot damage the Multimaster 260 by chang-
ing the position of this dial.
