SECTION 3 INSTALLATION

Selecting the proper Inductance for a specific application and shield gas is

mostly a matter of personal preference. The Inductance setting will change the

crispness of the welding arc and change bead shape by affecting the weld pool

fluidity. Table 3.2 is a general guide to setting Inductance level.

Table 3.2 Recommended Output Inductance Tap Connections for Short-Arc Welding

Notes: The above chart shows the recommended output inductance tap connection for Mig Short Circuiting Transfer.

For Mig Spray Arc Transfer (stainless or carbon steel) - use low tap

For Flux Cored Wire (all types) - use low tap

NR - Not Recommended

* The best connection (high tap or low tap) depends on the specific welding application and personal preference.
