PULSE WELDING PROCEDURE
GUIDELINES
Tables B.2 and B.3 list initial settings guidelines for
pulse welding with the MIG PULSER for Stainless
Steel and Mild Steel. These settings are intended as
suggestions only. The serviceability of a product or
structure utilizing this type of information is and must
be the sole responsibility of the builder/user. Many
variables beyond the control of The Lincoln Electric
Company affect the results obtained in applying this
type of information. These variables include, but are
not limited to, welding procedure, plate chemistry and
temperature, weldment design, fabrication methods
and service requirements.
These settings were developed for joints in the flat or
horizontal position. Out-of-position work will require
adjustments to these procedures.
To tighten or stiffen the arc, try decreasing the Peak
setting. To widen or soften the arc, try increasing the
Peak setting.
