WTC provides two types of steppers: both are used to assure
consistent heat to each weld (despite mushrooming and alloying
of the electrode tips). The method used to compensate for lost
current density varies:
• The LINEAR stepper keeps track of the weld count,
and gradually increases the heat after a programmed
number of welds. Heat is added in several “steps”
until the programmed set-point where the electrodes
must be filed or replaced and the stepper reset. (See
page 2-8.)
• The SUREWELD stepper monitors the power factor
during each cycle of a weld and calculates the point
where expulsion is expected to occur. The SureWeld
stepper uses this calculation to continually supply
weld current at a level just below the point of
expulsion. (See page 2-10.)
Note:
Not every weld control supports the SureWeld stepper. The
display does not show the SureWeld stepper options when
the weld control software does not support these features.
Some weld controls provide multiple independent steppers. Each
weld schedule can be assigned to a stepper, and you can define a
different profile for each stepper. (The profile tells the control
when and how compensation is provided.)
You program the stepper settings for each weld control using the
Review Stepper function (
) on the Program Mode display, to:
• Review a linear stepper profile
• Review the current limits for the linear stepper
• Review the SureWeld stepper parameter settings
• Assign a stepper to a weld schedule
