Hold Pressure - This pressure determines the amount
of force applied during Hold.
Typical weld setups have Hold Pressure higher than
programmed Weld Pressure.
Increasing hold force (pressure) during Hold helps to
produce stronger weld bonds.
For a basic weld setup, program Hold Pressure at 10 psi
above Weld Pressure. See Figure 4-34.
Upstroke Pressure - This pressure is applied at the
end of the Hold time. This is the air pressure that drives
the air cylinder to move the system back to its home posi-
tion.
Upstroke pressure has little or no effect on weld results.
However, overall cycle time is affected by upstroke travel
time.
For a basic weld setup, program Upstroke Pressure at
80 psi. See Figure 4-34.
