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.
