OPERATING MANUAL
3.3.9 Autoprogram
Autoprogram for 300-series weld heads always uses
position-based programming. Each pass is divided into
six levels. Certain defaults are automatically selected
(for example, Prepurge is always 5 seconds). To change
these defaults, edit the weld program after it has been
generated.
The Autoprogram feature only creates a maximum of 5
passes (rotations around the pipe), which should allow
weld thicknesses up to 12.7 mm (0.5") to be programmed.
For heavier walls, create a new weld program and slightly
increase Pass 5 oscillation parameters for each subsequent
pass.
If password protection has been applied, you will be asked
for your password to continue. Select New Weld Number
using the control knob. Press Next when nished. Use Back
to move to prior screen.
To create a new program using Autoprogram:
1. Select Yes. (If password protection has been
applied, you will be asked for your password to
continue.)
2. Select weld number.
3. Feed the parameters of the welding task: head,
OD, wall thickness, material, bevel type, number of
passes, program mode, and guide ring factor.
Once you enter the OD, wall thickness, and material, the
system automatically chooses the correct guide ring
factor (GRF) based on the OD. If the OD is not a standard
tube or pipe size, e.g. 2.333” instead of 3.375, the system
will default to 8.0 for the GRF.
If your OD is not standard or you are using an oversized
guide ring (with guide ring insertion kit), you must change
the GRF to obtain correct travel speed. You should always
check that GFR in the program matches with the GFR of
your guide ring.
Next Weld to Run (two choices)
1. Repeat the weld program. At the completion of a
weld, the same program is automatically loaded,
eliminating the need to enter the Weld Number
again.
2. Run a dierent weld program to create readymade
work cycles. Press Next when nished.
You can chain several programs, or if you use the same
welds repeatedly, return automatically to the beginning of
the program.
