INTRODUCTION:
The Programmable Stiffener Welder mechanizes two wire feeders to weld various types of stiffeners on
one or both sides simultaneously. The unit features independent wire feeder controls for voltage, wire
feed speed, cold wire jog and gas purge. When intermittent stitch welding is required the unit feature
programmable control of weld length and travel speed, skip length, reverse drive crater fill, pre-weld
and post-weld gas purge times. Please see the Technical Data information in this manual for unit
capacities.
SET-UP & OPERATION:
(Refer to the Controls Sections pg. 6, 7 and Major Components section pg. 9, 10 in this manual.)
1.
Center the unit over the work piece. Connect welding cables and wire feeder control cables for each
feeder to the welding power sources. Connect the welding gas hoses to each
Flow Meter/Valve
Assembly
. Plug the unit into an available 110 VAC 50/60 Hz power source.
2.
Turn power
“ON”
to both welding power sources. Turn power “
ON
” to the control panel by toggling
the “
ON/OFF
” switch on the upper rear right hand side of the control box to the “
ON
” position. Ensure
both welding torches are active by toggling the
Weld Contactor Switches
located on each side of
the control box to the “
ON
” position.
NOTE:
Ensure that the
Emergency Stop
Switch located on the top of the control box is in the released
position. If the
Emergency Stop
Switch remains depressed, no input power will be supplied to the unit.
3.
Adjust the
Capture Wheel Assemblies
so that they contact the side of the work. Swing the
Drive
Unit
into position against the work piece and engage the
Drive Latch
and tighten to ensure constant
pressure on the work piece between the Drive Assembly, Work Piece and Capture Wheel Assemblies.
NOTE:
Move the unit forward and reverse using the
Travel Manual Jog
switch located on the front
lower left of the control box to ensure proper tension has been applied by the
Drive Latch
to move the
unit smoothly along the work piece.
4.
Align the left and right
Corner Followers
and welding guns for the desired weld placement. The
Corner Followers
can be adjusted up, down, in and out to achieve the placement you desire. Coarse
torch angle adjustment should be made with the positioning of the corner followers. The
Corner Followers
are also equipped with a gun angle adjustment knob to achieve the desired torch
angle and correct position of the welding wire with respect to the joint. Purge the shield gas to each
welding gun by pressing the
Shield Gas Purge
button located on the left and right sides of
the control panel for each
Flow Meter/Valve Assembly.
5.
Set all welding parameters. Wire feeder wire speed and voltage are set independently from each
other utilizing the Lincoln LN-10 Controller. All other welding parameters are set using the soft touch
Programming Center
. Please refer to the controls section of the manual.
6.
When you are ready to begin your weld cycle press the
Weld Cycle Start
button located on the
control panel below the soft touch
Programming Center
. To stop the weld cycle pres the
Weld
Cycle Stop
button.
NOTE:
In case of emergency, press the
Emergency Stop
switch located on the top of the control box
to kill all power to the unit including the weld cycle. Once the
Emergency Stop
switch is returned to the
released position you will need to press the
Cycle Start
button to resume your cycle.
