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 features
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.
SETUP & OPERATION:
(Refer to the Controls Sections pg. 6, 7 and Major Components section pg. 10, 11 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 left hand side of the control box to the “ON” position. Turn
“ ON” power to both feeders by toggling the feeder “ON/OFF” switches located on the front lower left
and right 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 or no 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
bottom center 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. The
Corner Followers are also equipped with a gun angle adjustment knob to achieve the desired torch
angle. 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. Each wire feeder’s wire speed and voltage are set independently from
each other utilizing the controls to the left and right of the soft touch Programming Center located
on the control panel. 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 press the Weld
Cycle Stop button.
NOTE: In case of an 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.
