The T-Frame Welder is a full function (travel, AHC, oscillation and wire) weld system designed to make FCAW and GMAW fillet welds joining the T-frame to the base plate.
Weld power is provided by the Lincoln Electric PowerWave S500, which is controlled by the T-Frame Welder’s process control system.
To facilitate rapid assembly, disassembly and ease of transport, the T-Frame Welder is made up of a number of lightweight modules:
- Universal weld carriage
- Oscillator assembly
- Height control assembly
- Wire feeder.
The operator’s pendant is used to set and adjust the weld and sequence parameters. This pendant can be kept in a mounted position on the carriage, or detached for handheld operation when desired. The pendant and the network of controller components in the Jiffy Welder’s distributed control system makes up the process control system
The semi-automatic MIG and FCAW weld control system is modular in design to optimize weld process control while minimizing operator training. The system provides control of the weld carriage travel and all weld sequence parameters, which are easily set and adjustable from the operator’s pendant.
Weld process control is incorporated via several modules integrated into the weld system. A microprocessor, distributed I/O and master logic PCB are located within the carriage guard while the motion control system is directly integrated into the motor of each axis.
All motorized axes utilize DC high torque stepper motors with integrated motion controllers and micro-stepping drives. Due to the use of these stepper motors and precision circuit design, the T-Frame Welder’s process control system requires no field calibration. The motor only needs to be programmed for the appropriate axis for repair and replacement to be complete.

- Travel Axis – This axis is used to move the weld carriage along the track, parallel to the joint to be welded.
- Cross Seam – This axis moves the torch assembly across, which is perpendicular to, the weld joint. The cross seam axis is used by the operator to steer the torch while welding ensuring that the torch tracks the weld joint in the event that there should be any discrepancy between the joint and the path of the travel axis.
- Torch Height Control – This axis controls the distance between the weld torch tip and the weld surface.
- Oscillation – This axis positions the torch assembly across, which is perpendicular to, the weld joint. The oscillation axis is used to weave the torch back and forth during the weld process.
- Wire Feeder – The wire feeder delivers wire to the weld torch at the desired rate when welding.
