The D10T2 can deliver rated net power SAE J/ISO of kW hp in reverse With approximately 20% more power in reverse you can return faster for reduced cycle times increasing productivity and lowering the cost per unit of material moved Air to Air Aftercooling weld oscillation Adjustable bracketry as well as vertical and horizontal Micro Fine Adjustable Rack Boxes allow the welding gun and the oscillator head to be easily mounted adjusted and accurately positioned in virtually any plane off the front or back of the “KAT”® carriage INTENDED / FORESEEN USAGEConventional Positioner Model AH VP1 5 Page 7 South Service Rd Grimsby ON Red D Arc Welderentals L3M 4G1 Phone Efax Version Website v2 0 1 5 CE CERTIFICATE OF CONFORMITY Machine Type Welding Positioner Model AHVP1 5the ideal position for downhand welding But sometimes a posi tioner performs another important function it provides the weld travel speed by securing a welding head in a fixed position and allowing the positioner to move the part This eliminates the op erator variable and is another major step toward better welds Mar 19 Simple Relaxation Oscillator using a Single BJT The negative resistance area of a reverse biased silicon transistor can be applied in a relaxation oscillator circuit Its benefit is that an excess transistor is utilized instead of a UJT which is generally more expensive and it does deliver a minimum of components High precision state of the art controls on the KAT® carriage automatically direct the desired forward/reverse movement or dwell of the welding gun and its oscillation motion to produce the numerous weld patterns shown below The carriage control enables the carriage speed and direction to be pre set and shown on its LED display in IPM or cm/min Up to 10 weld programs can be produced and t or Curved Surface Weld Oscillation All Position WeldingThe KAT® Weld Oscillation Automation Carriage is comprised of the Compact Oscillator head controls mounting brackets connecting cable 1 1/8" heavy duty micro fine rack boxes with rack arms for horizontal and vertical adjustments Tuned Oscillators use a parallel LC resonant circuit LC tank to provide the oscillations There are two common types • Colpitts – The resonant circuit is an inductor and two capacitors •Hartley– The resonant circuit is a tapped inductor or two inductors and one capacitor •Oscillation welding uses a single mode high power laser with a scanner to rapidly move the laser beam in the weld pool •The weld depth and width can be controlled independently •Adjust scanner parameters to control weld shape •For best results oscillation frequency should be high •Oscillation welding is more tolerant to gaps and fit

In this type of crystal oscillator design the filter consists of the crystal’s equivalent model and the external load capacitors The exact frequency at which an oscillator will operate is dependent on the loop phase angle shifts within the oscillator circuit Changes in the phase angle will result in a change in the output frequency Applying Barkhausen principle of oscillator design this shall mean that overall loop gain A = j j ω ω ω RC 3 1RC R C − 2 2 2 AV = 1 From real part and imaginary part of the complex number solution the resonant frequency fr of the oscillator shall be fr = 2 RC 1 π 16 8 The voltage gain A V of the amplifier should be 3 This shall Develop a prototype mechanized gas metal arc welding machine complete with motorized carriage torch holders and related accessories to consistently and reliably weld butts and/or fillet welds on mild steel and aluminum sheets ranging from to and plates ranging from to APPROACHBy combining welding gun oscillation movement with the precision controlled travel speed of the Kat carriage up to 10 weld programs can be produced and stored Yes I am interested!Dec 31 Oscillation is not the same as " width of the weld bead" Oscillation is the amount of electrode movement Say for example the weld puddle width is 1/4 inch without oscillation and a 1/8 inch diameter electrode is used that is oscillated 2x the diameter 1/4 inch The final weld bead width would be about 1/2 inch from toe to toe Oscillation is the side to side manipulation of a weld in progress It is measured in amplitude how far frequency how often and dwell time for how long There are a number of ways and reasons a weld process would be oscillated Dec 06 The insertion and removal of the welding electrode are represented by short breaks in the flickering To cut off the welding light the circuit we must either remove the supply voltage or else ground pin 8 GP3 J1 provides an elegant approach to the latter solution The welding effect is active with the jumper removed Leading Wholesale Trader of Automated Oscillation Welding Carriage Welding Cutting Carriage Trackless Fillet Welding Carriage Automatic Fillet Welding Carriage Welding and Cutting auto Carriage and Fillet MIG Welding Carriage / Trolley from Vadodara Interested in this product Oscillation can be achieved by mechanically manipulating the welding head but oscillation of the arc alone is an attractive and cheaper alternative A simple electromagnet can be attached to the welding torch to produce a magnetic field in the welding direction which causes the arc to be deflected in the transverse direction
