RESISTANCE WELDING & SOLDERING MACHINES
Series 2000 - 1 to 20 KVA
In the 1-20 KVA range, Hanson offers a fully integrated benchtop welding and soldering machine system. That is our model AP-2W resistance welding and soldering machine. It is offered with a wide range of options that permits the customer to virtually custom design each machine to meet his particular requirements.
Features/Benefits
Series 2000 Control
Microprocessor-based controller stores programmable, preselected weld schedules. Schedules are programmed and recalled through a hand-held pendent that prevents unauthorized changes.
Unique approaches to voltage compensation and phase shift heat control eliminate variables that cause inconsistent welding performance. No other controller can match the degree of precision and consistency provided by the Series 2000.
Head Assembly Designed for Durability and Consistent
Performance.
Low-inertia linear precision cross roller slide head assembly assures continued smooth operation and repeatable performance. Rugged construction for long, trouble-free service.
Head Force System Guarantees Precision Weld Performance.
The head force system is in direct alignment with electrodes. This enables follow-up response not available in cantilever-type
heads and assures precision weld performance.
Special Head Firing Switch Insures Repeatability and
Reliability of Welds.
A reliable feature on all Hanson welders. It allows the welding control to be fired only when the predetermined force range has
been reached by measuring the displacement of the head force system.
Transformer Design Minimize Possibility of Saturation.
Multi-tapped stacked core, epoxy-impregnated design, using high-grade silicon steel.
Built-In Versatility to Handle a Variety of Jobs.
Force system, stroke, electrode opening and squeeze and hold times are all fully adjustable to accommodate a wide variety of
parts sizes, materials and fixturing.
Modular Construction Permits Equipment Modification in the Field.
If requirements change, a welder can be modified by changing
transformer and/or force control springs and indicators.
Convenient No Heat/No Weld Switches for Safer, Easier Set-Up.
Minimizes chance of operator injury, set-up times are reduced.
Applications
The basic versatility of the AP-2W welder and the many options and accessories available make it suitable for welding a wide range of small to medium-sized pads. These machines are widely used in electrical/electronics, automotive, appliance, aerospace, jewelry and metal-working industries in metaljoining applications where precision is essential.

Welding and Soldering Controls
Series 2000 Microprocessor-based, Programmable Weld
Controller:
- Stores pre-selected weld schedules. Automatically controls Percent Heat, Squeeze Time, Weld Time, Hold Time.
- Heat Time Range: 1/2 cycle to 100 cycles
- Schedules are programmed and recalled through a hand-held programming terminal that prevents unauthorized weld schedule changes.
- Automatic line voltage compensation every 1/2 cycle of weld, starting with first 1/2 cycle.
- Unique phase shift control provides true under-the-curve adjustment for consistent welds.
- Battery back-up to protect memory
- RS232 port provides input/output interface
- Polarity selection switch and half-cycle control.
- Manual and automatic mode selector. Used to establish set-up parameters. Allows single stepping each sequence function when in manual mode.
- Heat/no heat selector switch. Used for set-up and dry cycling.
- Back-to-back SCR firing circuits.
- Head Firing Switch. Allows welding control to be fired only when the predetermined force range has been sensed through the displacement of the head force system.
- Two-Stage Foot Switch Initiation. In manual or semi-automatic mode.
- Up slope/down slope option. For applications requiring gentle heat-up prior to full weld energy or controlled cool down.
- Preheat/post-heat (quench and temper) option. Selectable in straight line steps. Preheat useful for brazing flux activation; post heat as an annealing function.
- Electronic cycle counter.
Options
- Weld Monitor
Weld monitors have been available for many years. Unfortunately, most of these devices are either current, or milli-volt second monitors, neither of which satisfy the basic requirement. To properly evaluate a weld, we must establish a correlation with what is happening electronically, and the mechanical test results. To do this we must have weld monitoring instrumentation capable of providing the necessary information. To properly monitor a weld, the equipment must measure current and area under the curve on each half cycle in A.C. applications, and measure current and area under the curve for each weld in D.C. applications. Further, it must be capable of calculating the product of these and reporting in half cycle increments, for A.C. applications. This product is called the weld energy, which is expressed in wattseconds or joules.
Finally, the weld monitor must be capable of accepting both upper and lower control limits with alarms to alert, or shut down the process.
Only Hanson Welding Machines, Inc. offers such a device. The optional weld monitor is an integral part of the Series 2000 Weld Control, and measures energy in real time, unlike remote add on monitors. It is fully programmable for upper and lower process control limits. The weld monitor audits every half cycle of weld, capturing the readings for current(in amperes) and milli-volt seconds (area under the curve). The product of these is expressed in joules of energy for each half cycle. The weld monitor protects against process shifts caused by dirty or worn electrodes, dirty or inconsistent product, equipment malfunctions, and countless other variables. The weld monitor stores the readings in memory for downloading to SPC packages for process capability analysis, or to printers for charting and evaluation.
