Pneumatic Portable Resistance Welder Ac Manual Long Arm Hwashi

Hwashi Pneumatic AC Manul Spot Welder, Long Arm Welding Machine

This type of AC spot welder utilizes the general mains supply to lower the voltage and increase the electric current. Such kind of low voltage but large current will be transmitted from the electrode to the linked point of two work pieces. On the linkage, due to the resistance of work piece, high temperature will occur so the metal will therefore generates high heat to make the work pieces in molten condition. Thus, the purpose of welding the two work pieces is achieved.

The power of the pneumatic AC pulse spot welder that we produce is from 25KVA to 800KVA. It can be used to weld 10mm of iron and metals like stainless steel. Applicable to all kinds of hardware.

Features:

1. Rugged Welded Steel Frame.
2. Intellectual Microprocessor Control KD5 with Dual Current, Dual Weld Time, Upslope and Pulsation.
3. Digital Phase Shift Weld Current adjustment from 01% to 99% for Precision Welding.
4. Maintenance Free Solid State SCR Contactor.
5. Dual Voltage 220V-440V / Single Phase / 60 Hertz output Welding Transformer.
6. Soft Touch Control Pad with LED function and value indicators.
7. Adjustable Throat Depth on the Rocker Arm.
8. Speed Control adjustments.
9. Two Stage Electric Footswitch with the option to add a second Footswitch for Dual Current.
10. Combination Air Filter and Pressure Regulator with Gauge.

Applicable Area:

Wide appication. It can applied to iron wire products, hardware decorative lighting, kitchen utensils, small household appliances, small hardware, etc.

Feature
1. Three-phase power supply, grid balance, small impact on the grid
The power factor is as high as 0.7-0.9 (power frequency 0.4), which greatly reduces the reactive power loss.
2. Significantly improved welding control accuracy
The inverter frequency reaches above 1000Hz, and the welding current control ability and control accuracy are 20 times higher than those of AC welding machines.
3. Great leap in welding quality
The current waveform is straight, the size of the nugget is stable, the spatter is less, and the surface quality of the solder joint is good.
4. Save basic investment and save energy
The grid power demand is low, only 2/3 of the AC resistance welding machine; the welding time is short and the electrode life is long.
5. Human-computer interface, easy to operate
Multiple sets of welding specifications can be stored and called with one key, real-time display of welding current and time, monitoring and alarm functions of welding pressure, cold water flow, and welding current.
