Dc spot welding machine for welding radiators
Hs code:8514400090
Introduction
This device is the new idea of portable induction heating method, in the old times, if you need to heat a metal part, you have to use nothing but fire (oxygen-acetylene). It somehow has the potential danger for the man who use it.
Thanks to the electro-magnetic induction, now we can use only electricity, with a voltage lower than 36v on the coil, it will be safer than any other means heating. Fast and clean, easy to adjust to any position.
This device generally used in
1. In the garage repairing center: rusted bolt are not easy to remove from the old component, with durowelder-1kw, you can heat it to nearly 800 celsius without fire, much easier to remove rusted bolt, stuck bolt, rusted nuts on vent pipe caused by sault road.
2. Remove bumper sticker by a flat coil, easy to heat car body surface above 60 centigrade to remove stickers.

Automatic rolling seam welding for radiator sealing.
DFI Series Digital Force Gauge is our latest microprocessor digital indicator gauge. It has inputs both for dynamometers (force) and load cells (weight) strain gauges.
It is ideal to be used in the most innovative static and dynamic measurement systems such as material testing machines, printing machines, test benches and automation.
Thanks to its ??0,02% accuracy DFI can be used in quality systems as first or second line sample item if regularly calibrated by SIT centre.
The measurement system is made up of an analog section particularly stable at long term, of a carryng frequency feeder which lowers the system thermal drifts and of a 16 bit A/D converter which guarantees 65.000 internal divisions.
In order to increase the integration level of the components a traditional mixed tecnology and SMT has been adopted to make the indicator resistant to any kind of vibration and mechanical stresses besides granting the highest reliability of the circuit.
The internal batteries guarantee 1 year autonomy also thanks to the AUTO POWER OFF function which activates when any measurement change is detected within 30 minutes.
The indicator is equipped with a setting menu which allows to choose the most suitable type of engineering measurement units (kN, daN, lbs, t, kg), the resolution and the digital filter according to the measurement to be calculated.
The display also shows a bar analog indication which is operating inside the setting menu too.
When the instrument is working in compression mode, SP1 icon is alight; when it is working in tension mode, SP2 icon is alight.

Introduction
Resistive spot welding (RSW) is a process in which contacting metal surfaces are joined by the heat obtained from resistance to electric current.
Work-pieces are held together under pressure exerted by electrodes. Typically the sheets are in the 0.5 to 3 mm (0.020 to 0.118 in) thickness range. The process uses two shaped copper alloy electrodes to concentrate welding current into a small "spot" and to simultaneously clamp the sheets together. Forcing a large current through the spot will melt the metal and form the weld. The attractive feature of spot welding is that a lot of energy can be delivered to the spot in a very short time (approximately 10–100 milliseconds). That permits the welding to occur without excessive heating of the remainder of the sheet.
Applications:
1. Mild steel sheet, stainless steel sheet, galvanized metal sheet spot welding.
2. Metal sheet fixing welding before continues rolling seam welding.
3. Welding fan guard (with proper designed fixing and driving system), welding metal art ware, stationery, cook ware.
4. With special made electrode, it can weld small mesh, birds cage, pets cage, condenser and similar work piece.
5. Weld connection parts, the hinge, nuts and bolt welding, low carbon fasteners and stainless fasteners.
6. Welding high conductive material, like aluminum, electrical contact, copper wire etc.(using Middle frequency power)
Single plate thickness:
1. Uncoated mild steel sheet: 0.4-4.0mm
2. Stainless steel sheet : 0.5-4.0mm
3. Galvanized steel sheet (hot dip zinc, zinc5% aluminum, zinc55% aluminum and electrolytic ally deposited zinc coated steel sheets): 0.4-2.5mm

? Automatic argon arc(plasma) straight seam welding machine mainly includes two parts: specially designed straight seam automatic machinery part and standard welding source part
? According to different welding requirement of various materials, the automatic straight seam machinery part can be designed into two kinds: plate type pressing mechanism and keyboard type copper pressing mechanism, to get the regular and stable clamping and cooling effect.
? Standard welding source part includes tig(tungsten inert gas shielded arc welding), mig(metal inert gas shielded arc welding) mag(metal active gas arc welding) saw(submerged arc welding)paw(plasma arc welding), etc, automatic machinery part can be equipped by the standard welding source manufactured by our company , can also work with other well-known brands of welding power
? Automatic machinery part is adopted plc control, dc motor drive has variable welding speed and interfaces with any power source.
? Weld seam back up design has a groove to form a weld on the bottom of a welded plate and provide consistent gas flow to the back of the weld, to assure the stable gas shield and ensure double-side forming in single side welding.
? Automatic straight seam welding machine is mainly used for the high quality and low distortion automatic straight welding, such as metallic cylinders and aligned plates made with stainless steel, iron, aluminium and brass, etc.
? Compared with the traditional manual welding way , high welding efficiency and speed, well welding quality and good consistency
