Projection welders

Features

• Plenty of capacity variatons
• Adopted pressurization system combining cam follower type roller guide rams and follower springs
• High frame rigidity ensures high accuracy even with large electrode force
• The lower platen height can be adjusted in three steps (50mm pitch) to match the dimensions and shapes of the workpiece and jig.
• Greatly improved working environment because oil-impregnated air is not released into the atmosphere
• Improved operability with an operation box that integrates individual switches
• Respond according to customer specifications

Features

• Plenty of capacity variatons
• Direct setting of welding current and time, which was not possible with conventional capacitor welding, is possible.
• The input is as low as that of an arc welding machine, and the size of the capacitor box is 1/3 that of the conventional type, which saves space.
• Adopted pressurization system combining cam follower type roller guide rams and follower springs
• High frame rigidity ensures high accuracy even with large electrode force
• Welding current is stable at constant current control
• The energization time is controlled in ms (1/1000 sec) units, and current waveforms such as DC/AC, two-stage energization, and pattern energization are freely available.
• Clean welding finish without thermal deformation by energization of extremely short time and large current
• Equipped with forge force function, energization starts direct reading of electrode force with the load cell.
• Electrode force can be measured by the load cell and digitally displayed.
• We will respond according to the customer's specifications.

Features

• To be welded from mild steel to special steel, S45C, etc.
• Applicable to transmission parts, air bag parts, pulleys, steering, hermetics for compressors, etc.
• Capacitor system makes power source facility very small
• Since the arrival time to the peak current is as short as 10ms, welding with less discoloration due to thermal distortion or heat is possible.
• Energy,electrode pressure, welding current,upsetting, and other characteristics are monitored to determine their upper and lower limits, which ensures quality.
• These welders can weld parts of sintered metal and parts of different kinds of metal together, such as iron with brss.
• Your old equipment for lelctron beam, laser beam, and arc-welding　can be replaced with there machines to cut costs in parts and shorten cycle time.
• Welding with less distortion and discoloration is possible because the current discharged from the capacitor is passed through the transformer to the workpiece in a short time
• In the case of a portal frame, the transformer is placed on both sides to balance the current and to cancel the electromagnetic force.
• Steel and brass edge-ring projection welding available
• The mechanism of upper electrode parallelism adjsuster available.

Features

• There projection welders are suited for applications that requires large currentsn and high precision.
• A larger current can be flowed than single phase AC. Three-phase balanced load reduces the load on power source. The flicker phenomenon can be greatly reduces.
• Since there is almost no reactance drop on the secondary side, high output and uniform welding with little scattering are possible.
• Pressurized cylinders are diaphragm-type depending on the model, making them extremely responsive.
