Character of resistance spot welder/spot welding

(single) double AC pulse energy storage welding/resistance spot welder, which is reliable for welding result

CPU control, high definition LED display 240*64, the operation is visual and be more precision

128 user-defined welding procedures, all of them can be locked by manager

State locking technology, which can avoid false triggering

The unit can integrated into automatic production line

Can set pedal switch to detect the welding parts before power generating

Can set prepressing time before power discharge

Radio (RFI) and electromagnetic interference (EMI) protection

Power box and welding section are separated, which is safer

Pneumatic and pedal control in one machine, which is more flexible

Discharge time can be set between pulse 1 and pules 2

long, medium and short-pulse adjustable to fit fine welding

Mainly parameter of Resistance spot welder/Spot welding

Rated power: 3.0 up 500watts/second (joule), the display screen can show the whole (maximum) energy percentage (%), the tolerance is 0.5%, the display screen is 0.1% up 0.5% in required energy

Stability of power box: changes in the nominal voltage supply of +/- 13%, the power box can keep the voltage of capacity band at set value of +/-0.25%

Display screen: the display screen adopts 240*64 high definition LCD, is visible for debugging

Capacitor control circuit: when the voltage of error amplifier is over the required value to cut off charging circuit, one resistor connects at two sides of capacitor bank, by which let the voltage of capacitor bank work at required level, the dead zone of capacitor control circuit is about 0.6% of maximum voltage

Line fault step-down: the is for safety purpose, when the power supply cut off suddenly, one resistor of voltage step-down automatic connects to release the power of capacitor bank

Ignition circuit: Ignition requires an external account is closed or low-touch control logic circuit, inside filtering device can prevent electrical interference (RFI) triggered over ignition

Power supply: 220v, AC, 50/60HZ, 2635watts rechargeable, 35wattes as spare, When 230V, 2A Cutout

Welding ignition lock: error amplifier output, when charging and discharging to prevent ignition circuit, which is helpful to prevent to ignition before capacitor charging and discharging, the welding ignition lock circuit can prevent defected welding effect

Programmable Prepressing time: combine with ignition welding head in the manual and automatic working mode without welding pressure, guarantee electrode is positioned well with welding parts before welding energy outputting, the prepressing time can be programmable (range:0.1 up 9.9 seconds) remote program selection: four monopole input: remote selection#1-#128 procedure; remote to prevent capacitor bank charging, when do remote program, the operation panel can be instead

Valve drive output: can control electromagnetic valve of pneumatic welding head, 24VAC, 15A output

Output pulse characteristic: at the side of power output, multiple a non-inductive load of 0.01 ohms, at both ends of it to measure pulse characteristics, to measure the rising time between zero amplitude and maximum point, to measure the pulse width at 10% amplitude point
