Product Name: Finger Protected Spot Welding Machine Model NO.: MDDL-6000C/T & MDHP-32 Type: Special Welding Spot Number: Single Conductive Way: One-Sided Transmission: Pneumatic Electric Current: Line Frequency Electrode Stroke: Vertical Style: Portable Cooling Way: Air Cooling Control: Manual Trademark: minderhightech Transport Package: Plywood Specification: 50kg Origin: Guangzhou HS Code: 8515290000 Product Description Finger protected Spot Welding machinePrinciple:A inverter resistance spot welding machine including(configuration) : 1: Inverter spot welding power supply2: Precision welding head3: Finger protect system(soft touch system, optional)4: welder checker(optional)5: Welding cable6: Electrode7: Jigs if needed.Good news! we developed the "soft touch system" to protect finger from pinch point injury when operate sopt welder. as below photo.1: Inverter spot welding power supplyCharacter:1,IGBT inverter with 4kHz frequency.2,Three welding pulses with upslope and downslope.3,Constant-current/constant-voltage/constant power/fixed pulse width control mode.4,Upper and lower monitor of the current or the voltage etc.5,Easily operating,.6,Full I/O interface. The power supply can be easily used on aautomatic machine.7,Over heat false/wrong input voltage false/over control false.Principle:As the main circuit diagram below, the inverter welding power supply working principle is :(220V 50Hz AC)-----(310V 50Hz DC)-----(310V 4kHz AC)-----(5-18V 4kHz DC). That is why the frequency being changed, because of the high frequency, the welder become more precision.1, for 50Hz, we can only set 20ms welding time as aunit. but for 4kHz, we can set 0.25ms welding time as aunit, 80 times inproved.2,when we do closed-loop constant control, the feedback speed is different, 20ms once by 0.25ms once, it is very much different.AS the waveform of pulse DC current is flat, not like AC curve and around "zero"We have compared that the DC power supply can sace more than 50% power than AC ones.2,Advantages of inverter seam welding power supply and the current waveform of capacitor type/AC type/inverter type/crystal typea,Inverter type of seam sealing power supply can saving 50% power than others.b,Inverter type of seam sealing power supply can improve 3% stability than others.means less defective products.c,Inverter type of seam sealing power supply can be much faster than others.SpecificationModel/NoMDD-1000MDD-2000MDD-3000MDDL-4000MDDL-6000C/TMDDL-10000C/TMDDL-20000C/TMDDL-40000C/TInput Voltage(V)220V220V220V3*380V3*380V3*380V3*380V3*380VRated Power(kVA)46101216254065Max current(DCA)10002000300040006000100002000040000Max time setting(ms)12501250125012505000500050005000Rated duty cycle(%)2020201010101010Frequency(kHz)44441111Welding step33333333Upslope downslopeYesYesYseYesYesYesYesYesSchedule memory2020202020202020Dimension(mm)435*185*320435*185*320435*185*320460*400*300460*222*345385*200*300510*270*400440*240*350Weight(Kg)1820.5223323.526354626.5304051Including 2: spot welding head1,Simple description: Electrode pressure -also known as 'force' -is akey parameter in resistance welding. Proper force guarantees both weld quality and consistency by improving fit-up of the parts being welded, thus increasing the current path and reducing interface resistance. Force is provided by the weld head.We offers afull range of resistance welding heads including manual, air-actuated, and electromagnetic models with opposed, step, series, and parallel gap electrode configurations. Force ranges from just 10N to 2000N (725.7kg) to address both fine and large scale spot welding applications.2, Technical parameters of some weld heads:ModelForce(N)Stroke(mm)Electrode holderElectrode typeapplicationMDHP-1020-10020Copper rodRod elctrodeWeldingMDHP-2020-10025Copper rodRod elctrodeWeldingMDHP-3230-20020Copper rodRod elctrodeWeldingMDHDP-2020-10020Copper blockRod elctrodeWeldingMDHP-6550-40045Copper rodRod elctrodeWeldingMDHP-200200-200045Copper rodRod elctrodeWeldingMDHP-20UB0-10025UB-WD1UnibondBondingMDHP-20UT0-10025UT-WD1UnitipWeldingMDHP-20RF0-10025RF-JY1thermodeReflow3,The high and low force spot welding heads:A, Fast follow-upB, Precision bearings ensure long lifetimeC, Displacement and load cell optionsD, Both benchtop and pedestal modelsE, Adjustable Force-FiringF, Low Inertia DesignsG, Air Actuated OptionH, Adjustable Tare SpringI, Single Air RegulatorJ, Up and Down StopsK, Rugged DesignPart of welding sample:welder type view:Factory view:-----------------------------------------------------------------------------------------------------------MINDER-HIGHTECHguangzhou minder-hightech co.,ltdcontact:shunyu.hu cellphone:0086-15813334038
