VanderPro MMA 250amps DC Welding Machine Inverter Portable Mini Welding Heavy Duty

It is light, compact and excellent for industrial use. " has high efficiency and performance. heavy duty cycle 60%, easy arc ignition, excellent formation of welding seam. small volume. and simple operation. it apply to welding low carbon steel. low alloy steel and so on.2. Model Unit MMA series welding machine adopt advanced inverter technology. I is light, compact and excellent for industrial use. " has high efficiency and performance. heavy duty cycle 60% easy arc ignition, excellent formation of welding seam. small volume. and simple operation.it apply to welding low carbon steel. low alloy steel and so on.MAX NO-LOAD VOLTAGE CURRENT RANGE DUTY CYCLE INSULATION GRADMODEL:MMA-250RATED INPUT VOLTAGE220 ± 10%FREQUENCY50/60 HzPHASE:SingleINPUT POWER:7 KVA-60V/20 - 250A3.Voltage characteristic and current characteristic of welding power sourceThe curve (as diagram 1-1) means"V.A" external static characteristic of welding power, gradient of cure named slope, normal means "drop off voltage per IOOA". The curve shows the output voltage we can get in any preset output current because the "V-A" slope is fixed. PRODUCT DESCRIPTION1.4 Equipment conditiona.Surrounding temperature rangeDuring welding: - IOC +40CDuring transit and storage:- 25 0 C - +550 Copposite humidity when 40 0 C when 20 0 CDust acid active gas or object in surrounding air can't exceed normal content, except these objects that be brought by welding course.Altitude height must 100mGradient of welding powerNoise AnnounceWhen the machine is working. it maybe has noise, but the noise can't exceed 75 decibel.6.SafetyBefore operating the equipment. you must read the safety directions to avoid the hurt that because of misapply and impropriety Installing.AccessoriesHammer/brushThe hammer brush will make the operation more confidentlyMask (with welding screening black glass) When welding. the mask will protect your eyes and face.Electrode holder (with 2M welding cable)Earth clamp (with 2M earth cable)If the equipment can't work normally, you should stop working at once and check trouble reason. You must use career man to maintenance; forbid somebody that without training to check clear or repair equipment, when repairing, you'd better to use commendatory spare parts.Before any maintenance, make sure the main switch has been cut.CleanlinessTake the shell and sideboard trimly and use cleanly and dry low-pressure air to blow dust and dirt on air alleyway and inner parts. Clear the dirt. dregs and begrime on the head of welding tongs trimly. Make sure the clean frequency according to the circumstance.In order to enough circulating and supply proper cooling, it s necessary to keep the alleyway cleanliness.After cleaning by low-pressure. check if any hardware has been fixed. If fixed, you must firm them include all electric contactor. Check if insulation of cable has been frayed. if the cable has been frayed, you must replace it.Before any maintenance, make sure the main switch has been cut.Place the cable in clean and dry place.
