Operatingmanual of hydro pneumatic press automate forwelding:

1. To start machine by two hand buttons,time relay controlsmachine''s return stroke.
2. Connected to power, in the "manual" state,operator can makemachine do low force inching rise or inching drop action bypressing inching rise or inching drop buttons,so as to correctmoulds.
3. In the "automatic" state, machine will start after operator putworkpiece on work bed and press switches by two hands.during fastapproach stroke, the upper moulds move to workpiece quickly andgently with low-noise, no impact, when upper moulds contact withworkpiece machine will build up full power(power stroke)automatically from fast low force approach stroke until set-up timeover,then time relay controls moulds returning automatically,so asto insure machine builds up enough pressing force required.
4. Speed of Fast approach stroke and returning stroke can beadjusted stepless, so as to meet different working frequencyrequirement.
5. Machine''s maintenance system can process inlet compressed airso as to make it gas-water seperated and oil atomization, you canalso adjust the pressure of inlet air source stepless, so thatmachine''s output force is adjustable stepless.
6. With an emergency returning button, moulds can returnimmediately anytime.
7. There is a power stroke regulating valve, which can adjustpressing force of power stroke while machine''s speed is notchanged, in this way it can protect moulds and energy-saving.

 Attentions of hydro pneumatic pressautomate for welding:

1. Adopt easy and safe return circuit design,meet safetyrequirements of press machines, if you need further securityprotection facilities, please contact us.
2. Each machine''s output force is theoretical value, practicaloutput force is 85% of heoretical value,when you use our machinesplease ensure supply stable air source.
3. Please take machine''s open height into account,pleasecalculate the height of your moulds and workpiece.
4. Hydro pneumatic press has oil tank,please fill oil between topand bottom oil line,please use ISO VG 68 anti-wear hydraulic oil.hydraulic oil should be changed every year or 500000 cycles later,if oil is emulsified please change oil.
5. Please attention air source treatment''s drainage function, ifit is ineffective, please change new one.
6. When machine does not work for long time please releasemachine''s pressure.
