UWI-400 welding inverterUWI-400 welding inverterProduct Group: 191Product number: 670398General descriptionA welding machine for electrode, TIG and MIG/MAG welding.FeaturesMulti-function welding machine for stick electrode, TIG and wire weldingCan be connected to any 3 phase primary voltage between 380 V and 440 V, frequency 50-60 HzAutomatic shut down function against input voltage, fluctuations outside 10% of rated voltage rangeDisplay information to operator on display stating reason for shut downStepless current control from 5-400 AHot start, arc force control and anti-stick functionsParallel connection for extra power (2xUWI-400)Fan on “demand” tunnel coolingRemote on/off and remote amperage controlConforms to code of safe working practices for merchant seamenBenefitsMulti-functionalSafe in useEfficientTechnical dataWelding current range5-400Open circuit voltage63 VDuty cycle at max current30 %Electric phase3Power supply voltage380-440 VPower supply cycles50/60 HzRecommended fuses (slow)20 ACertification (approval)CEIP protection23Weight34.5 kgLength492 mmWidth320 mmHeight400 mmDesigned for marine applicationsA process selector switch provides quick and easy selection of optimal welding characteristics for all processes required for on board maintenance; electrode, TIG (with Lift Arc), wire welding and air carbon arc gouging.5-400A current range covers the use of any size of welding electrodes.Low weight and compact dimensions provide easy transport to wherever welding is needed.Designed for marine conditionsAutomatic shut down protecting against input voltage fluctuations or attempted overload. Display information to the operator stating reason for shut down. Specially designed tunnel cooling and high grade aluminium casing for optimal protection against salty corrosive atmosphere, dust and other atmospheric contamination. Fan on demand function can be used as needed; onboard repair welding is normally done at low duty cycle, continuous cooling will therefore mean excessive power consumption and cooling tunnel contamination.Specifications in full conformity with code of safe working practices for merchant seamen to ensure operator safety.Optimal arc control and operator safetyWith the remote control the welder has full control of the welding circuit and may switch off welding current/secondary voltage completely both when changing electrodes and in case welding cables should be damaged or short circuited. The remote control enables the welder to place the electrode in the groove, close the face shield, then switch on power and start the arc exactly where the weld shall begin. The power may be adjusted continuously during welding.Plugs in anywhereWithout any reconnection the UWI-400 may be connected to any 3 phase primary voltage between 380 V and 440 V, frequency 50-60Hz. At voltages outside this range the machine will close
