The LAN 315 and 400 welding power sources fulfil the requirements of IEC 974-1.
INSTALLATION
The LAN 315/400 are delivered as standard connected for 400V/50 Hz, but if specially ordered, may also be connected for other mains voltages (230/415/500V 50 Hz, 230/440/550V 60 Hz).
- 1. Put the power source in a suitable place and make sure that the rectifier is not covered or positioned so that cooling is obstructed
- 2. Check that the rectifier is connected for the correct mains supply. Earth the equipment in accordance with the applicable standards. The earth must be
connected to the main earthing point marked 🕀 on the plate to the left of the mains terminal XT1. Refer to the wiring diagram page 66.
- 3. The mains cable supplied with the machine is dimensioned for mains voltages of 400V or higher. If the machine is connected to 230V or a longer mains cable is necessary then a heavier cable should be fitted.
- 4. Connect the control cable to the control socket XS1 marked 42V on the welding power source and to the wire feed unit.
- 5. Connect the welding cable from the wire feed unit to the socket XS2 marked (+) on the welding power source. Connect the return cable to the workpiece and to one of the sockets marked (-).
- 6. If a water cooling unit is used, connect this terminal XT3 (230V, 250VA). The earth lead must be connected to the main earthing point.
NOTE
There is a risk of tipping while transporting and storing if the welding equipment leans more than 10°. Note that the stabiliser must be fitted to increase the stability, (i.e. when Feed Selector, Puls-Aid or counter balance are used).
S
The symbol S in means that the power source is designed for use in areas with increased electrical danger.
IP
IP -The code describes the degree of protection provided by the casing, against the pentetration of fixed objects and water.
Equipment mark IP 21 is designed for indoor use, while IP 23 is also intended for outdoor use.
OPERATION
Mains switch QF1, Coarse setting switch SA1 and fine setting switch SA2.
Power is supplied to the control circuit when the mains switch is set to position 1, the fan starts and indicator lamp HL1 is lit.
Set the arc voltage using the coarse setting switch SA1 (four settings) and the fine setting switch (ten settings). There are a total of 40 voltage settings.
Main contactor KM1
When the trigger on the welding gun is depressed the main contactor closes and the main transformer TM1 is connected in.
Main transformer TM1
The main transformer is of the three phase type and can be reconnected for various mains voltages and frequencies.
Rectifier bridge V1-V6
The rectifier bridge is a three phase bridge using parallel connected diodes. The diodes are mounted on large heat sinks in the path of incoming cold air. To protect the diodes against transient voltage spikes a capacitor C2 is connected across the welding terminals with a load resistor R1 connected in parallel. This protection is supplemented by two suppressing capacitors C3 and C4 connected between + and earth, and between - and earth.
Ignition kit V7
The purpose of the ignition kit is to improve the starting characteristics of the power source by short-circuiting the inductor at the moment of starting. This has the effect of increasing the rate of rise of the short circuit current so that a stable arc is formed immediately.
Control transformer TC1
The control transformer is a single phase transformer with a 42V secondary voltage rating and a power rating of 310 VA during continuous operation.
The secondary winding supplies the control output XS1, which is fused with a 10A slow automatic fuse FU1. LAN 315/400 has a three pin terminal XT3 (230V, 250VA max) intended for connection of a water cooling unit. This terminal is protected by two 5A automatic fuses, FU2 and FU3.
Inductor L1
The purpose of the inductor is to limit the short-circuiting voltage and produce a "quieter" weld with a minimum of spatter. The inductor is connected in series with the welding circuit and is fitted with a resistor connected in parallel. Welding socket A is used for welding thin sheet and socket C is used for heavier material.
Thermal cut-out ST1
The welding rectifier is equipped with a thermal cut-out which protects the equipment from overheating due to heavy loading or insufficient cooling. The thermal cut-out cuts off the control circuit and the main contactor opens, disconnecting the main transformer. The thermal cut-out is located on the rectifier bridge and is reset automatically when the power source has cooled down.
Cooling fan M1
The power unit is cooled by a two speeds operation fan.
Thermostat ST2/ST3
The thermostats are placed on the rectifier bridge's heatsink (ST2) and the transformer's core (ST3), and controls the speed of the fan via a capacitor, C5, connected in series. Normally the fan runs at reduced power, but if the temperature rises above 60 °C thermostats ST2 and ST3 closes, supplying power to contactor KM2 which bypasses capacitor C5 and the fan speed increases to full. The thermostat automatically returns the fan to low speed once the power unit has cooled down enough.
MAINTENANCE
The LAN 315/400 require very little maintenance. In normal use all that is needed is to clean the inside of the power source twice a year using compressed air at a reduced pressure.
Measurement of open circuit voltage
The open circuit voltage should be measured during the annual service or as a part of troubleshooting. Measurement can be made using a universal meter or voltmeter.
- 1. Disconnect the welding cable (+) from the power source.
- 2. Connect the meter between the positive terminal and one of the negative return terminals. Make sure the meter is connected for the right polarity.
- 3. Loosen the wire feed pressure roller so that wire cannot be fed forwards when the trigger is pressed.
- 4. Start measurements with switches SA1 and SA2 set to 4/10 (coarse setting/fine setting). Work downwards to 1/1.
- 5. Compare the measured values with the static characteristic for the power source. The open circuit voltage = the voltage of the power source when unloaded, i.e. when wedling current = 0.
Measurement of arc voltage
Insert the meter probes between the rubber sheath and the cable on each of the welding cable terminals. Make sure that the probes make good contact with the brass part of the terminals. The arc voltage can now be measured during welding.
