Main supply

The power source (only HandyArc 132i DV) will automatically adjust to the supplied input voltage

which is 127/220V AC, whereas HandyArc142i and162i are 220V AC. Make sure that it is protected

by the correct fuse rating. A protective ground connection must be installed correctly, in accordance

with regulations.

Parts Functions

START PROTECTION CONTROL To avoid equipment breakdown, the power source measures the

mains voltage when the power switch is turned ON. To protect

the power source, check that the mains voltage is correct

according to the rating (120/230 V AC) before switching on the

power source.

RECTIFY AND FILTER Transfer the power from AC into DC.

INVERTER Increases the frequency (43 kHz) and transfers the power from

DC into AC.

DECREASE VOLTAGE Changes the high voltage into lower to get high energy.

SECOND TIME RECTIFY Transfer the power from AC into DC.

CONTROL CIRCUIT Estimates the PWM signal and controls the entire process.

DRIVING CIRCUIT Controls the switch for inverter circuit.

AUXILIARY POWER SUPPLY Supply power for CONTROL CIRCUIT and DRIVING CIRCUIT.

FEEDBACK CIRCUIT Gets sampling from the output, sends feedback to CONTROL

CIRCUIT.

Duty cycle

According to the IEC 60974-1 standard, the duty cycle is the relationship between the welding period

(Open Arc) in a period of 10 minutes. To explain, the time period used by the IEC standard (10

minutes) is used in the following example. Suppose a welding source is designed to operate at a duty

cycle of 15% to 90 amps. This means that the equipment was built to supply the welding current (90A)

for 1.5 minutes, that is, the arc welding time, every 10 minutes (15% of 10 minutes is 1.5 minutes) .

During the other 8.5 minutes of the 10-minute period, the welding source must remain on and cool.

Enclosure class

The IP code indicates the enclosure class, i.e. the degree of protection against penetration by solid

objects or water.

Equipment marked IP21S is intended for indoor use.

Application class

The symbol indicates that the power source is designed for use in areas with increased electrical

hazard.

6 TROUBLESHOOTING

6.1 Fault tracing

Pre power up checks

WARNING!

Make sure the power source is disconnected from the mains supply and wait at least 5

minutes for the DC bus capacitor to discharge before removing the power source cover!

Then remove the power source cover and measure the voltage between the "+" and "-"

DC-Bus capacitors soldering pads, using a multimeter. If the voltage between the "+" and

"-" DC-Bus capacitors soldering pads, is not < 20 V, wait further until the voltage is below

20 V!

6.2 Visual inspection

Examine the power source for any visible signs of damage. Especially check:

1. Printed circuit boards for burned varistors or other components

2. Cables and connectors

6.3 Components testing

Primary diode bridge

Use a multimeter set to diode test setting.

Connect the negative probe to DC+ and positive probe to DC-, it should read 0.85 ±0.2 V. Keep the

negative probe at the DC+ and connect the positive probe to each of the AC pins, it should read

0.47V±0.05 V.

Connect positive probe to DC -, and negative probe to each of the AC pins, it should read

0.47V±0.05 V.
