REMOVING WAYS
3. The LED monitor shows nor

mal, the fan is working, run the
machine, the red lamp is on.
1. Over current protection.
1. Stop working for five minutes.
2. Over temperature protection.
3. lt may be wrong with inverter
circuit and leading arc board.
a. The red lamp is on, the
wrong is in the inverter.
(if double inverters, after clos

ing the machine, pull off the
socket. (nearby the fan VH-
07) Run the machine and
press hand-switch, the red
isn’t on, be sure this inverter is
wrong. The red lamp is on, be
sure that inverter is wrong.
2. Close five minutes and re

start the machine .
b. Close the machine and put
on the connections of the bad
inverter. pull off the connec

Run the machine and press

on, individual MOSFET is dam

aged. Meanwhile check the
components on drive module.
c. If the main transformer are
damaged, we can measure
them by electricity bridge, the
value is too small, replace it.
3. Check and measure the
rectifications tubes one by
one and replace the same
type components.
d. Check and Removing the
rectification tubes one by one
4.Run the machine, press the
hand-switch the red lamp is
on.
The feedback circuit is open

4. The welding splash is very
much.
It is wrong that output elec

trode connections. You may
exchange output lines.

5. The welding current isn’t
stability.
1. The variable resistance is
damaged.
1. Replace.
2. Put current remote control
on remote position.
2. Put on “off” position.
3. The output cables are too
long or slim .
3. Thicken the cable.
4. The filter capacitance leaks
electricity or damaged.
4. Check and replace.
