Ventilation
During welding, there is presence of a heavy current; therefore, the natural draught cannot provide
sufficient cooling. Ensure good ventilation via the ventilation slots of the machine. The minimum distance
between the machine and all other objects within or near the working zone should be 30
cm. Good
ventilation is vital for the normal performance and service life of the machine.
Welding
This welding machine is equipped with an overcurrent protection, overvoltage protection, and overheat-
ing protection. If the input voltage or output current is too high or the inner temperature of the machine
gets too hot, the machine switches itself off automatically. When used too much (e.g., use with too high
a tension), the machine might be damaged; take account of it.
Welding is forbidden with the machine being overcharged. Bear in mind to always respect the maximum
load current (see corresponding duty cycle). Make sure that the welding current does not exceed the
maximum load current. If the machine is overcharged, its service life can be reduced or it might even be
damaged.
Overvoltage is forbidden. The tension range for the power supply of the machine is given in the “Welding
parameters” chart (see below). The machine is equipped with an automatic tension compensation that
keeps the tension range within the rated range. Should the input tension exceed the given value, the
components of the machines might be damaged.
Sudden standstill might happen if the machine is in a protection cycle. In this case, restarting the ma-
chine is not necessary. Let the integrated fan running and lowering the inner temperature of the machine.
Description
The working principle of this welding machine is to rectify the input AC current into DC current, and use
high-power IGBTs to convert the DC current into high-frequency AC current, then reduce and rectify the
voltage.
The welding machine is equipped with a synergic adjustment function. The user does not need to adjust
the working voltage and feed speed separately; thus, it will be easier to operate the machine and to
achieve a good welding effect.
Other advantages of the welding machine:
•
reliable and stable IGBT inverter technology
•
tolerance with unstable working voltage
•
electric throttle control, simple arc ignition, less spatters, stable current, good shaping
•
easy-to-use synergic adjustment
•
compared to usual welding machines, highly reduced number of electric components and im-
proved switching reliability
•
efficiency factor of this welding machine can reach more than 85
%
Note!
•
This welding machine has no gas function (fluxing agent); therefore, it can only weld a max. of
1
kg welding wire. When using, choose the appropriate size of welding wire.
•
Also, note that the size of nozzles and wire spool should be equal. — Example: With a 1.0
mm
wire, use the 1.0
mm electrode in the welding gun and the 1.0
mm side of the wire-feed roll.
