with the 0.8 mm wire. However, also 0.6 mm or 1.0
mm wire diameters or tubular wires can be used.
NOTE: The apparatus is designed for the use of steel
wires only!
The welding power supply, wire dispenser and wire
feed mechanism are located in a single compact tin
box. The welding apparatus meets the relevant re-
quirements all standards and regulations of the
European Union and the Czech Republic.
NOTE: The apparatus is designed for the industrial
use.
Temperature-rise tests have been conducted at the
ambient temperature and loading factor of 40
°
C has
been determined by the calculation.
Safety standards
Welding machines must be used for welding and not
for other improper uses. Never use the welding
machines with its removed covers. By removing the
covers the cooling efficiency is reduced and the
machine can be damaged. In this case the supplier
does not take his responsibility for the damage in-
curred and for this reason you cannot stake a claim
for a guarantee repair. Their use is
permitted only by trained and experi-
enced persons. Comply with the safe-
ty instructions and warnings shown in
this User Guide!
COMPLY WITH THIS USER GUIDE!
Adequate safety devices and equipment protecting
against injury must be used during the welding oper-
ations.
Welding inverters must be solely for welding opera-
tions by the MIG method; they are not intended for
other nonconforming use.
The device may be used only under the operating
conditions and at place specified by the manufactur-
er. The welding apparatus must not be used in con-
fined spaces (such as in a crate, vessel, etc.). Do not
place the welding apparatus on wet surfaces! Always
check the condition of power supply and welding
cables before any welding operation; damaged or
unsuitable cables must be replaced immediately!
Welding operations with damaged cables may result
in serious injuries or damage to the welding appa-
ratus. The cables must not be in contact with sharp
edges or hot spots.
Insulate yourself from the welding current circuit by
the use of suitable protective clothing. Avoid any
welding operations while in wet clothing! Do not
place the welding torch or welding cables on the
welding apparatus or other electric equipment.
The welding power supply with the IP23S protection
class is not designed for outdoor use while raining,
unless they are placed under a shed.
DANGERS WHILE WELDING AND SAFETY INSTRUC-
TIONS FOR MACHINE OPERATORS ARE STATED:
EN 05 06 01/1993 Safety regulations for arc welding
of metals. EN 05 06 30/1993 Safety rules for welding
and plasma cutting.
The welding machine must be
checked through in regular inspections according to
EN 33 1500/1990. Instructions for this check-up, see
§ 3 Public notice ČÚPB number 48/1982 Digest.
