2. INTRODUCTION

2.1 GENERAL DESCRIPTION

WELDKAR MIG 2125
The Weldkar WK MIG 2125 is a powerful 230 volt MIG
inverter. This, the smallest member of the Weldkar MIG
family, stands out for weld quality, compactness and
simplicity.
With a weight of only 12.5 kg, this portable, robust
machine is the ideal welding tool in the workshop and
on site. With mains voltage of 230 volts and maximum
welding output of 200 amps, it offers a wide range of
applications on steel and CuSi3.
The machine is stepless adjustable, equipped with a
burnback control, "wave control" (maintains a steady,
smooth welding arc in the short arc area) and central
connector.
The strong cast aluminium 2-roll wire feed unit
transports the welding wire trouble-free over a maximum
length of 4 meters. The machine is provided with CE and
EMC and suitable for generator use.
The weld inverter is supplied as standard with a:
- WK MIG 2125 Inverter Power source
- Earth clamp with 4-meter earth cable and DIN Plug
- MIG Welding Torch WK 150 - 3 meter
- Power cable 5 meter, 3 x 2.5 mm²
- Gas hose
- 2-roller wire feed unit in aluminium
- Operating manual
The instructions below provide detailed information for
the correct and safe use of the machine and instructions
for obtaining the greatest efficiency and quality from
your power source.
IT MUST NOT BE USED TO DEFROST PIPES.

2.3 EXPLANATION OF THE TECHNICAL
SPECIFICATIONS LISTED ON THE
MACHINE PLATE.
This machine is manufactured according to the following
international standards: IEC 60974.1
N° Serial number. Must be indicated on any
request regarding the welding machine.
Single-phase static transformer-rectifier
frequency converter.
Suitable for MIG/MAG Welding.
Drooping characteristic.

I Max. absorbed current at the
1max
corresponding current l
I This is the maximum value of the actual
1eff
current absorbed, considering the duty
cycle.
IP23 Protection rating for the housing. Grade
3 as the second digit means that this
equipment may be stored, but it is
not suitable for use outdoors in the rain,
unless it is protected. Suitable for use in
high-risk environments.
H Isolation Class.
AF Aircooling with fan.

2.4 THERMAL PROTECTION

This inverter is protected by a thermostat. When the
thermostat is tripped, the machine stops delivering
current but the fan continues to run. The yellow led (9)
lights to indicate when it is tripped. Do not shut off the
welding machine until the led has gone off.

2.5 MOTOR-DRIVEN GENERATORS

These must have a power equal to or greater than 6
kVA, and must not deliver a voltage greater than 265 V.
