5. GENERAL DESCRIPTION
SPARTUS® ProMIG 420H / ProMIG 420HW
Professional, industrial MIG welder
(TOWER type)
with separate wire feeder. Made in inverter tech-
nology using the highest quality components. It enables welding MIG/MAG and MMA. Max wel-
ding current is 420A for both methods. Device is powered from three phase 400V source power.
Control panel allows smooth adjustment of parameters: welding voltage, wire feed speed,
inductance control
(MIG/MAG mode)
; welding current
(MMA mode)
. Source has built-in digital
displays of welding parameters.
High-class 4-roll wire feeder allows you to work with long MIG gun. Using separate wire feeder
further enhances range of device. Wire feeder is equipped with handy grip and wheels.
Robust design allows installation of a large cylinder with shielding gas. So composed set can
be moved easily due to durable wheels.
SPARTUS® ProMIG series H and HW
. This solution dedicated to specialized industrial applica-
tions. Machines are ready to work in toughest conditions.
5.1 PURPOSE OF USE
SPARTUS® ProMIG 420H i 420HW welding devices are designed for:
• Manual Metal Arc (MMA) welding,
• Metal Inert Gas (MIG) / Metal Active Gas (MAG) welding (MIG/MAG),

Duty cycle
(def.)
Duty cycle is the time during which You can weld or cut at a certain load without causing overload.
It is expressed in percent for period of complete cycle which equals 10 minutes. For example: 60% duty
cycle means that for 6 minutes device can operate at given load, after that required 4 minutes time
break (no-load operation). Duty cycle is given to ambient temperature of 40°C.
