KHM 405 YS / YSX
KHM 405 YS / YSX
Digitally controlled engine driven welding units made to weld MMA, TIG or
MIG/MAG. For professional heavy duty repair, maintenance and assembly work
For professional work
The wide working range makes it possible to perform a
large variety of work in environments where it is difficult,
costly or impossible to connect to the mains supply. This
chopper controlled compact and transportable unit gives
you a combination of strong, high quality DC current for
excellent MMA, TIG or MIG/MAG welding. The same
unit also supplies up to 12kVA electric power while
CC - MMA and TIG welding
With a welding current of up to 400 A this machine welds
electrodes up to 6 mm. Using the Arc force control you
can fine tune the characteristics of the machine and
weld difficult electrodes, such as cellulosic, with
excellent result. The low 10 A minimum current allows
welding with very small electrodes and a wide range of
TIG welding applications with scratch start.
CV - MIG/MAG welding
After fitting a connector kit the unit can be used with the
wire feeders Origo™ Feed 304, M13 or Origo™ Feed
484, M13 for MIG/MAG welding.
Power generation – electric output
Electricity is often needed to carry out the complete job.
Drilling, grinding, drying electrodes and lighting are a few
examples. KHM 405 YS /YSX have a built in brushless,
maintenance free, asynchronous generator that supplies
up to 7 kVA single phase 230 V or 12 kVA three phase
400 V even when welding. A voltmeter shows the actual
supply voltage. The units are equipped with earth fault
protection for added safety.
The units are delivered as stationary. For transport
within the worksite there is an optional site tow. KHM
405 YS /YSX have a central lifting eyelet for safe lifting.
Service support
Careful consideration was taken when choosing engine
supplier. Since the engine is a large part of this unit,
good service and spares backup is an important factor. If
something should happen to the rest - ESAB has the
best service network in the welding business.
• General fabrication and civil construction
• Repair and maintenance
• Power generation

Diesel water cooled engine
KHM 405 YS /YSX are equipped with a powerful and
efficient water cooled Yanmar Diesel engine with battery
and electric start. The engine fulfils the EPA-EURO2
exhaust gas emission requirements. Engine protection
shuts down the engine if the oil pressure is too low,
temperature is too high, fuel level is low or if the battery
charging does not work.
Other features
• Noise level below the limits of the 2000/14-CE standard
• Hour meter for correct servicing.
• Lockable covers over the engine and control panel.
• Machines with Auto idle, polarity change and spark
arrestor are available.
• Sealed base prevents spilling of liquids on the ground.
• Welds up to 6 mm coated electrodes and 1,6 mm
MIG/MAG wire
• VRD (Voltage Reduction Device)
• Supplies 230V and 400V electric power for tools,
lighting etc.
• Reliable and economical Yanmar engines
