ESAB KHM 190 HS, Instruction Manual

Page: 22 / 98

The KHM 190 HS is an engine driven welder and is both:
a) a current source for arc welding b) a generator of electrical current
The machine, which is powered by an internal combustion engine, is meant for industrial and professional use.
The engine is directly coupled to a three/single phase alternator. The complete assembly is mounted inside a
protective frame with lifting point using antivibration mounts.
DC welding current/voltage at duty cycle 190A/20V at 35%

The output indicated is guaranteed at 20°C and at a pressure of 1 bar (up to 1000 m no correction for atmosphere
pressure is required). At high temperature and above 1000 m altitude the engine output will decrease and the engine
may need adjustment for optional performances.
+ 1%
at high altitudes, the standard mix air-fuel is excessively rich, the efficiency of the engine is reduced and,
therefore, the fuel consumption will increase.

Max. acoustic power level admitted according to the EEC norms of 17/09/84 n. 84/535-536.
The machine respects the noise limits, expressed in sound power, given in the a.m. directives.
These limits can be used to judge the sound level produced on site.
For example: the sound power level of 100 LWA.
The sound pressure (noise produced) at 7 meters distance is about 75dBA (the limit value less 25).
To calculate the sound level at other distances use this formula:
dBAx = dBAy + 10 log At 4 meters the noise level becomes: 75 dBA + 10 log = 80 dBA
