Power source designed for carbon arc gouging
A lightweight, heavy duty air carbon arc gouging power source's characteristics curve has been designed specifically for the process, so optimising gouging properties and minimising noise.
Welding equipment manufacturer, Kemppi (UK), based in Bedford, whose parent company is Kemppi OY in Lahti, Finland, has launched KempGouge ARC 800.
It is a lightweight, mobile, heavy duty air carbon arc gouging power source The 400V three-phase 50/60Hz machine has a rated input power of 44kVA at 50% duty cycle and a rated load capacity of 800A/44V at 50% duty cycle at 40 deg C, when using a gouging carbon up to maximum 13mm diameter.
The current adjustment range is 20 - 800A and the recommended compressed air pressure is 500 - 700kPa (5 - 7bar).
* Easy process control and monitoring - the control panel allows the user to easily control and monitor the equipment, with the current and voltage values being clearly shown.
The required gouging current is set in adjustments of 10A.
This KempGouge ARC 800 is designed for all types of carbon arc gouging found in many fabrication and production industries.
It can be used on most metals, such as steel, stainless steel, cast iron, nickel, copper, magnesium and aluminium.
It can be used for numerous applications besides back gouging, using either a round or flat gouging carbon.
Examples include the following.
* Removing welding defects.
* Preparing grooves.
* Cutting metals.
* Making holes.
* Performing arc grinding of surface defects and weld caps.
* Opening casting defects.
The characteristics curve controlling the equipments operating parameters has been designed specifically for carbon arc gouging, so its gouging properties are optimised, while operating noise levels are kept to a minimum.
The equipment weighs just 115kg with its portable trolley and measures 700mm long x 660mmm wide x 1400mm high.
