FONMATIC ALLOYS AND EQUIPMENT

INTRODUCTION  Flux-cored arc welding (FCAW) with shielding gas is certainly not new to industry. With Fonmatic self shielding flux-cored wires and Fonmatic semiautomatic welding wire feeders, you can now lead in production with higher deposition rates and better economy.
THE CONCEPT In self shielded flux-cored arc welding, continuous tubular wire filled with flux is used in a spool form. The wire is fed continuously into the arc by means of a special wire feeder. The arc is struck by touching the wire to the job. The heat of the arc melts the wire and forms a weld puddle. The flux core essentially has the same functions as the external coating on a stick electrode. The other alloying elements added in the flux, provide desired mechanical properties to the weld metal. To obtain sufficient protective shielding gases, normally a longer stickout (electrode extension approx. 30 to 40 mm) is required in self-shielded flux-cored arc welding.  The self - shielded flux-cored arc welding process is popularly used for fabrication, reclamation welding, hardfacing and surfacing applications.
FONMATIC WIRE FEEDER  : WF - 90 Salient Features:   Suitable for AC or DC Constant Potential or Drooping Characteristic welding power source (Min. OCV for AC power source should be 80 volts) Sturdy and reliable 4 grooved gear roll drive system to get smooth wire feeding without slippage Portable, light weight and compact Very easy and fast installation. No auxiliary voltage required  Facility for wire inching by a separate push button Fine tuning regulator knob for the most optimum parameter setting Will also work with 'constant potential' power sources as used with MIG welding sets
THE KROSS - 500  The KROSS - 500 open arc welding outfit is fully equipped to tackle your problems in reclamation welding. The power source is a three-phase air cooled, transformer-rectifier unit with 'constant current' or 'drooping' type output characteristics. It is an ideal DC power source for SMAW, GTAW or other welding processes which need such dynamic characteristics. The use of KROSS - 500 can lead to a significant increase in productivity.
