ARGOTRON SERIES

Mould Welder ARGOTRON Series

ARGOTRON 350

Argotron series are the resistance-type micro welder which effectively build up the metal material to repair or redesign molds and dies.

The resistance welding method for Argotron series creates high energy discharges in very short cycles through a capacitance circuit. No heat is created and, therefore, the base mold material is not altered or damaged.

The Argotron Model 350 is a Push-Button type therefore it is easy to operate without the special training. The standard welding conditions are pre-set therefore it can be easily operated for anybody by selecting the push-button. It is not necessary to consider the detailed conditions in advance.

Applications

-Welding can be made to steel molds and dies for plastics, rubber, die casting, compression molds.

-Welds can be applied on as-rolled steel, pre hardened steel, quenched and tempered steel, free cutting steel, stainless steel and others.

-Building up of parting lines, mold seams, 3-point corners and edges.

-Filling in pores, repair of pinholes.

-Repairing wear, worn areas on slides, ejector pins, sharp edge molds, thin core parts.

-Modification of inserts and cores.

-Adding a radius to an inner corner due to a design change.

-Repairing the shrinkage that occurs after argon arc and TIG welding.

-Repairing damage due to over grinding, from an end mill or EDM / wire cutting.

Precision Mould Repairs made easy with ARGOTRON MOULD WELDER

  • Perform high-quality repairs to very small mould areas.
  • Increase the life of a mould after a repair.
  • Reduce repair costs by up to 85% with special metal alloys developed for all conventional types of steel.
  • Modern control electronics ensure homogeneous welding pattern even under the most difficult working conditions.

ADVANTAGES

  • The process emits almost no heat.
  • Mould repairs can be done without removing the die from the press thus saving time.
  • Hardening and plating can be done after welding.
  • Only gentle pressure is required on welding electrodes to produce zero pin hole or cavities.
  • Magnetic electrodes enable accurate placement of powdered metal on the repair position.
  • Suitable for all forms of mould damage. No need for other types of welding, e.g. argon, laser welding.
  • Safe and easy to operate, no special training necessary.
  • No harmful welding fumes or toxic gases are emitted.
  • The Argotron range of welding alloys are free of impurities which result in a weld which is strong and reliable.

THE MICRO-WELDING METHOD

Using only gentle pressure ARGOTRON uses electrical pulses to fuse metal plates, strips, powder or wire to the contour of the mould under repair (Fig. 1). A magnetic electrode for easy use of metal plates,, strips and powder,, containing alloying properties of the material being welded, are first fused then bonded to the base metal by a systematic and controlled supply of energy.
This produces a weld (Figs. 2 and 3) which also can be controlled by various adjustments of the power pack (frequency of the electrical pulses, output current).
Example of the weld by Precision Function is shown in Fig. 4 and 5.
Special training is not needed to carry out this welding process.
