Plasweld 7000 Plasma Transferred Arc (PTA)


 Plasweld 7000 Automatic

For more than 20 years, Dura-Metal have been working successfully in the field of Plasma Transferred Arc ( PTA ) welding – particularly in that of Plasma Hardfacing.

We are pleased to introduce latest state-of-the-art PLASWELD 7000 Plasma Transferred Arc (PTA) system. It is a high quality, modular, robust system with hand-held deposition capability. It is engineered for accuracy and simplicity of operation. The PLASWELD 7000 system uses argon gas to deliver a controlled amount of powdered metal into an argon-7% hydrogen gas shielded plasma transferred plasma column so as to produce metallurgical bonded, wear –resistant coatings to the work pierce. Accurate control of the process parameters are possible including powder feed rate, current input, gas flow rates, as well as , upslope and down slope and arc voltage are integrated onto a PLC Controller of simplicity and accuracy. When hook up with suitable work handling equipment – the system will produce precise deposit profiles with minimal base metal dilution. The resulting coatings are assured to provide homogenous, optimal wear and corrosion resistance overlays. All these benefits are incorporated into a modular and robust system designed to be flexible and user friendly.  Simply one of the best PTA system that the market can offer.


  • Robust 350 Amp power supply and allows for any input voltage hook up ( 208V - 575V )
  • Consistent easy arc start and soft arc transfer to substrate
  • Unique power source designed protects internal electrical components from airborne contaminates. Also cooling system operates only when needed, reducing noise, energy use and the amount of contaminates pulled through the machine, thus extending product life
  • Extremely stable welding current and minimum heat effected zone during welding
  • Fully automated function allows for single button to turn system On and Off without any sequence being followed.
  • Ability to store up to 50 weld programs including voltage, amperage, powder feed rate, oscillation. All may be adjusted from a remote pendant.
  • Build in torch oscillation unit
  • Build in arc voltage controller ( AVC ) - automatically reduce or increase the arc length due to surface irregularities
  • Automated or semi-automated machine-mount installation or as a standalone hand-held installation. It can be easily integrated to a wok handling or robotic system.
  • Error prevention by constant monitoring and measuring of coolant and gas flow
  • Shortcut to needed parameters may be reach with one click or change with remote pendant
  • Smallest ID torch in the world ( Dia < 1.5” )
  • Handheld torch capability
