Welding Equipment selection criteria

  • Welding process type
  • Welding Characteristics
  • Duty cycle
  • Environment – Ambient Temperature
  • Degree of protection class for enclosures
  • Supply – Standard through Busbars or through DG sets
  • Special applications like pipe laying etc
  • Welding current stability or dynamic response

Welding process type

  • SMAW
  • GMAW
  • GTAW
  • SAW

Special considerations

  • Printed circuit boards should be coated with protective layer to protect them against the conducting and non-conducting dust- These PCBs should not be in the main air ventilation path
  • These PCBs also should preferably be housed in the metallic or plastic box
