Wire Feeders for Submerged Arc Welding

NA–3, NA–5 — these systems are specially designed to deposit more weld metal at faster travel speeds.

They are used for heavy–duty fabrication and assembly line production for welding with solid and flux–cored wire.

• Solid state controls give precise control of welding procedures, striking characteristics, start and stop bead size and shape,
  and arc stability.
• The unit's solid state controls and rugged construction minimize downtime and maintenance costs.
• The unit is easily adjusted for a wide range of processes, feed speeds and wire sizes.
• The unit's remote control system can be used for integration
  into automated systems.

NA–4 — this unit is intended to operate with the AC–1200 power source.

Otherwise it is analogous to the NA–3 and NA–5 systems described above.
