A3 MIG Rail System 2500

Simple efficiency

A compact, battery-driven mechanization solution for MIG welding

Kemppi K3 Welding equipment Read more


A3 MIG Rail System 2500 is a simple and compact battery-driven solution for mechanized MIG welding and thermal cutting for applications where weaving is not needed. In mechanized welding, instead of welding by hand, the welding carriage carries the gun, making the arc movement steady. The handy system is an easy and cost effective choice for weld lengths exceeding 2 m as well as multi-layer welds. It is suitable for welding thick plates in medium-to-heavy industries, e.g. in shipbuilding, offshore, and general fabrication. The system can also be used for plasma or oxy-fuel cutting. The smart WiseFusion process provides significant additional improvements in welding production efficiency.

Benefits

  • Unique Kemppi application software significantly improves the production efficiency
  • Save setup time using a battery operated model
  • No cable costs
  • Lightweight carriage is easy to move around and lift on the rail
  • No connection to another power supply needed
  • Battery capacity for 8-hour operation
  • Battery is an industry standard version and commonly available
  • Easy-to-use. Simple operation with speed adjustment and change of direction.
  • Saves time in preparation and welding because the equipment is also suitable for thermal cutting.
  • Operates on the same flexible aluminum rails as A5 MIG Rail System 2500

NO COST OR FUSS FOR CABLES

A3 MIG Rail System is a battery-operated model, it does not need to be connected to other welding equipment or an external power supply. You save the cable investment cost and, without extra cables, taking the equipment where you need it is quicker and the working environment safer.

Weld 25% more per year

WiseFusion makes it possible to weld at a significantly higher speed, providing the same quality level and throat thickness as with a conventional spray and pulse arc. Synergic fusion is 20% faster than 1-MIG and pulsed fusion, and even 38% faster than conventional pulse welding. Welding speed increases from 60 cm/min to 72 cm/min, and arc-on time is 4% higher as there is no need for arc length adjustments (50-52% duty cycle). One of our use cases actually proved that you can weld 161 km (25%) more during the year with WiseFusion!
