A2 Multitrac A2TG + GMH
The ESAB modular concept makes it easy.
A2TG Multitrac is designed to put your MIG/SAW operation on the right track to increase both the productivity and quality. Combining GMH joint tracking controller and PEK controller makes it easy for any welder.
A2 Multitrac
The A2 Multitrac is a self-propelled four wheel driven automatic welding machine. The compact and efficient design makes it easy to move and to set up the A2 Multitrac on different welding workpieces. The mechanical components are very reliable even under extreme working conditions. Feedback systems on the wire feed and travel unit ensures good weld results.
The advanced design makes it possible to adjust the nozzle into numerous positions to best suit the application. The heavy dimensioned feed unit with encoder feedback secures an even and stable wire feed and a must for high quality welding. Another feature which ensures constant welding speed is the four wheel drive carriage which also has an encoder for feedback and easy to change processes.
The A2 Multitrac + GMH can be delivered in two versions, MIG and SAW.
Accessories
To increase the profitability further there are a number of accessories available: standard and application specific guide rollers, guide wheel boogie for V-joint tracking, V-guide wheels, high temperature steel wheels, pilot lamp with a laser diode, twin wire SAW conversion kit and MTW600 MIG head conversion kit.
Cored wire – a high speed welding process
The A2 Multitrac can be used with cored wire. Productivity, economy and welding speed can be increased. When using cored wire in heavier sections the risk of lack of fusion is significantly reduced compared to welding with solid wire. Obviously the latter method is better when welding thin sections.
Programmed precision with Process Controller – PEK
PEK Controller is used with CAN BUS controlled ESAB
power sources. The controller is equipped with a large digital display which makes fast programming and control of all welding parameters possible.
255 different weld sets can be stored in the controller. Adjustments to current, voltage and travel speed can be made during welding. A USB port for storing or recovering all files, all settings and configurations.
GMH
The GMH system minimises repair welding and adjustments post welding. The arc is always in the optimal position via a sensor and two motor slides. The GMH system can track edges, fillets both left and right hand, V groove, height control only and many more.
The quality will increase and the operator is free to supervise the whole process not just the wire position during welding. A simple pendant is supplied for the operator to select what is needed then drive to the joint to be tracked then the system takes over automatically.
