3 INTRODUCTION
3.1 General
By way of the conversion kit an A2 SFE welding head or an A2 TFE tractor can be
converted from SAW to MIG/MAG welding.
All parts necessary for the conversion of the welding head are included in the kit.
Before using the system for M IG/MAG welding, cooling water and shielding gas must
be connected to the welding head, and some adjustments m ust be made in the con-
trol system as well.
Instructions regarding these adjustments can be found in the instruction manual for
theA2--A6ProcessController.
