- Page 4 We shouldlike to highlight the following features, which makethe Automig T welding machine a consider9ble improvement over any previous machines. Good strike: Before striking an arc, the thyristors are set in such a way that the initial voltage is higher than normal - as a result of which the arc strikes more easily when the wire touches the workpiece.
- Page 5 Minimum spatter: The Automig T's power source and regulating system are designed to produce a minimum of welding spatter. That cuts out any unnecessary grinding work and means the welding torch needs less frequent cleaning. Power Take-Off (PTO) for electrical...
- Page 6 spatter. When the switch on the torch is depressed, the thyristors come on. The rectifier emits a DC voltage - which is determined by the remote control in the welding trigger and the gas/wire matching switch (pos. 5) on the box. Simultaneously, shielding gas is turned on and the wire-feed motor started up at a speed also determined by remote regulation from the torch.
- Page 7 INITIAL OPERATION Mains connection: Check that the machine voltage on the type-plate conforms with the mains voltage on the site. If the machine is dual voltage or more, be sure to check that the machine is correctly set. The mono machine is designed for connection to single-phase 220-240 V (Ph. + Zero + Earth)/ 25 amps.

The thermostatically-controlled fan continues to run until thc machine has cooled down to normal operating temperature again, at which point the red lamp goes off and the machine is once again ready for use.
- Page 15 Seam: The machine welds when the torch switch is actuated and stops when the switch is released. Spot: When the torch switch is actuated the machine welds automatically, controlled by the "welding-time timer" (pos. 6). The time is adjustable from 0.2 to 2.5 secs, and when the set time runs out, welding stops.

- Page 23 TROUBLE SHOOTING If the machine fails to weld correctly, there are, in principle, two possible sources of error, namely wire feeding and power source. In the vast majority of cases, the error is to be found in irregular wire feeding. Try, where possible, pushing and pulling the welding wire out at the contact nozzle.
