The MTS 3500i is a high performance constant voltage (CV) and constant current (CC) inverter power source designed to provide multi process welding capabilities with dependability and ease of use. The MTS 3500i is a self-contained unit which will produce power for Gas Metal Arc (MIG), Gas Tungsten Arc (TIG) and Shielded Metal Arc (Stick) welding without the use of optional apparatus.
For MIG (CV) welding, the MTS 3500i supports welding a wide selection of ferrous and non-ferrous alloys by utilizing Fixed Slope and inductance controls.
A special "Touch Tig" circuit eliminates the need for high frequency or "scratch" starting when using the TIG (CC) welding process. This feature provides smooth starts without contaminating the electrode or the work.
The Stick (CC) welding mode provides adequate open circuit voltage (70 V dc) for easy starts and re-starts as well as an adjustable arc force which controls arc penetration and wetting action.
The "Auto Fan" feature operates the cooling fan only when the contactor is energized or when the internal temperature exceeds the safe operating level. During normal operation, the fan shuts down about 5 minutes after the contactor disengages.
