Max 171 ATX

Brand Name: STEL

Model: Max 171-ATX

Origin: Italy


• The New Max 171 ATX is an Inverter Welding Power Source suitable for the welding of electrodes 1,6Ø - 3,25Ø. Owing to the insulation class IP54 this robust welding machine is designed to operate in extreme environments especially where severe dust and water prove hazardous.

• The Inverter dynamics of the Max 171 ATX also allows for the welding of demanding Electrode types’ including Cellulosic and Aluminium.

• V.R.D. means: VOLTAGE REDUCTION DEVICE which is the reduction of the OCV (open circuit voltage) at a safety level below 20V, in order to avoid Electrical Shoc.

Emergency Stop:
- With Power Input Cable 1 Phase 3 Core, the Emergency Stop disables only the Power Source;
- With Power Input Cable 1 Phase 4 Core, the Emergency Stop disables the Power Source and the Input Supply.
