Max 503

Brand Name: STEL

Model: Max 503

Origin: Italy



Description:

Maximum Reliability

• The Inverter Welding Power Source MAX 503, has been designed for Electrode Welding, Mig and Mig Pulse Welding, Tig Lift. Its principal characteristics are: Robust, portable and reliability, welding of most electrode types including Aluminium, Cellulosic and Arc Force Adjustable, Remote Control, Tig Lift, Slope Down Adjustable, Hot Start Adjustable, VRD.

Slope Down variable (0-10 sec.), Smooth descent for a perfect Craterfill.
Arc Force variable (0-500%) a continuous arc for perfect fusion and penetration, no arc snuffing.
Hot Start variable (0-50%) for a precise arc ignition, eliminating electrode sticking.
Digital Amp/Volt Display
Tig Lift with ramp-down time (0-10sec.)
VRD Safety System
MMA electrode Pulsing (only with Remote Control RCCS)

• Rubust and reliable ideal for site work in the construction industries.
