- Ultra-fast, low-induction inverter
 - Robust 4-roller wire drive with tool-free changeover option
 - Stable chassis with large wheels; designed for 50 liter gas cylinders
 - Highest continuous duty: CRAFT-MIG.ARC 404 bis 504 provide more than the duty cycle required for continuous high level use
 - SDI® (Stepless Dynamic Induction) - stepless, electronic welding choke with ultra-fast control for excellent ignition characteristics and a stable arc
 - FOCUS.ARC: The welding process for more performance in conventional welding with CRAFT-MIG.ARC 404 bis 504
 - 7" large color display with Sirius user interface: Two different operating modes selectable, operation like stepless units (-> All welding parameters and settings at a glance) or operation like stepped units (-> Step adjustment from the torch) 
 - Angled torch connection guarantees ideal wire guidance and serves as protection for the cables
 - Suitable for crane or forklift transport
 - Well-protected control panel with 3mm thick protective screen and cover flap (cover flap only on models with wire feed case) 
 - Increased reach of the feed case by 1.5m due to front connections of the intermediate hose package
