4. MAIN - Op. (operating modes)
The welding power source provides the following operating modes:
• 2-cycle
• 4-cycle
• Super 4-cycle
• Spot welding/Interval
• External
4.1 2-cycle
Operating mode 2-cycle is provided for short manual welds.
1st cycle --> Press torch trigger
• Solenoid valve for shielding gas opens
• Welding voltage is applied on wire electrode
• Wire drive unit starts with reduced speed (inching-in)
• Arc ignites, welding current flows
• Wire drive unit switches to the preset wire speed
2nd cycle --> Release torch trigger
• Wire drive unit stops
• Welding voltage is switched off after expiration of the "burnback time"
• Arc extinguishes
• Solenoid valve closes after expiration of the "gas post-flow time"
