The full recording got cut off, but the first 1-2 HP bars are the simple phase. Pop the Ultimate early for a full shield meter if you want, but make sure Ult is up again for the last phase. Tips:

Focus on keeping your shield meter as high as possible even if you need to play slow. It's worth stalling a bit to make sure your ult is up again.
Save up Shield Charge for when you need to absorb a hit, you can use the 15% HP from that first rather than taking the damage directly to your shield meter.
Save Gunlance Counter to iframe the nasty beam attacks.
