i-WELD GMAW 220D

Description

GMAW 220D

• Single phase.
• Robust & high quality.
• Good ignition.
• Good price/quality/ratio.

New Design Digital Control System

• PWM control wire feeder, more stable ARC.
• Easy check, easy maintain.
• CPU control, strongly anti-interfere ability.
• Wire start adjust, good ARC ignition, suitable for aluminium welding.

Advanced MOS Control PWM Wire Feeder Technology

	Work voltage for traditional SCR wire feeder unit	Work voltage for DIGITAL MIG series wire feeder unit
Low voltage condition
High voltage condition
Wire feed stability	worse	good
Anti-interfere ability	worse	good
Respond	worse	good
Arc performance	worse	good
Remark	traditional SCR control, instability voltage, inferior anti-interfere ability	MOS PWM closed circuit control, stability voltage, good anti-interfere ability, more stable arc
