BRIEF INTRODUCTION
ECN welder uses imported IGBT and fast recovery diodes as
main electric components. It is supplemented by a specially
developed main PCB board. In addition, the uniform regulation
of welding current has been designed to guarantee the arc
reach good welding process adaptability. What’s more, its
perfect dynamic protection features ensure that it is safe
and reliable when use. It is ideal for using low carbon steel,
stainless steel, alloy steel etc.
MMA Features:
• Lower cost operation, more portable, more compact,
superior output.
• Excellent arc properties and solution droplet transfer.
• With the protections of over-heating, over-voltage,
over-current.
• Plastic handle makes it easy to carry.
• Convenient quick connection for the output makes it quick,
safe, simple and stable.
NOTES: The above description may be modified without
prior notice such as omissions, unclear statements
about this welder.
SAFETY
Self-Protection
• The user must comply with occupational safety and
health rules and wear appropriate labor protective
equipment. Try to avoid injury on eye and skin.
• It is safe to cover your head with face mask while
welding, only do the observation on the arc through
the window of the mask.
• Don’t expose any part of the body at the same time to
the welding positive and negative output terminals
without insulated protection.

Cautions
• DC ECN Inverter DC Arc welder is a kind of electronic
product which makes its components more easily
damaged. While replacing or modulating, the strength
should not be too much in order to avoid causing
damage to the device.
• Check the connection to see if it is correct or reliable
each time before working. Besides, ensure
the grounding outlet device correct.
• While using, as smoke is harmful to human’s health,
the operation must be carried out in the ventilation
and exhaust facilities.
