1. BRIEF INTRODUCTION
CALAF 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.
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 and belt makes it easy to carry.
• Convenient quick connection for the output makes it quick, safe, simple and stable.

• Don't expose any part of the body at the same time to the welding positive and negative output terminals without insulated
protection.
2.2 cautions
• CALAF Inverter DC Arc welder is a kind of electronic product which makes its components more easily damaged. While repla-
cing 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.
• Prohibit non-professionals to change or replace the welder.
• Since the welder owns strong electromagnetic and radio frequencies, the people with cardiac pacemakers affected by the
interference electromagnetic, electrical frequency are not allowed to stay nearby.
• When it works, please pay attention to its rated duty cycle. Do not overload.
