SPECIFICATIONS

This MIG Welder is suitable for light duty industrial applications and is designed for low-carbon and 

low-alloy steels. It incorporates a wire feed system.  

Noise emission: 

≤ 75 dB

Overload light:

Welding for an extended period at high amperage may cause the overload lamp to illuminate and the 

welder to shut down. This is normal overload protection to prevent damage to the unit. If this should 

occur, turn the power switch to "OFF" and allow the unit to cool down for approx. 15 minutes.
