FREQUENTLY ASKED QUESTIONS / TROUBLESHOOTING
Question/Problem - Cause
Cause
The welding machine does not switch on:
• The power cord is unplugged;
• The "ON/OFF" switch is in the OFF position (0);
The flux-cored welding machine is on but does not
deliver enough welding current and the yellow LED
light (thermal protection) is lit:
• Overloaded appliance;
• The power supply voltage is higher than the
technical specifications and trips the overload
relay;
• The ground clamp is not well attached and is not
in contact with the workpiece;
Poor welding performance:
• The power cord or extension cord is too long,
which causes the welding current to decrease;
• The welding current is not adjusted to the
characteristics of the wire;
• The wire is damp and causes instability in the
welding arc;
• The welding current is very high for the diameter
of the wire used;

Solution
• Plug in the power cord;
• Set the "ON/OFF" switch to ON position (I);
• Wait for the machine to cool down and switch it
back on;
• Adjust to the appropriate supply voltage;
• Attach the ground clamp correctly and ensure it is
contact with the workpiece;
• Increase the cable cross-section of the extension
cord or decrease its length;
• Adjust the welding current on the wire tension
knob according to the wire used;
• Use a good-quality and dry wire;
• Adjust the welding current according to the wire
used;
