Possible causes of welder failure and troubleshooting methods
Transformer overheating 1. overload 2. transformer winding short circuit 1. reduce the welding current 2. eliminate short circuit faults
Welding current too low 1. secondary power line too long and too thin (line voltage drop too large) 2. secondary power coil loop (inductance too large) 3. poor contact of secondary power line (contact resistance at connection too large) or poor contact with overproduction. 1. shorten the length or enlarge the area. 2. Eliminate loops. 3. Reconnect to reduce contact resistance.
Welding current is too high or too low 1. Insulation damage in induction circuit (resulting in excessive current) 2. Eddy currents in magnetic circuit (resulting in reduced current) 1. Repair insulation damage 2. Adjust core gap
Welding power supply is overheated 1. entire wire is overheated: cross sectional area of wire is too small 2. connection is overheated: contact resistance at the connection is too high 1. replace the wire with a larger area 2. reconnect and reduce the contact resistance
Sudden increase in welding current and instability of the moving iron core during welding. Fix the adjusting handle or moving iron core
Brake screw or spring for loosening the brake nut or adjusting the spring pressure during welding
