Why is the warning lamp lighting up on my Express Weld Welding System?
The warning lamp on the Express Weld Welding System might light up due to overheating from high welding current or prolonged operation. Try decreasing the welding current or taking breaks during welding. It can also indicate the activation of over current protection due to abnormal current in the main circuit.
How to fix an unstable arc on Express Weld Welding System?
Unstable arc in Express Weld Welding System can occur if the pole connections are incorrect or loose. Ensure the poles are correctly connected and tightened. Also, verify that the mains voltage is 380 Volts and that you are using an appropriate extension cord.
What to do if there is no current output in Express Weld Welding System?
If there is no current output in your Express Weld Welding System, first ensure the welding cable is properly connected to the machine's outlets. Also, check the welding cable for damage and replace it if needed. Finally, verify that the work cable is securely connected.
Why won't the arc start or are electrodes sticking to the workpiece with my Express Weld Welding System?
If the arc does not start or electrodes stick to the workpiece when using the Express Weld Welding System, check for loose or poor connections. Also, inspect the workpiece surface and clean it if it's dirty, oily, or dusty.
How to improve penetration with Express Weld Welding System?
If the penetration is not sufficient while using the Express Weld Welding System, the welding current setting might be too low. Increase the welding current value to improve penetration.
What to do if Express Weld Welding System doesn't work, has no output, and the fan isn't working?
If your Express Weld Welding System isn't working, has no output, and the fan isn't running, check the following: 1. Ensure there is electricity on the line and reconnect the phases if necessary. 2. Inspect the main input cable for defects and replace if needed. 3. Check the On/Off switch and replace it if defective.
What causes arc blow in Express Weld Welding System and how can I fix it?
Arc blow in the Express Weld Welding System can be caused by several factors: 1. Strong air flow: Use a protecting screen. 2. Welding electrode issues: Adjust the angle between the welding electrode and workpiece. 3. Magnetic field interference: Tilt the welding electrode to counter the arc blow, change the location of the work clamp or place grounding cable on both sides of the work piece, or use a short arc distance.
Why is my Express Weld Welding System vibrating?
The Express Weld Welding System may vibrate if it is not placed on a stable and straight surface. Ensure the machine is placed on a suitable surface.
What to do if the power light is on but the fan isn't working on my Express Weld Welding System?
If the power indicator lamp lights up but the fan doesn't operate on your Express Weld Welding System, check if something is jammed in the fan blades and remove it. Also, the fan capacitor or the fan itself may be faulty.
What to do if there is an abnormal noise and smell coming from my Express Weld Welding System?
An abnormal noise and smell coming from the Express Weld Welding System may indicate a problem with the cooling fan. Inspect the cooling fan.
