When contacting support, please have your order number or product model name ready.

A: Don't worry — this is a common issue, and it's almost always caused by a simple setup or connection problem. Please follow these steps in order to diagnose and solve it:Step 1: Check Your Welding Technique (The Most Common New User Issue)For MIG welding, the arc will only start when the contact tip of the gun is touching or very close to the workpiece. If you pull the trigger with the gun held in the air, the wire will feed but there will be no arc.Quick Fix: Ensure you are pulling the trigger only when the contact tip is in direct contact with a clean spot on the metal you intend to weld.Step 2: Inspect Your Ground Connection (The Second Most Likely Cause)A poor ground (work clamp) connection will prevent the circuit from completing, stopping the arc.What to do:

1. Ensure the ground cable is tightly secured at the clamp.
2. Attach the clamp to a clean, bare metal spot on your workpiece or worktable. Scrape off any paint, rust, or coating at the attachment point.
3. A good test: if the clamp feels hot during an attempt, the connection is poor.

Step 3: Verify Machine Polarity & Internal Connections (According to our technical support data, incorrect wiring is a leading cause of this problem.What to do:

1. Refer to your welder's manual for the correct polarity setup diagram for your specific welding process (MIG, Flux-Cored, etc.).
2. Double-check that the MIG gun and ground cables are connected to the correct positive (+) and negative (-) terminals on your machine.
3. Ensure all connections inside the machine (if accessible per manual) and at the gun are tight and secure.

Still having issues?If the problem persists after checking all the above, please contact support@yeswelder.com with your machine model number and a description of your setup. We’ll be happy to help you troubleshoot further.

This is typically caused by an issue with the wire feeding mechanism. First, check if the wire spool is empty and replace it if necessary. If the spool has wire, the problem may be with the drive roller pressure. Adjust the pressure on the drive roller, as having either too little or too much pressure can prevent the wire from feeding correctly.

A: Follow this checklist:

1. Verify External Power: Plug another device into the same outlet to confirm it's active.
2. Check Machine Connections: Ensure the power cord is fully plugged into both the wall and the welder, and that the main power switch is ON.
3. Inspect Circuit & Outlet: Reset any tripped circuit breaker. Do not use a GFCI outlet, as it will nuisance-trip.
4. Confirm Voltage: Check the machine's INPUT VOLTAGE indicator. If it's off or shows abnormal voltage, have a qualified electrician check your outlet's power.

Still no power? Please contact support@yeswelder.com with your model number for further assistance.

A: This is a common mechanical issue. Please follow these steps in order to resolve it:

Step 1: Check the BasicsFeeding Path: Ensure the MIG gun liner and wire guide tube (if applicable) are properly installed and connected to the machine.Size Match: Verify that the drive roller groove type/size, welding wire diameter, and contact tip size are all the same (e.g., all 0.030” or 0.8mm). A mismatch here is a frequent cause of jams.

Step 2: Adjust Drive Roller PressureThe drive roller pressure is critical. Both too high and too low pressure can cause issues.Adjust it correctly: The pressure should be just enough to grip and feed the wire without crushing it. You should be able to briefly pinch and stop the wire with your gloved hand while the motor runs. If you can’t stop it, pressure is too high. If the roller slips, pressure is too low.

Step 3: Inspect & Clear ObstructionsContact Tip: Check if the contact tip is clogged with spatter or worn out. A damaged tip will restrict wire movement. Replace it if necessary.Wire Condition: Cut off any bent or damaged wire at the end. Ensure the wire on the spool is not tangled.Liner & Roller: Check that the drive roller retaining pin/screw is in place and secure. If problems persist, the gun liner may be kinked or clogged—try cleaning it with compressed air or replacing it.

Step 4: Verify Mechanical PartsInspect the drive roller for excessive wear and ensure it is locked in the correct position for the wire size.Confirm that the wire spool brake (if present) is not overtightened.Still having issues?If the problem continues after all checks, please contact support@yeswelder.com with your machine model and a photo/video of the issue for further assistance.

This occurs when the wire melts back and fuses to the tip. To resolve this, first, ensure your wire feed speed is not set too low for your voltage and increase it if necessary. Next, check that your stick-out (the wire extension past the tip) is not too short; increase the distance slightly. Finally, verify you are using the correct size contact tip and replace it if it is clogged or damaged.

This is a safety-related issue caused by a high-resistance connection, often due to a bad or loose ground. To fix this, first, ensure the connection between the ground clamp and the workpiece is on a spot of clean, bare metal, free of paint or rust. Then, check and tighten all cable connections, including where the ground cable attaches to the clamp and where both the ground and welding cables connect to the machine. A loose connection at any of these points will generate excessive heat.

This occurs when electrical current jumps from the nozzle to the workpiece instead of through the wire. The most common cause is a buildup of spatter or slag inside the nozzle, which can create a conductive path. To resolve this, turn off the machine, allow the gun to cool, and thoroughly clean the nozzle. If the nozzle is damaged or heavily clogged, it should be replaced.

Q: Why does my circuit breaker keep tripping when I use the welder?

A: Frequent breaker trips are usually caused by an electrical setup issue, not a machine fault. Follow these steps to identify the cause. For your safety, if you are unsure about electrical work, please consult a qualified electrician.

Scenario 1: Trips ONLY during welding (machine can restart)This typically points to an overloaded circuit. Check these points in order:

1. Circuit Capacity: This is the most common cause. Verify that your breaker matches your welder's minimum required amperage (e.g., 45A for 220V). Using a smaller breaker will cause it to trip.
2. Dedicated Circuit: Ensure the welder is plugged into a dedicated outlet on its own circuit, not shared with lights, tools, or other equipment.
3. Wire & Workpiece: - Use the smallest recommended wire diameter (e.g., 0.030") to reduce load. - Clean your workpiece. Welding on rusty, painted, or dirty metal increases resistance and can cause a higher current draw.

Scenario 2: Trips instantly & will NOT power back onIf the breaker trips immediately when turning the welder on (or it won't turn on at all after a trip), this may indicate a different issue.

1. First, try a different, known-good outlet on a sufficiently rated circuit to rule out a problem with your original wiring.
2. If the problem persists on a proper circuit, there may be an internal fault. Please contact support@yeswelder.com with your Order Number and a video/photos of the issue for further diagnosis.Need help with your wiring?

Installing the correct breaker or dedicated circuit must be done by a qualified electrician.

This fault code indicates an overcurrent condition has been detected by the machine. To resolve this, first check the input power connection to ensure it is secure and matches the machine's required voltage specification.

This fault indicates the machine has exceeded its duty cycle and the thermal protector has engaged due to overheating. To resolve this: Allow the welder to cool for at least 10 minutes with the power ON (the FAULT/THERMAL OVERLOAD indicator will turn off automatically when the machine has cooled sufficiently). Simultaneously, check for any obstructions blocking the air vents and ensure there is at least 12 inches of clearance on all sides of the machine for proper airflow. Always observe the rated duty cycle to prevent recurrence.

For the issue, we appreciate your kind assistance. Please kindly do the following and let us know:If there's a test button, please check if it works. (Note: Make sure it is in welding mode)

1. Adjust the sensitivity to the max, and adjust the delays and shades.
2. Test the battery if it is dead. (Normally, it's 3V)
3. Make sure the battery is put inside correctly.
4. Clean the lens in case it is dusty and dirty.
5. Welding helmet is only possible darkening when welding or under a tungsten bulb, it can not be tested by lighter or warm light bulbs.

auto-darken on the very first use or after some period of use.If it happened on the first use: Check if the battery has power and make sure it is fully charged.If it happened after a period of use: Check whether the sensors are blocked by welding spatter or dust. If spatter accumulates on the light sensors, it may prevent them from detecting the arc properly, causing the auto-darkening function to fail.

1. Check if you have selected the spool gun option?
2. Short the two pin for torch connector, and check if the motor work or not?
3. Press the inching to see if the wire feeding motor work or not?

• Wire Feeds Slowly or Erratically During Welding

1. The wire feeding may not be smooth. Ask cx to check whether the wire feeding wheel is worn or the wire feeding machine handle is not pressed properly, resulting in unstable wire feeding.
2. Check whether the wire on the wire reel is stuck.
3. The wire guide tube in the welding gun may be blocked by welding wire or welding wire iron filings, resulting in the welding wire not being able to be fed normally. ---Change the gun or wire feeding tube
