Page 16 3. OPERATION 3.1 Performance Data Plate And Duty Cycle On the machine, there is a plate that includes all the operating speciﬁcations for your new unit. The duty cycle rating of a welding machine deﬁnes how long the operator can weld and how long the welding machine must rest and be cooled. Duty cycle is expressed as a percentage of 10 minutes and represents the maximum welding time allowed.
Page 17 3.3 Welding Preparation The key to making a good weld is preparation. It includes studying the process and equipment and practicing welding before attempting to weld the ﬁnished product. An organized, safe, ergonomic, comfortable, and well-lit work area should be prepared for the operator.
Page 18 3.7 Setup for Home Menu After powering on the machine and the startup screen appears, use the Home Menu button to navigate to the main menu. From there, users can choose the welding mode (MIG/MAG, Flux-cored, TIG, Stick) and adjust the machine’s basic settings. Note: The machine is tested before shipment.

Page 31 1. Material Selection: Only Steel available. 2. Wire Diameter Selection: Select the appropriate wire diameter based on the material thickness and welding application. Available options include wire diameters typically ranging from 0.8mm to 1.2mm (.030"~.045"). 3. Thickness Selection: Adjust the thickness setting to match the workpiece’s thickness (24ga~3/8"). This setting ensures proper heat input and weld penetration, providing a solid and consistent weld bead.
Page 32 This section provides instructions on connecting the welding machine and spool gun. The connection setup varies depending on the welding process, such as MIG/MAG or Flux. The machine is compatible with the optional YesWelder LBT150 spool gun or any compatible Euro-connect spool gun with two-pin control cable from other brand.
Page 33 Below is a basic guide for the spool gun installation. Follow the steps as shown in the image to ensure proper setup and optimal performance. 1.

Page 35 3.12.2 2T/4T/SPOT Advanced Parameter Details for GMAW and FCAW In 2T/4T/Spot torch trigger operations, the speciﬁc parameters are as follows: Inductance: Controls arc dynamics. Higher values smooth the arc and reduce spatter, while lower values increase penetration. Ÿ Ideal for managing the weld pool, especially for thin sheets or stainless steel. Pre-ﬂow Time: Sets the duration for shielding gas release before arc initiation to protect the weld area from oxidation.

Page 41 Setting up the Equipment for TIG Welding (GTAW): The TIG torch is not included with the machine. For optimal perfor- mance, we recommend using the additional YesWelder WP-17V-35 Lift TIG torch and Lanthanated Tungsten electrodes. WARNING: TIG TORCH IS ALWAYS LIVE (ELECTRICALLY HOT). Use caution and ensure the TIG torch is not in contact or close to a conductive or grounded material.
Page 42 Set the tungsten electrode to extend approximately 1/4 inch from the gas cup. Ensure you are using the correct size and type of Ÿ tungsten electrode. Smaller electrodes are suitable for lower welding currents. The tungsten must have a sharpened tip for direct current (DC) welding.

Thickness Selection: Pick the appropriate material thickness from 24ga to 3/8". The selected thickness corresponds with weld- ing amperage and electrode diameter.
Page 52 Hot Start – Adjustable Parameter: Hot Start improves arc ignition by brieﬂy increasing the welding current when starting the weld, reducing the risk of the electrode sticking to the workpiece. Importance: This feature is particularly useful in conditions where materials have poor surface conditions, electrodes are damp, or when welding with difﬁcult-to-start electrodes.
Page 53 3.15 Setup for Memory Saving and Loading The Memory function allows users to store welding parameters such as voltage, wire feed speed, and amperage settings under des- ignated memory channels. These stored settings can be easily recalled, adjusted, and saved as needed for future use. The system supports up to 50 memory slots for MIG/MAG welding, and 20 slots for Flux-cored, TIG, and Stick welding, ensuring quick access to optimized parameters for various welding applications.
