• Frequently Asked Questions:

Q1: How long can the YMTH2.5 rechargeable battery powered welder work on a single charge?

A: With its premium 2500Wh high capacity battery, the welder can continuously burn approximately 35 to 40 pieces of 3.2mm (1/8") welding rods, or run for about 4-5 hours under normal intermittent maintenance welding conditions.

Q2: Is a battery operated welding machine safe to use in damp or outdoor environments?

A: Yes, the YMTH2.5 is engineered as a safe and reliable portable welder. Built-in battery management systems (BMS) offer comprehensive protections against short-circuits, overheating, over-voltage, and over-current. However, we always recommend avoiding direct operation in heavy rain for maximum operator safety.

Q3: How long does it take to fully charge the 2500Wh welder battery?

A: Using our included high-current fast charger, it takes approximately 3 to 4 hours to charge from 0% to 100%. The smart LCD screen will display real-time charging progress and battery health status.

Q4: What welding modes and materials does the YMTH2.5 support?

A: This versatile machine supports stick (MMA) and TIG welding modes. It delivers a stable, smooth arc perfect for welding carbon steel, stainless steel, alloy steel, and copper plates.

Q5: What is the estimated lifespan of the built-in lithium battery?

A: We use advanced, industrial-grade lithium cells that deliver over 2,000 complete charge-discharge cycles. Even after years of daily heavy use, the battery will retain over 80% of its original capacity.
