Part 3: How to Select the Right Model Based on Application
一看板厚，二看工地，三看续航需求。板厚决定最小电流，工地条件决定防护要求，续航需求决定油箱大小。双把机型优先推荐 —— 效率翻倍，摊薄成本。
Core selection rule: 1) Plate thickness → minimum current; 2) Site conditions → protection rating; 3) Duty cycle → fuel tank size. Dual-torch models are strongly recommended — double efficiency, lower per-weld cost.
