The KR350A MIG Welding Torch is a best-selling industrial welding accessory designed for heavy-duty applications including thick steel plate fabrication (6-12mm), shipbuilding, construction machinery maintenance, and automotive frame manufacturing, this torch delivers optimal shielding gas distribution and arc stability during MIG welding operations.
Key Features
Precision Gas Burner System: Copper alloy burner with 100-mesh filter and micro-adjustable flow regulator ensures uniform gas distribution (≤5% flow deviation).
350A High-Current Capacity: Achieves ≥2.5mm weld penetration on 12mm steel plates without preheating, with 400℃ heat-resistant burner.
Broad Welder Compatibility: Works with KR-series welders and mainstream industrial models (Lincoln Power Wave, Miller XMT) using 1.0-1.6mm solid wires.
Tool-Free Maintenance: Detachable burner head enables 60-second cleaning/replacement, with reinforced cable joints rated for 10,000+ bend cycles.
