Description
1. Power supply: Single phase 220V, 50/60Hz.
2. Professional MIG welding machine built with IGBT and digital signal processing. It supports single pulse, double pulse and intelligent synergic control, fitted with a 5‑inch LCD screen.
3. This MIG welder adopts advanced STT (Surface Tension Transfer) welding technology, a refined controlled short‑circuit transfer process that differentiates it from conventional MIG welders. It achieves extremely low spatter and minimal heat input during welding, effectively reducing workpiece distortion and post‑weld cleaning work. Compared with ordinary short‑circuit MIG, STT precisely controls the metal transfer cycle to prevent burn‑through, particularly when working on thin plates. It is widely used for pipeline root pass welding, sheet metal fabrication, tank production and automotive repair, delivering stable arc performance and premium weld quality for critical welding applications.
4. Supports saving and recalling up to 20 welding programs. Users can preset and store optimized parameters for different workpieces, materials and welding tasks for one‑click recall, eliminating repeated parameter adjustment. This ensures stable and consistent weld quality, cuts tedious setup time and greatly improves welding efficiency.
5. Multiple optional welding processes: MIG Synergy, MIG Single Pulse, MIG Double Pulse, High‑speed MIG Single Pulse, High‑speed MIG Double Pulse, high‑speed vertical welding, high‑speed root welding, high‑speed cold welding, TIG and MMA.
6. Energy‑saving and high efficiency, with efficiency improved by 35%.
7. Broad material compatibility: FeC, ER316, ER308, ER304, galvanized steel sheet, pure aluminum, aluminum alloys, AlSi5(4043), AlMg5(5356), CuSi3, etc.
8. Applicable wire diameter: 0.8–1.2 mm. Compatible with various welding filler metals.
9. Rich functions and safety protections: VRD, 2T/4T, Special 4T, SPOT welding, inductance adjustment, hot start, arc force, burn back, pre‑gas / post‑gas setting, over‑current protection, over‑voltage protection, thermal protection, gas check and wire check.
10. Equipped with a high‑performance wire feeder for smooth wire feeding, compatible with 5kg wire spools.
11. Features deep penetration and outstanding welding performance. It produces smooth, tidy weld seams with high mechanical strength and great durability. Low spatter, low fume and low noise, making it ideal for high‑standard welding projects requiring strict quality control.
