TEH TWA280 MMA 140A Inverter Stick Welder | IGBT DC | Digital Display | Wide Voltage 160-270V | CE Certified | Home & Workshop

The TEH TWA280 is a compact, professional-grade IGBT inverter MMA (Manual Metal Arc / Stick) welder delivering up to 140A of DC output current. Built for home workshops, garages, site work, and light professional fabrication, it combines the reliability of IGBT inverter technology with a wide input voltage tolerance of AC160-270V — performing consistently even on sites and locations with fluctuating or unstable power supplies.

With a digital current display, dual adjustment dials, arc force control, and standby mode, the TWA280 packs professional-level control features into a compact, portable unit that can be taken anywhere.

CONTROL PANEL FEATURES:

• Digital current meter display — see exact output current at a glance
• Current adjustment dial (20-140A range) — precise control for different materials and electrode sizes
• Arc force adjustment dial — fine-tune arc characteristics to suit electrode type and welding position
• IGBT indicator — confirms inverter technology is active
• DC output indicator — confirms DC arc for cleaner, more stable welds
• Power indicator light (green) — confirms unit is live

MMA WELDING EXPLAINED: MMA (Manual Metal Arc) welding — also known as stick welding — uses a consumable flux-covered electrode and a ground clamp. A short circuit is made on the workpiece to initiate the arc, and the electrode melts to form the weld. It's the most versatile and widely used welding process — suitable for mild steel, stainless steel, and cast iron in almost any environment including outdoors and on site.

PERFECT FOR:

• Home workshop and garage fabrication
• Site and maintenance welding
• Mild steel, stainless steel and cast iron
• General repair and fabrication work
• Beginners learning to weld
• Professionals needing a lightweight portable backup machine
• Fencing, gates, and garden metalwork
• Automotive repair and restoration

⚠️ SAFETY REMINDER: Always wear an appropriate auto-darkening or fixed shade welding helmet, welding gloves, and flame-resistant clothing when welding. Ensure adequate ventilation — welding produces fumes that are harmful if inhaled. Never weld near flammable materials. Ensure the workpiece is properly earthed before starting.
