Is the FEIFANKE ARC140 Mini Welder the right choice for users who need a reliable, portable machine?
⚡ At a Glance
- • Welding Performance: Stable arc with deeper penetration, suitable for electrodes 1.6–3.2 mm and 20–140A output
- • Best for: DIYers and tradespeople needing a compact, site-ready MMA and Lift TIG solution
- • Not ideal for: Continuous heavy industrial welding that requires sustained currents above 140A
MCU-controlled IGBT inverter delivers smoother welding and stable current. Ultra-compact form factor with built-in safety protections suits on-site and workshop use.
Easy to transport and store - with ultra-compact 2.1kg chassis and strap
Measures 210 x 130 x 90 mm and weighs 2.1 kg, supplied with a carry strap for simple handling. Compact construction keeps footprint small for van storage or a crowded bench.
Lightweight build reduces fatigue during site work and slips easily into a toolbox or rucksack. Quick to move between jobs, helping get repairs finished faster.
Smooth, consistent arc for cleaner welds - thanks to MCU-controlled IGBT inverter and hot start
MCU-managed IGBT inverter converts AC to stable DC, controlling output precisely across the 20–140 A range. Adjustable hot start and arc force settings support easier ignition and maintain arc stability.
Easier electrode ignition and a steadier arc lead to fewer starts and stops, producing cleaner welds. Deeper penetration supports reliable joins on common steels using recommended electrodes.
Safer operation and longer life - with comprehensive protection and energy-efficient design
Built-in safeguards include overcurrent, overheat, overvoltage and undervoltage protection; digital VRD functionality is included. IGBT topology and quality cabling reduce power loss and thermal stress.
Protection circuitry cuts downtime and helps extend service life under typical site conditions. Energy-efficient operation keeps running temperatures lower and reduces strain on supply circuits.
