Durable, sturdy and lightweight, this economical MMA welder can makes your daily welding chores a bit easier. Known for its excellent electric arc, this MMA welding unit is often used in the argon welding process. High duty cycle allows the arc welder to use various diameters of electrodes. IP23 rating means our MMA welder can function properly under unfavorable working conditions.
Advanced inverter technology enables high welding efficiency and power factor. Using our MMA welder means saving electricity and reduce welding cost. Complete welding functions also gives the welder great flexibility.
Model ARC-315 and ARC-400 can be powered by an electric generator. They can use cellulosic electrodes to perform welding, which make them suitable for outdoor welding applications.
Features
1. The use of IGBT technology greatly simplifies the structure of the welding unit, allowing the welder to be carried around easily and effortlessly. Model ARC-120 and ARC-140 only weigh 3.8kg each. Simple operation makes the welder perfect for home use.
2. High igniting current makes the welder easy to produce electric arc. Small but stable welding current avoids sticky electrode and creates deeper welds. All these factors contribute to a clean, attractive weld surface.
3. In welding, a high igniting current is used to ignite or strike the current. This way of arc ignition can cope with many welding applications.
4. High inverting frequency allows the welder to improve welding efficiency up to 85%.
5. Smart protection system protects our MMA welder from damages caused by over-voltage, low-voltage, over-heat, and over-current. It increases the use life of the welding unit.
6. The circuit board is coated with insulation paint to prevent corrosion from humidity or corrosive gas. This avoids machine breakdown resulting from faulty circuit board.
7. Low-voltage compensation technology allows the MMA welder to be connected to an electric generator.
8. Suitable for use with ordinary electrode and flux-cored electrode.
