Electronic products due to the production process and transport, there will be some defect rate, unfortunately, if you receive a defective product, please contact us first to resolve it, we will promptly return or refund to you Size: ARC-225 ARC-225 is an advanced arc inverter welding machine. The welding machine is controlled by an intelligent circuit board with IGBT, which can start arc immediately, with less spatter and smooth welding seam. The mini body allows us to carry it with us, and low power consumption and efficient heat dissipation allow us to work perfectly all day. Specification: Applicable electrode: diameter 1.6-2.5mm Input voltage: AC 110V +/- 15% Frequency (HZ): 50/60 Rated input current: 23.5A No-load voltage: 65V Output current: 20-225A Output voltage: 25.6V Efficiency: 85% Power factor: 0.73 No-load loss: 40w Unit size: 25 * 10.5 * 18 The package includes: 1x arc welding machine 1x electrode holder 1 ground clip 1x mask(if the glass in broken please contact us exchange it) 1x brush (for cleaning welding spatter) 1x Manual (English)
