  • Page 5: Safety Warning

    SAFETY WARNING Security Definitions It indicates that neglecting safety warnings may result in serious accidents, even death or serious injury. It indicates that neglecting safety warnings may result in minor injury to personnel or property damage. It indicates that neglecting safety warnings may result in equipment failure or damage.
  • Page 6 Beware of Electric Shocks  Before welding, the yellow-green grounding wire in the power line must be grounded and the insulation of the welding cable must be ensured.  During welding operation, do not touch live parts such as workbench, welding parts, earth clamp, electrode holder or welding torches.
  • Page 7 Welding Sparks May Cause Fire or Explosion  Corresponding protective measures should be taken in the welding area to avoid fire caused by welding mars.  Do not carry out welding operations in degreasing, cleaning and spraying areas.  Do not weld gas-filled pipes, sealing grooves (boxes) and other devices, otherwise explosions or fires are likely to occur.
  • Page 8 Avoiding Electromagnetic Interference  Users should ensure that the welding power supply and other equipment in the environment do not produce electromagnetic interference, otherwise corresponding shielding and protection measures should be taken.  According to the manufacturer's suggestion, the power source should be connected to the main power supply line.
  • Page 9 unloaded from the power supply first. When moving the power source on the ground, it is necessary to fix the cylinder with a strap or chain to prevent dumping and injuring people.  If the wire feeder is hoisted by lifting lugs for welding, it is necessary to ensure that it is firm and insulated.

  • Page 10: Product Description

    PRODUCT DESCRIPTION The welding machine applies the most advanced inversion technology in the world. The principle of inversion is to transform the power frequency of 50Hz/60Hz into direct current and invert it into high frequency (50KHz) through high-power device IGBT, then perform voltage-drop and commutation with the output high-power D.C power supply via Pulse Width Modulation (PWM).

  • Page 12: Installation Instruction

    INSTALLATION INSTRUCTION The welding equipment is equipped with power voltage compensation device. It keeps the machine working normally when power voltage fluctuates ±15% of rated voltage. When using long cable, in order to reduce voltage drop, big section cable is suggested. If the cable is too long, it will affect the performance of arcing and other system functions, it is suggested to use the recommended length.

    PANEL FUNCTION ILLUSTRATION Multifunctional Data Display Data Selection Key Under MMA mode: can open or close VRD function by long pressing on the data selection key. Under MIG mode: can select parameters and choose the welding mode (2T/4T) by pressing the Data Selection Key.
  • Page 16 Operation instruction: 1） The starting up display Switch on the welding power source, the front panel displays as Fig.1. After the Multifunctional Data Display (or any key or knob on front panel) flashes for 5 seconds, the machine enters into the welding mode that saved in the last shutdown.
  • Page 17 Adjusting parameters: Under MIG mode, you can adjust the voltage, inductance and wire feeding speed. By default, you can adjust the wire feeding speed. Press the Data Selection Key for the first time, the Multifunctional Data Display shows as Fig.4, which means the welding voltage is adjustable, and the adjustment range of preset voltage is ±20%.
  • Page 18 “HOLD” flashes for 3 seconds and quenches, which means the welding stops. 2 seconds later, Multifunctional Data Display redisplays the preset current. Fig.8 The Status after Stop Welding under MIG Mode 3） Operation instruction under LIFT TIG mode. When welding stops, press the Function Switch Key to LIFT TIG mode. The LIFT TIG indicator light will illuminate (Fig.9).
  • Page 19 4） Operation instruction under MMA mode. Set welding mode: When welding stops, press the Function Switch Key to MMA mode，the SMAW indicator lights will illuminate. VRD function: Press the Data Selection Key for 3 seconds, the VRD reduces open circuit voltage to a safe limit and the function is enabled (Fig.11).
