  • Page 1 V1.4 14.09.21 OPERATING MANUAL INVERTER SYNERGIC SEMI-AUTOMATIC MIG 2OOHD WELDING MACHINE ATTENTION! Before installation and start-up of the device, please read this manual 1. GENERAL NOTES Start-up and use of the device may only be performed after carefully reading this User's Manual.
  • Page 2 Due to the continuous technical development of the device, the external appearance and some of its functions may be modified and their operation may differ in details from the descriptions in the manual and on the carton. This is not a device error, but the result of progress and continuous modification of the device. The standard equipment of the device may also change.

  • Page 3: General Description

    3. GENERAL DESCRIPTION Synergistic MIG 200HD welder is used for manual welding of steel and non-ferrous metals. It enables welding with MMA (coated electrode), TIG Lift and MIG / MAG methods in synergic and manual mode. Thanks to the change of polarity, the device allows welding with the MIG / MAG method using both standard wires in a protective gas shield and self-shielding flux-cored wires.

    4. TECHNICAL PARAMETERS 4.1. Welding machine Supply voltage: AC 230V 50Hz Maximum power consumption: 6.6 kVA Rated welding current: / MIG duty cycle : 200A / 45%; MMA: 180A / 60%; TIG: 180A / 60% Nominal voltage in no-load condition 65 V Diameter of wire spools: 100mm, 200mm...
  • Page 5 Maximum current load: 200 A (CO Type of cooling: Cooling gas flow: 10-18 l / min Length: Work cycle The work cycle is based on a 10-minute period. Duty cycle of 45% means that after 4.5 minutes of operation, a 5.5-minute break is required.

    5.5 Preparing the MIG torch to work Depending on the type of material to be welded and the diameter of the electrode wire, attach a suitable contact tip and a wire guide to the MIG torch. For welding steel, use contact tips for welding steel and a steel insert. When welding aluminum, use contact tips for aluminum welding and a Teflon insert.

During MIG welding, pressing the button for 3 seconds will return to the initial parameters. C - Inductance adjustment / loading button for settings Press 3s to load Short press of the button will switch to inductance adjustment by means of the knob (D).

  • Page 13: Parameter Settings

    Press 3s to save The button is active only during MIG / MAG welding. It is used to select the welding mode control mode (two-stroke / four-stroke) and save the settings. Pressing the button briefly selects the device control mode. The selected control mode is confirmed by lighting up the corresponding LED.
  • Page 14 After switching the device on, it is possible to use the knob (D) to synergistically select the voltage and the corresponding welding current. The wire feed speed will be automatically adjusted to the set welding current. After initial setting of these parameters, manual correction of both welding voltage and current is possible. The transition between the adjustable parameters is done by pressing the knob (D).

Excessive wire tension may cause a feed problem. • Make sure the handle is equipped with a Teflon guide liner designed for aluminum. Using steel components used to feed the steel wire will cause feed problems.

  • Page 20: Maintenance Instructions

    MIG 200HD welder should be operated in an atmosphere free from corrosive components and large dust. Do not place the device in dusty places, near working grinders, etc. Dust and contamination with metal filings on control boards, wires and connections inside the device may lead to an electric short circuit and, consequently, damage to the welding machine.
