Figure 5.1: Wire feed mechanism for MIG welding. - For gas welding, connect the gas tube from your shielding gas cylinder (e.g., CO2 or Argon/CO2 mix) to the Air Inlet on the rear panel.
- For aluminum welding, ensure the MIG torch has a graphite wire feed tube installed.
5.2 MMA (ARC) Welding Setup
- Connect the Electrode Holder to the positive (+) output terminal.
- Connect the Earth Clamp to the negative (-) output terminal.
- Insert the welding rod into the electrode holder.
5.3 TIG Welding Setup
- Connect the TIG torch (WP-17V type) to the negative (-) output terminal.
- Connect the Earth Clamp to the positive (+) output terminal.
- Connect the gas tube from your Argon shielding gas cylinder to the TIG torch's gas inlet (if applicable for your TIG torch model).
6. Operating Instructions
The MIG200II offers multiple welding modes with synergy control for ease of use.
6.1 Power On/Off
Flip the ON/OFF switch located on the rear panel to power on or off the machine.
6.2 Mode Selection and Synergy Control
Use the mode selection buttons on the front panel to choose between MIG, MMA, or TIG. The synergy control technology (Syn) automatically adjusts voltage and wire speed when you set the current, simplifying operation, especially for beginners.

6.3 MIG Welding (Gas/Gasless)
- Wire Diameter: Supports 0.6mm, 0.8mm, and 1.0mm flux cored or solid cored wire.
- Wire Roll: Accommodates 1KG/5KG wire rolls.
- Welding Thickness: Suitable for materials over 0.8mm thick.
- Mixed Gas MIG: For welding with mixed gas (e.g., 82% Argon with 18% CO2), select MIG mode and 0.8mm wire. This reduces spatter and improves weld quality.
- Aluminum Welding: Ensure the MIG torch is equipped with a graphite wire feed tube for optimal aluminum welding performance.
6.4 MMA (ARC) Welding
- Welding Rods: Use 2.5mm, 3.2mm, or 4.0mm welding rods.
- Welding Thickness: Suitable for metal thickness from 1.0mm to 12mm.
- Anti-stick: The machine features an anti-stick function to prevent the electrode from sticking to the workpiece.
6.5 TIG Welding
- TIG Torch: Use a WP-17V TIG torch for TIG welding.
- Welding Thickness: Suitable for materials from 1.0mm to 6.0mm thick.
7. Maintenance
Regular maintenance ensures the longevity and optimal performance of your welding machine.
- Cleaning: Periodically clean the machine's exterior and internal components (with compressed air) to remove dust and debris. Ensure power is disconnected before cleaning.
- Cable Inspection: Check all welding cables, torch, and earth clamp for wear, damage, or loose connections before each use. Replace damaged components immediately.
- Wire Feeder: Keep the wire feeder mechanism clean and free of debris. Ensure the wire pressing wheel and wire feeding wheel are functioning correctly.
- Gas Connections: Verify gas tube connections are secure and free of leaks (if using shielding gas).
- Storage: Store the welder in a clean, dry environment when not in use.
8. Troubleshooting
If you encounter issues with your MIG200II welder, refer to the following common troubleshooting steps:
| Problem | Possible Cause | Solution |
|---|---|---|
| No power | Power switch off, power cable disconnected, circuit breaker tripped. | Turn on power switch, check power cable connection, reset circuit breaker. |
| No arc in MMA/TIG | Loose connections, incorrect current setting, faulty electrode/tungsten. | Check all cable connections, adjust current, replace electrode/tungsten. |
| No wire feed in MIG | Wire tangled, wire feeder clogged, incorrect wire speed, contact tip blocked. | Check wire spool, clean wire feeder, adjust wire speed, clean/replace contact tip. |
| Poor weld quality | Incorrect settings (current, voltage, wire speed), improper technique, contaminated workpiece, wrong shielding gas. | Adjust settings, improve technique, clean workpiece, use correct shielding gas. |
If the problem persists after following these steps, contact qualified service personnel.
