- *Connect the welding wire to the wire feeding device, pay attention to insert the welding wire directly into the wire guide tube, and then press the welding wire well.
- Step 4– Connect the ground clip and output wire to the machine (Note that the method of installation is different from that of solid wire; refer to the following figure to install)
- Step 5-Clamp the ground clip to the workpiece, then start your MIG work.
MIG- FLUX 1.0 Mode(Request 1.0 flux cored wire, no need to connect any gas）
* All the steps are the same as FLUX 0.8 Mode, just request to use 1.0 flux cord wire.
TIG Mode（Use with Air Cooled Lift TIG Torch)
- Step 1– Press the blue button below the LCD display to select “LIFT TIG”
- Step 2– Adjust the current knob to increase the current
- Step 3-Connect the ground clip and TIG torch to the machine.
- Step 4– Put argon gas into the gun’s trachea

S7 MIG 200 Welder-FAQs
What is the ideal setting for MIG welding?
Settings depend on wire size and material thickness. For a 0.024″ wire, use 13–15 volts with 130–160 IPM wire speed. For 0.030″, use 15–17 volts with 75–100 IPM.
How much electricity does a MIG welder consume?
MIG welders typically use between 1,400 and 6,000 watts, depending on the machine and settings.
What metals are suitable for MIG welding?
MIG welding works well with steel, aluminum, copper, nickel alloys, and even dissimilar metals.
What voltage should I use for different thicknesses?
For 1 mm steel, use 70A at 13V. For 2.5 mm, use around 120A at 19V.
What is the recommended gas flow rate?
A general rule: use 1 liter/min of shielding gas for every mm of nozzle diameter (e.g., 16mm nozzle = 16 L/min).
How many amps does a 200A MIG welder draw?
At 220V, a 200A welder uses about 44,000 watts (or 44 kW).
What thickness of steel can a 200A MIG welder handle?
It can weld up to 5/16″ (about 8mm) steel with proper preparation.
Do MIG welders use AC or DC?
Most MIG welders, including the S7 MIG 200, operate on DC output for better control and stability.
What is the working principle of MIG welding?
It uses a constant voltage supply to create an arc between a wire electrode and the metal, while inert gas protects the weld from air.
What’s the best welding angle?
A travel angle of 15–30° is recommended, with a 90° work angle on flat surfaces.
