Frequently Asked Questions - MK-8988 MKC
What type of welding can the MK-8988 perform?
The MK-8988 supports MMA (stick) welding and Lift TIG welding. It is suitable for general metal fabrication and repair work.
What is the maximum welding current?
The maximum output current is 200A with a duty cycle of 60%. For continuous welding at lower currents, the duty cycle improves.
What power supply is required?
The machine requires a single-phase AC 220V power supply at 50-60Hz. Ensure the outlet is properly grounded and rated for at least 30A.
Can I weld aluminum with this machine?
Aluminum welding is possible using TIG mode with an optional high-frequency unit and AC capability. However, the MK-8988 is DC only, so it is not ideal for aluminum. For steel and stainless steel, it works well.
How do I adjust the welding current?
Use the digital control knob on the front panel to set the welding current. The current is displayed on the LED screen. For MMA welding, refer to the electrode diameter and material thickness recommendations in the manual.
What safety precautions should I take?
Always wear a welding helmet with appropriate shade, gloves, and protective clothing. Ensure proper ventilation. Disconnect power before maintenance. The machine includes overheating and over-current protection, but operator safety is paramount.
Does the machine come with welding cables and electrode holder?
Yes, the MK-8988 typically includes a pair of welding cables (about 3m each) with an electrode holder and a ground clamp. Check the package contents list in the manual.
How do I clean and maintain the welding machine?
Regularly remove dust from the ventilation slots using a dry cloth or compressed air. Inspect cables for damage. Keep the machine dry. For internal cleaning, refer to a qualified technician.
What is the warranty period?
MKC typically offers a 2-year warranty against manufacturing defects. Warranty terms may vary by region; contact your local dealer for details.
Where can I find spare parts or service?
Contact an authorized MKC service center or your local distributor. For minor parts like contact tips, check online retailers. Always use genuine parts to ensure safety and performance.
