User Manual for GYS MULTIWELD 160M / 200M Welding Machine

Quick guide from the manual

The GYS MULTIWELD 160M and 200M are semi-automatic welding stations designed for MIG/MAG, flux-cored wire, and MMA welding. They are manual setting machines assisted by a reference table printed on the product. These machines are recommended for welding steel, stainless steel, and aluminum.

Safety Rules

Arc welding can be dangerous and cause serious or fatal injuries. Always wear protective clothing that covers the entire body, insulated gloves, and a welding helmet with sufficient protection. Ensure the working area is well-ventilated and free from flammable materials. Keep a safe distance of at least 11 meters from flammable objects. People with pacemakers must consult a doctor before using this equipment.

Installation

Place the machine on a floor with a maximum incline of 10°. Ensure the area is well-ventilated and free from conductive metal dust. The machine has an IP21 protection rating, meaning it is protected against solid objects larger than 12.5mm and vertically falling water drops. Ensure all power and welding cables are fully uncoiled to prevent overheating.

MIG/MAG Welding

Connect the earth clamp to the positive (+) or negative (-) terminal depending on the wire type. Select the MIG/MAG mode using the switch. Adjust the welding voltage and wire speed according to the reference table on the machine based on the thickness of the workpiece. The inductance can be adjusted to control arc hardness; lower inductance makes the arc harder and more directional, while higher inductance makes it softer with less spatter.

MMA Welding

In MMA mode, the polarity reversal cable must be disconnected. Connect the electrode holder and earth clamp to the connectors. Select the MMA mode using the switch. Adjust the welding current using the central knob based on the electrode diameter and type. The machine features an Anti-Sticking function to prevent the electrode from overheating if it sticks to the metal.

Maintenance

Maintenance should only be performed by qualified personnel. Annual maintenance is recommended. Regularly remove the casing to dust the interior with compressed air and have electrical connections checked. Ensure ventilation holes remain clear for proper airflow. If the power cable is damaged, it must be replaced by the manufacturer or a qualified service technician.

Troubleshooting

If the wire feed is not constant, check for debris in the contact tube, ensure the correct roller pressure, and verify the wire diameter matches the roller. If the machine has no welding current, check the mains connection and the earth clamp. If the weld bead is porous, ensure sufficient gas flow, clean the base metal, and protect the welding area from drafts.
