2. Your worktable should allow the work metal to be held firmly in place to prevent it from falling or moving accidentally. 3. The floor and surroundings of the work site should be non-flammable. A clean cement floor is recommended. The welding process will eject molten metal slag onto the floor, and this will spread over 8-10 feet or more in any direction.

MAINTENANCE WARNING Make sure the power switch on the welding machine is in the OFF position and the equipment is unplugged from the electrical outlet before performing any inspection, maintenance or cleaning procedures. 1. Before each use, inspect the general condition of the welding machine. Check for loose cable connections, fan misalignment or binding, cracked or broken parts, damaged electrical wiring and any other condition that may affect its safe operation.

Shielded metal arc welding (SMAW) Shielded metal arc welding (SMAW), also known as manual metal arc welding (MMA), flux-shielded arc welding or, informally, electrode welding, is a manual arc welding process that uses a consumable flux-coated electrode for welding. Electric current, either alternating or direct current from a welding power source, is used to form an electric arc between the electrode and the metals to be joined.

ELECTRICAL PARTS The 3-phase input voltage (220V/380V/440V) is rectified to HV DC power by the 3-phase rectifier (the rectified voltage is 1.414 times the 3-phase input voltage). To guarantee consistent input voltage for the full-bridge inverter circuit (guarantee consistent output voltage), we adopted a step-down chopper circuit, so whatever is the 3-phase input voltage, the input voltage for the full-bridge inverter circuit is 310V (the Min.
