Preparing for Welding
□
Designate a work area that is clean and well lit. Keep children
and pets out of the work area.
□
Read the user manual and safety guidelines before operating
the welder.
□
Ensure you understand the basic specification of your welder.
□
Wear PPEs to protect your eyes and skins from hot welding
sparks and intensive arc rays. Ensure same protections are
provided to any bystanders nearby.
□
Ensure all the combustible, flammable, hazardous substances
are removed from the work area. Make sure a fire extinguisher
within reach is available.
□
Inspect your welder before each use and do not operate a
welder with damaged cables and components. Replace all the
damaged parts before use. Have a qualified technician help you
if needed.
□
For flux core wire, shielding gas is not required.
□
For solid core wire, shielding gas is required. Check the
"Connecting the Gas Cylinder" instruction for more details.

Connecting the Gas Cylinder
□
Always make sure your gas cylinder is fully closed (turned
counterclockwise) when not welding or moving the cylinder.
□
Before welding, make sure your gas cylinder is securely fixed
to a wall or a steady workbench. Hitting by falling gas cylinder
can cause severe injury. Dropping gas cylinder can cause
hazard.
□
Turn the regulator adjustment knob counterclockwise to ensure
the gas regulator's valve is fully closed.
□
Connect one end of the gas regulator with the gas cylinder.
□
Attach the other end of the gas regulator with a gas hose.
□
Connect the other end of gas hose to the gas input (N) on the
back of the machine.
□
Make sure all connectors are tightened or sealed.
□
Open the gas cylinder valve and set the gas flow to
approximately 21-40 cu ft/h on the regulator.
□
Press the gun trigger to ensure that the gas is flowing through
the gun.
WARNING: Welding processes generate high-
temperature arc, welding sparks, hot slag and hot
spatters. Welding arc generates extremely intense
ultraviolet and infrared light. Failure to wear
protective equipment during welding can severely
damage your eyes and burn your skin.
WARNING: Failure to protect combustible materials
against welding sparks, hot slag and hot spatters
can cause fire and even explosion. Fire and
explosion can cause death, injury and property
damage.
