Welder use and care

1.Do not use the welder if the switch does not turn it on and off. Any welder that cannot be controlled with the switch is dangerous and must be repaired.

2.Disconnect the plug from the power source before making any adjustments, changing accessories, or storing welders. Such preventive safety measures reduce the risk of starting the welder accidentally.

3.Prevent unintentional starting.

Ensure the switch is in the off-position before connecting to power source or moving the welder. Carrying or energizing welders that have

the switch on invites accidents.

4.Store idle welders out of the reach of children and do not allow persons unfamiliar with the welder or these instructions to operate the welder. Welders are dangerous in the hands of untrained users.

5.Use the welder and accessories in accordance with these instructions, taking into account the working conditions and the work to be performed. Use of the welder for operations different from those intended could result in a hazardous situation.

SAFETY

SETUP

Maintenance

1.Maintain welders. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the welder’s operation. If damaged, have the welder repaired before use. Many accidents are caused by poorly maintained welders.

2.Have your welder serviced by a qualified repair person using only identical replacement parts. This will ensure that the safety of the welder is maintained.

3.Maintain labels and nameplates on the Welder. These carry important information.

If unreadable or missing, contact Harbor Freight Tools for a replacement.

4.Unplug before maintenance. Unplug the Welder from its electrical outlet before any inspection, maintenance, or cleaning procedures.

BASIC WELDING

Gas Shielded Welding - Cylinder safety

Cylinders can explode when damaged.

TIPS

1.Never weld on a pressurized or a closed cylinder.

2.Never allow an electrode holder, electrode, welding torch, or welding wire to touch the cylinder.

3.Keep cylinders away from any electrical circuits, including welding circuits.

4.Keep protective cap in place over the valve except when the cylinder is in use.

5.Use only correct gas shielding equipment designed specifically for the type of welding you will do. Maintain this equipment properly.

6.Protect gas cylinders from heat, being struck, physical damage, slag, flames, sparks, and arcs.

7.Always use proper procedures to move cylinders.
