SAFETY

Grounding

TO PREVENT ELECTRIC SHOCK AND DEATH

FROM INCORRECT GROUNDING WIRE CONNECTION:

Check with a qualified electrician if you are in doubt as to whether the outlet is properly grounded. Have a plug installed by a certified electrician.

Do not use the welder if the power cord or plug is damaged. If damaged, have it repaired by a service facility before use. If the plug will not fit the outlet, have a proper outlet installed by a qualified electrician,

do not use adapter plugs.

SETUP

BASIC WELDING

1.The green wire inside the cord is connected to the grounding system in the welder. The green wire in the cord must be the only wire connected to the welder’s grounding system and must never be attached to an electrically “live” terminal. Never leave the grounding wire disconnected

or modify the Power Cord Plug in any way.

2.Make sure the tool is connected to an outlet having the same configuration as the plug. If the tool must be reconnected for use on a different type of electric circuit, the reconnection should be made by qualified service personnel; and after reconnection, the tool should comply with all local codes and ordinances.

3.A 250 V~ plug will need to be installed by a certified electrician before use.

4.The plug shown (NEMA 6-50p) is for use on a

50 A circuit. A different 250 V~ plug and outlet combination may be used, provided it is rated to handle the electrical requirements of the tool and is installed by a certified electrician.

DO NOT USE 125 V~ PLUG.

NOTE SIZE DIFFERENCE.

250 V~ 3-Prong Plug (6-50p) and Outlet (6-50r)

(for up to 250 V~ and up to 50 A)
