⚠WARNING
ELECTRIC SHOCK CAN KILL!
To prevent ELECTRIC SHOCK, do not perform any welding while standing, kneeling, or lying directly
on the grounded workpiece.
f. Finish the bead
As the coating on the outside of the electrode burns off, it forms an envelope of
protective gases around the weld. This prevents air from reaching the molten metal
and creating an undesirable chemical reaction. The burning coating, however, forms
slag. The slag formation appears as an accumulation of dirty metal scale on the
finished weld. Slag should be removed by using a chipping hammer.
⚠WARNING
PEENING THE SLAG FROM A WELD JOINT CAUSES SMALL CHIPS OF METAL TO FLY
THROUGH THE AIR!
Metallic chips flying through the air can cause eye injury or injury to other parts of the head, hands
or exposed portions of the body. Wear goggles or safety glasses with side shields and protect the
hands and other exposed parts of the body with protective garments, or if possible, work with a
shield between the body and the work piece.
Strain is created in the metal due to the intense heat the arc produces while welding.
Peening the weld not only removes the scale left behind in the welding but relieves
the internal strains developed by the heating and cooling process.
DC TIG OPERATION
⚠WARNING
High voltage danger from power source!
Consult a qualified electrician for proper installation of receptacle at the power source. This welder
must be grounded while in use to protect the operator from electrical shock. If you are not sure if
your outlet is properly grounded, have it checked by a qualified electrician. Do not cut off the
grounding prong or alter the plug in any way and do not use any adapter, other than the supplied
adapter, between the welder's power cord and the power source receptacle. Make sure the
POWER switch is OFF then connect your welder's power cord to a properly grounded 230 VAC
(220V - 240V), 60 HZ, single phase, 50 amp power source. If operating on 120V, attach the 120V
Adapter cord to the unit power cord and then connect the assembly to a properly grounded 120
VAC (110V-130V), 60 Hz, single phase, 25 amp power source.
⚠WARNING
EXPOSURE TO A WELDING ARC IS EXTREMELY HARMFUL TO THE EYES AND SKIN!
Prolonged exposure to the welding arc can cause blindness and burns. Never strike an arc or
begin welding until you are adequately protected. Wear flame-proof welding gloves, a heavy long
sleeved shirt, trousers without cuffs, high topped shoes, and an ANSI approved welding helmet.
