AC/DC TIG WELDER - Harbor Freight Tools

Output Connections For A TIG Welding Process With DCEN:
Note: Always turn off the Welder before making connection changes.
DCEN = Direct Current Electrode Negative.
1. Raise the Front Cover (2) to expose the controls. (See Figure C.)
2. Connect the Welding Gun’s Power Cable (4A) to the Negative Terminal (51B).
Connect the Welding Gun’s Switch Cable (3A) to the 2-Pin Socket (50). Then,
connect the Welding Gun’s Gas Hose (2A) to the Gas Hose Outlet (52).
(See Figure C.)
3. Connect the Ground Clamp Cable (5A) to the Positive Terminal (51A).
(See Figure C.)
4. NOTE: The DCEN mode is for a narrow and deep weld penetration,
concentrating 70% of heat on the workpiece and 30% heat on the Welding Gun.
Output Connections For A TIG Welding Process With DCEP:
DCEP = Direct Current Electrode Positive.
1. Raise the Front Cover (2) to expose the controls. (See Figure C.)
2. Connect the Welding Gun’s Power Cable (4A) to the Positive Terminal (51A).
Connect the Welding Gun’s Switch Cable (3A) to the 2-Pin Socket (50). Then,
connect the Welding Gun’s Gas Hose (2A) to the Gas Hose Outlet (52).
(See Figure C.)
3. Connect the Ground Clamp Cable (5A) to the Negative Terminal (51B).
(See Figure C.)
4. NOTE: The DCEP mode is for shallow penetration and a strong cleaning action,
concentrating 30% of heat on the workpiece and 70% heat on the Welding Gun.
To Select The Welding Mode:
NOTE: This Welder features 4 welding modes.
1. AC MMA = The stick/electrode welding for mild steel. This is the simplest
welding procedure.
