at hand. The distance (if any) between the two workpieces must be controlled properly
to allow the weld to hold both sides securely while allowing the weld to penetrate
fully into the joint.
8. Set the desired welding current (30 to 200 Amps) for the type/thickness of metal
being welded, using the Wire Feed Speed Knob (3D) and Voltage Selector Knob
(2D). (See Figure P above, and Figure S, page 21.)
9. Make sure the Power Switch (4D) is in its “OFF” position. Then plug Power Cord
(1A) of the Welder into a dedicated, 220 VAC, 40 AMP line with delayed action type
circuit breaker or fuse. (See Figure P.)
10. While holding the Welding Torch (15E), with the Welding Wire clearly out of the way
of any grounded objects, turn the Power Switch (4D) to its “ON” position.
(See Figure P.)
11. Momentarily squeeze the Trigger Switch (13E) of the Welding Torch (15E) to test the
wire feed speed. If necessary, adjust the speed by turning the Wire Feed Speed
Knob (3D). (See Figure P.)
12. Orient yourself on the area to be welded, then place a Face Shield over your eyes.
WARNING! Never look at the ignited arc without ANSI-approved,
arc-shaded, eye protection in a full face shield. Permanent eye damage
or blindness can occur. Skin burns can occur. Never breathe arc fumes.
(See page 8.)
HOLDING THE WELDING TORCH
13. Hold the Welding Torch (15E) in one hand and the face shield in the other. If a
hands-free welding shield is used, then both hands can be used to control the
Welding Torch.
14. The Welding Wire should be directed straight into the joint.
This gives an angle of 90 degrees (straight up and down) for
groove (end to end) welds, and an angle of 45 degrees for
fillet (T-shaped) welds.
15. The end of the Welding Torch should be tilted so that the
Welding Wire is angled anywhere in between straight on and
15 degrees in the direction of the weld. The amount of tilt is
called the “drag angle”. (See Figure Q.)
16. The Welding Wire should extend no more than 1/2” past the
Nozzle (1.1D) of the Welding Torch (15E). This distance is
called “stickout”. (See Figure Q.)
17. Set the Wire Feed Speed Knob (3D) to the recommended start setting as shown in
the Weld Settings Chart on the next page. (See Figure S.)
