Basic Welding Technique

SAFETY

1.

Press (and hold) Trigger and contact area to

 

 

 

be welded with electrode wire to ignite arc.

 

2.

For a narrow weld, you can usually draw the wire in

 

 

a steady straight line,

 

 

this is called a stringer bead.

 

 

For a wider weld, draw the wire back and forth

 

 

 

 

across the joint, this is called a weave bead.

SETUP

 

 

 

3.

Hold Gun in one hand and the face shield in the

 

 

 

other. If a hands-free welding shield (not included,

 

 

BASIC

 

see Arc Ray Safety on page 3 for guidelines) is

 

used, then both hands can be used to control Gun.

 

 

 

4.

Direct the welding wire straight into the joint.

WELDING

 

This gives an angle of 90° (straight up and

 

down) for butt (end to end) welds, and an

 

angle of 45° for fillet (T-shaped) welds.

WELDING TIPS

MAINTENANCE

5.The end of Gun should be tilted so that wire is angled anywhere in‑between straight on and 15° in the direction you are welding. The amount of tilt is called the drag angle.

6.The welding wire should extend no more than 1/2″ past the tip.

This distance is called stickout or CTWD - Contact Tip to Work Distance.

Drag Angle

0-15°
