PULL ≤15°

VERTICAL

GUN

YES

Problem: Gun is not being held vertical from side

to side. Wire is not being directed to the center of

the puddle. This concentrates heat on one side of

the joint and results in poor fusion on the neglect-

ed side. It also can create more buildup on one

side of the joint than the other.

Correction: Hold the gun so that the angle of the

neck stands perpendicular from side to side.

Correct Technique: The gun is held in a near

vertical position. A variance of 5 degrees or less

is acceptable from side to side. The purpose is to

prevent the arc from being concentrated on one

side of the weld joint or the other. This balances

the heat on both sides of the joint and keeps the

bead centered. Don’t confuse this with push or

pull angle in the travel direction.

Correct Technique: The gun is angled toward the

back of the weld when traveling forward. This

angle should not exceed 15 degrees. This pro-

vides a narrower but more deeply penetrating

weld. Use this method when Flux Core wire is

being used. Use this method where the unit may

be reaching its maximum welding capacity. Not for

use with Aluminum wire.

Correct Technique: The gun can be angled toward

the front of the weld when traveling forward. This

angle should not exceed 15 degrees. This pro-

vides a wider and generally more pleasing weld.

However it is shallower penetrating. This method

typically allows a much better view of the arc. Use

for most types of welding unless deeper penetra-

tion must be achieved.
