Welding Guidelines (Continued)

aluminum welding

Any aluminum surface to be welded, must be cleaned
thoroughly with a stainless steel brush to eliminate any oxidation
on the weld and grounding surface. 100% Argon shielding gas
must be used when welding aluminum. If 100% Argon is not
used, metal penetration is unlikely. A PTFE wire liner, smooth-
groove drive roller and aluminum contact tips are recommended
when welding aluminum. Campbell Hausfeld offers these parts
in Kit WT2531. Call 1-800-746-5641 to order.

The type and thickness of the work piece dictates which way to
point the torch nozzle. For thin materials (18 gauge and smaller)
and all aluminum, the nozzle should point out in front of the weld
puddle and push the puddle across the workpiece. For thicker
steel, the nozzle should point into the puddle to increase weld
penetration. This is called backhand or pull technique (See
Figure 12).
