Campbell Hausfeld WG3013 - Manual (Page 9)

ALUMINUM WELDING
Any aluminum surface to be welded,
must be cleaned thoroughly with a
stainless steel brush to eliminate any
oxides on the weld and grounding
surface. 100% Argon must be used
when welding aluminum. If Argon is not
used, metal penetration is unlikely.

PUSH VS PULL TECHNIQUE
The type and thickness of the work
piece dictates which way to point the
gun nozzle. For thin materials (18 gauge
and up) 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 14).
1. Verify that welder is OFF and power
cord disconnected.
2. Remove welder cover to expose the
ON/OFF switch.
3. Disconnect the black and white
power cord wires connected to the
ON/OFF switch.
4. Disconnect the green power cord
wire connected to welder frame.
5. Loosen the cord strain screw(s) and
pull cord out of strain relief.
6. Install new cord in reverse order.
