Weld Aluminium With a Spoolgun
MIG welding uses a non-stop spool of wire to dream up a weld bead on metal. The soft description of aluminium wire causes a MIG welder to preserve when the wire travels down the margin of the MIG welder to the MIG gun. To divide the distance the aluminum wire has to expedition, you devoir to appropriateness a spool gun. A spool gun is a self-contained MIG welder that holds a immature one pound spool of aluminum wire in the gun, rather than remotely in a MIG welder.
Instructions
1. Assign the two pieces of scrap aluminium Apartment lodgings on top of the welding table.
2. Levy on your safety glasses, welding gloves and face shield.
3. Attach the 4 inch flapper wheel to the 4 inch angle grinder and lower your face shield.
4. Slide one piece of aluminum until one side of the aluminum overhangs the welding table by 2 inches and lower your face shield.
5. Hold the scrap piece of aluminum firmly to the welding table with one hand and pull the trigger of the 4 inch angle grinder to place a 15 degree bevel on the edge of the piece of aluminum. Repeat the process to bevel one side of the other piece of aluminum.
6. Remove your face shield, put on your welding hood and slide the two beveled sides of the aluminum pieces together.
7. Turn on the welding machine and set the voltage and wire speed of the spool gun as specified by the welding chart attached to the welding machine.
8. Align the wire protruding from the tip of the spool gun with the weld joint created when you slid the beveled sides of the aluminum sheet together and lower your welding hood.
9. Pull and hold the trigger of the spool gun for 2 seconds to place a tack weld on the weld joint. Moving the weld puddle 1/4 inch will eliminate heat building up and blowing through the soft aluminum as you weld.12. Allow the weld joint to cool for 30 minutes before handling to avoid becoming severely burned.
11. Push the weld puddle 1/4 inch and hold for 1 second. Repeat the movement along the weld joint to weld the aluminum with the spool gun. Repeat the process to place a tack weld every 2 inches along the weld joint.10. Move the tip of the spool gun to one end of the weld joint and pull the trigger of the spool gun to start welding the weld joint.
