MIGWELD 250 MP
• Fillet Welds
The leg of your weld should be equal to the thickness of the materials you
welded.
• Aluminum MIG Welding Tips
• It is highly recommended to use a spool gun when welding with aluminum.
However, if you don’t have access to one, you can try using an extremely short
gun.
• Keep your gun straight.
• Use Argon as your shielding gas
• Push gun away from you as you weld (Push gun technique)
• Feeder Problems? A possible solution to feeder problems is using a contact tip
that is one size larger than your wire.
• ER403 wire can be used for most projects. ER4356 should be used when your
weld needs to be stronger, or rigid.
• Always clean your aluminum before welding, using a stainless steel wire brush.
This brush should only ever be used for cleaning aluminum wire to prevent
contamination.
