Step by Step Instructions

1 Set up your welder and workspace
2 Practice with scrap metal
3 Tack weld your metal pieces in place
4 Weld the two pieces together
  • Step 1. Set up your welder and workspace

    Always read the manufacturers instructions for the welder before starting. The earth lead clamps to the steel you are welding. The Torch Lead is where the wire feed comes out. On the front there are dials for the wire feed speed and an adjustable power setting.  

  • Step 2. Practice with scrap metal

    Use some scrap metal to check the wire speed control is right and power levels are correct for the sort of material you are going to weld. 

  • Step 3. Tack weld your metal pieces in place

    Attach the earth clamp to one of the pieces of metal you are welding. Check your Torch Lead is nice and straight, and make sure your material is clean and free of rust and paint. Put a couple of tack welds at each end to hold your metal pieces together and make sure they are in the right position. Use a wire brush to clean up the join. 

  • Step 4. Weld the two pieces together

    Once you are happy with the position of your metal pieces weld them together. Run a weld line down each side of the join. Clean the area with a wire brush to remove any residue. Finish with rust protector or undercoat to protect the area.
