@ oldeshooter - we also run a Lincoln 210MP, mainly for MIG process with .030 wire with C25 shielding gas, and for training humans with DC TIG. Excellent machine.
Recommendations:
* Integrate a 12” x 24” x 1/4” Aluminum plate to your welding table for all Stainless Steel work. Connect work lead directly to the plate, if direct-connect to the work piece is impractical. ~ $45 in material cost.
* Integrate a 12” x 24” x 1/4” Stainless Steel plate to your welding table for all Aluminum work. Same work lead and direct-connection protocol as described above. ~ $100 in matl cost.
Obtaining a solid ground is critical for all welding, especially with GMAW-S (ie. MIG - short circuit transfer). And, materials to be welded need to be clean:clean. Surface contaminates removed and devoid of all mill scale. Tip: if primarily building with 3/16” thick and less, source CRS (cold rolled steel) over HRS (hot rolled steel) from your local steel supplier. The co$t delta between the two material classes from our local supplier amounts to approx 10% greater for CRS.
Note: the above material combinations are grounded in metallurgy. That is, selected based on the “delta” between their heat of thermal conductivities which aids in injected heat (going into the work piece) and joint fusion.
General welding questions that dont fit in TIG, MIG, Stick, or Certification etc.
