SP-5.3 3-Phase Smart Double Pulse MIG Welder

The new Pro Spot SP-5.3 SMART Double Pulse MIG welder, is a 3-phase welder with microprocessor controls. It provides excellent welding performance on any materials and any thickness, regardless of weld time.


Component List

Auto Switching

Simply pick up the appropriate torch for the base metal you want to weld and pull the trigger. The SP-5.3 will automatically switch the weld program and synergic curve — no need to change wire spools or shielding gas.

MIG Welding

MIG Welds

Preprogrammed synergic curves maintain optimal arc stability and weld quality.

With three wire spools dedicated to three separate torches, the SP-5.3 is capable of easily switching between Steel, Aluminum and Silicon Bronze welding materials. This gives the operator seemless transitions fromm material to material and increased work flow which leads to a faster cycle time.
