It can typically run Gas (with solid wire) or Gasless (with flux-core wire) by reversing the polarity.

The CEM Dual MIG 120 is a lightweight, entry-level dual-voltage MIG welder marketed for hobbyists, DIYers, and light workshop tasks. It supports MIG welding (with flux-cored wire), typically offers adjustable voltage/wire feed settings, and often includes basic accessories (torch, ground clamp, spool, regulator/flowmeter for gas models). It’s intended for thin-gauge steel, mild steel fabrication, auto body patching, and general home repairs.

However, a welder is only as good as its setup. In this guide, we will break down the crucial steps from the manual to get you welding efficiently, covering both MIG (gas) and flux-cored (gasless) setups. 1. Safety First (Important)

If the wire "stutters," the liner inside the torch lead is likely dirty. These can be replaced with universal steel or Teflon liners. 5. Where to Download a Manual

The manual emphasizes changing polarity based on wire type:

60A to 120A, suitable for thin to medium-gauge steel (typically 1–5 mm). Wire Compatibility:
