Using your Lincoln Front-Mounted AC/DC 225/125 Arc Welder is a breeze. First, make sure it's properly installed. It comes with an attached input power cable and plug, so just connect it to a suitable power source.
To start welding, use the front-mounted AC/DC polarity switch and the full-range amperage selector switch to set the right parameters according to the electrode you're using. The electrode selection chart on the machine case can be a big help here.
For a stable arc, especially when using certain electrodes, select the DC welding arc with the electrode polarity switch on the front. If you're working on heavier plates and need higher deposition rates and travel speeds, choose the AC welding arc.
When you're done, store the welder in a dry place. Its compact size makes it easy to put away. The fan-cooling feature helps protect it from overheating, but it's still a good idea to let it cool down completely after use.
Keep an eye on the vermin-resistant mesh bottom. Make sure it's clean and in good condition to keep rodents and pests out. Also, the powder paint finish gives it high corrosion resistance, but avoid exposing it to excessive moisture.
Remember, this welder is UL listed and CSA approved, but always follow safety guidelines. And it comes with a 3-year warranty on parts and labor, so if you run into any issues, you're covered.
