![]() When it comes to preparing your welding machine and welding gun, there are a few things to consider depending on what type of metal you’re working on. That means grinding or sanding away any surface gunk, rust and paint just like the weld area. Make sure the ground clamp has an excellent connection to bare metal or you won’t get a good arc. Things light on fire quickly from red hot metal!)įinally, securely attach the ground clamp to your welding table (if it’s metal), or the larger piece of base metal you’re welding to. That includes rags, fuel, oil, wood…even your lunch bag! (IMPORTANT: It’s always critical to have an ABC class fire extinguisher within reach when welding. Clear your welding table and the ground around where you’re welding of any dust, metal scrap and shavings. Next, prepare the workplace around your welding area. Preparing the metal is essential if you want a strong joint between the pieces! Use an angle grinder with a flap sander wheel, wire brush or paint and rust stripping disk.

The cheapo handheld shield that comes with many flux-cored MIG welders is useless and doesn’t offer the protection needed for your skin or eyes. You must use a welding helmet with a full-face auto-darkening shield because flux core welders throw off a lot of spatter and UV light. No matter what you’re welding or how you’re doing it, taking safety precautions with the right personal protective equipment (PPE) comes first.
