Stick Welders come in two basic types, Transformer or Inverter. Transformer Stick Welders Whilst not always the case, the vast majority of Transformer Stick Welders have a moving shunt Transformer, meaning you wind a big knob on the front of the machine to adjust power output. The advantage of a Transformer is they’re cheap. Sadly, […]

I get asked “how many welding rods are in a box”, a lot! So I guessed it was about time I published some figures! There are some variables when it comes to how many welding rods are in a box. The length of the welding rod is the biggest variable. Smaller diameter welding rods, eg […]

How Many Amps for Stick Welding, like a lot of things in Welding, is not a precise science because it depends on a number of variables: So for example, a Butt Weld in 10mm Steel, with a ‘V’ Prep where a Root run is applied, followed by a Fill and Cap run, will need less […]

Welding Cast Iron has quite a few potential pitfalls, but if done correctly, it’s not difficult. Why is Welding Cast Iron problematic The key reason why welding cast iron can be problematic is the high carbon content.  During the welding process, this carbon migrates into the weld metal and/or the heat affected zone adjacent to […]

For most things in Life, preparation is important, Weld Preparation is no exception. There are some fairly obvious weld preparations Where thicker metals are to be welded, a joint preparation may be needed. Butt Weld Preparation Typically, this would involve creating a ‘V’ preparation by grinding a chamfer onto each piece of the joint. A […]
