Multi-process welders make it easy for welding operators to tackle a variety of fabrication or construction jobs and projects on the jobsite, in the shop or in the field without switching power sources – saving you time and money. These welders are capable of performing MIG, Stick, TIG, and Flux-Cored welding processes ( if not all, then a combination of a few of these processes). Find the one that’s right for your application

The best multi-process welding machine can usually handle two or three kinds of welding with optimum efficiency, if you are interested in switching between MIG, TIG, and stick welding, all within minutes, with the same machine, then multi-purpose welding machines are an incredible option for the modern workshop or hobbyist who wants some measure of diversity at a low cost.

Making perfect choices won’t be an easy task for our customers, hence here is an extensive research revealing the best multi-process welding machines in Nigeria and hopefully you will find this article useful toward making informed decisions in your procurement. We hope you enjoy our reviews and guide.

These welders perform the best over all the other multi-process welders , in the widest range of materials. This review captures but a few on the list.

2. PowerFlex welding machine MMA-500i 3 phase electric-powered

The powerFlex welding machine MMA-500i 3 phase (electric-powered) can be used in Manual Metal Arc (MMA) also known as Shielded metal arc welding (SMAW), also flux shielded arc welding also known as stick welding is the most flexible and one of the most widely used arc welding processes. It involves striking an arc between a covered metal electrode and a workpiece.

The heat of the arc melts the parent metal and the electrode which mix together to form, on cooling, a continuous solid mass. The central metal electrode or core wire acts as a consumable, providing the filler metal for the weld. MMA welding can be used to join most steels, stainless steels, cast irons and many non-ferrous materials. For many mild and high-strength carbon steels, it is the preferred joining method. Due to the industrial processes in Nigeria this welding machine is in great demand.
