Industries from different segments can increase productivity with semi-automatic mig welding equipment. This procedure is carried out with the help of specific machines, which make the activities of welders more practical, efficient and reliable.
One of the main advantages of semi-automatic MIG welding equipment or also known as the GMAW process is the ease of welding in positions that are difficult to access, such as high places or very close to the ground. In general, GMAW or Semi-automatic MIG welding is practiced to make seams in any type of joint or position. In illustration A you can see the different positions and types of joints that can be made with the Semi-Automatic MIG welding equipment.
It is worth noting that MIG welding is ideal for surfaces made of carbon steel, stainless steel, aluminum or silicon bronze.
The automated procedure helps in the joining of beams or plates of different calibers and is one of the best solutions to perform production welding rather than maintenance.

Being fed by a continuous 15 kilogram coil of wire, the production capacity becomes much higher than other processes that require more breaks for replenishment. For example, the one that uses coated electrodes, whose average length is 350 millimeters, or the TIG methods, which are manufactured with 1 meter rods.
2. Welding can be done in any position.
3. Deposition rates are higher compared to stick or TIG welding
4. The welding speed is higher, bringing higher productivity.
5. It does not require post-weld finishing, since it does not generate slag.
6. Minimal losses.
Unlike the stick electrode and TIG process, in which the tips of the electrodes are lost, the utilization is total, without wasting material.
7. Efficiency in welding execution time.
8. Great value for money.

Case of success with semi-automatic Mig welding in aluminum
One of our customers bought a roll of aluminum welding wire and a week later called back for warranty because the wire got stuck.
The client was visited and we noticed that he was using a conventional gun for the carbon steel MIG process to apply the aluminum wire, this in itself generates problems in the feeding of the wire, since aluminum is a very malleable material. In illustration B you can see what the weld looked like using a conventional gun.
To weld aluminum, a push-pull type gun is needed, which is mentioned in this success story and which uses a synchronous feeding system with the same speed between the rollers of the main feeder and micro-rollers in the gun itself.
On that occasion, we offered the client a demonstration with the Millermatic 350P Miller brand Pulsed MIG welding machine, which is one of the best alternatives for aluminum welding when used in conjunction with the push-pull gun. The machine was demoed and the customer noted that the wire they had requested warranty for worked perfectly with this push-pull machine and gun solution.
Subsequently, as the welds of this client were long, it was recommended to use a linear welding tractor to be able to make more presentable weld seams and with better penetration throughout the sheet, with which the client decided to purchase the Steelmax IL RUNNER model.
When testing the tractor, we realized that it was very difficult for the operator to remotely start and stop the cart, so we also developed a remote control so that the operator could remotely start and stop the tractor.
It is important to note that the manufacturer of the welding cart does not have this control, but with the knowledge and experience of our technical team, we developed the remote control and the customer was completely satisfied with its application.
