Feedback from a welder:

Great device! 8 out of 10. I bought this semi-automatic 5 years ago, I cooked a lot and often, I didn’t regret it. We had to do everything. And he cooked the gates, and he cooked the bodies. Everything is working as it should. At the same time, sometimes I did not have the wire of the required diameter, and I used a thin one, plus I reinforced the structure with a channel. In the end, everything is fine, no complaints. I am very pleased with the device; in all the years of use there have been no problems. The only negative: sometimes the button on the sleeve gets stuck, but this is not critical after five years of use.

How to treat the body after welding

After completing the repair, it is necessary to clean the welding seams from slag, since the metal underneath quickly oxidizes. In areas hidden from view, a metal brush is sufficient. In open areas, the body is processed after welding using a grinder with a grinding wheel or a flap attachment. To clean hard-to-reach seams, use a grinding machine with a burr.

Cleaned surfaces are degreased with acetone or gasoline, then treated with an anti-corrosion compound or acid primer. Epoxy putty is used to protect against corrosion. Thanks to its dense structure, it reliably protects the metal surface from contact with moisture and air and is used as a leveling layer.

After applying a thin first layer, it is left to dry for a day. You cannot use a hairdryer to speed it up, because after the top layer dries, the putty inside will remain damp, since the moisture has nowhere to evaporate. Scores are then applied to roughen the surface using 120-grit sandpaper. After applying 2 - 3 layers, preparations for painting are made.

Automotive seam sealant is used to protect seams that are invisible from the outside in easily accessible areas. If necessary, it is smoothed with a spatula and painted. The sealant is applied to hard-to-reach places using a pneumatic sprayer through a plastic tube.

SVAROG REAL MIG 200

Russian semi-automatic welding machines are also worthy of the attention of welders. In this rating, we decided to talk about one excellent model from Svarog - REAL MIG 200. This is a well-known and popular device that has long established itself as a good option for a summer house and workshop.

With this machine you can easily weld aluminum and stainless steel, carry out MMA and MIG/MAG welding. The built-in wire feeder is reliable and easy to use. It can be used to run wire. The arc burns stably even with significant voltage drops.

You can set the welding current up to 200 Amps, which is enough even for a small workshop. The penetrations are deep, there are no defects. The device operates very stably and is not afraid of voltage surges.

Why do you need semi-automatic welding if there is an automatic machine?

Despite the technology and similar name, the devices have obvious differences. When using an automatic machine, the user only needs to set the functions, that is, configure the device, and the machine itself will do the necessary work. With semi-automatic welding, the user does the work himself and also sets up the machine. In automatic mode, the semi-automatic machine only feeds welding wire.

Many users wonder why use semi-automatic welding if it is more convenient to use an automatic welding machine. The choice of welding depends on the conditions and scale of the job. Semi-automatic welding is mainly used, this is due to the fact that many people use the tool for small jobs. Automatic machines are needed only for professional purposes for large continuous work. In addition, automatic equipment is expensive and requires special knowledge to configure. The welding process is the same for both types, the only differences are in user participation, functionality, power and cost.

The principle of working with equipment

A semi-automatic device that can be used in a garage consists of the following elements:

transformer;
mechanism for feeding wire;
welding sleeve;
burner with wire;
nozzle or conductive tip;
inert gas supply system.

The operating principle of such equipment comes down to the following: a current is constantly supplied to the wire, which heats and melts the metal in a limited area. At the same time, an inert gas enters the treated area, which prevents oxidation of the metal, which improves the quality of the final weld.

These devices are called semi-automatic because the electrodes are supplied automatically, and a person is directly involved in welding the material.

Before starting work, one clamp is attached to the metal, and the second is attached to the sliding tip of the torch. The polarity and current strength are set depending on the type of metal being processed.
