Can the old test welding machine be converted into a gas-powered welding machine?

Strongly do not recommend to modify;

First of all, from a professional point of view:

The majority of the output of the two shielded welding is the flat characteristic;? And most of the gas-shielded welding machine (shielded welder) are DC output;?

And the traditional old-fashioned welding machine, the output is down characteristics, and mostly AC output;

So, the first thing to change is the output characteristics of the welding machine power supply, which requires professional knowledge;---- and, the traditional welding machine power supply is the use of the external characteristics of the transformer design to achieve the way, there is virtually no change in the possibility of;?

Two shielded welding need wire feeder, of course, can be equipped with external split wire shut-off machine ------ this is still a small problem;

Two shielded welding gas decompression is the need to do the heating process, because of carbon dioxide gas decompression, there will be a heat-absorbing reaction; do not heat up will be a big deal;

And involved in a very professional thing is: gas-shielded welding welding process droplet transition is more violent;? The transition is more violent;? Then the dynamic response of the welding machine is more demanding;?

So, it is not recommended to change it for non-professionals, not to mention to change a traditional AC hand-arc welding machine to a DME welding machine.
