Copperjet - high speed copper coating unit for CO2 welding wire using our own product the world famous Inhibitor E1 Pickling - single and multi strand acid pickling lines using hydrochloric- or sulfuric acid in line with hot dip galvanizing, phosphating and electroplating
Volts are volts, inductance is inductance, wire diameter is wire diameter, and wire speed is wire speed. My 22 year old MM200 doesn''t have anything regarding argon mixes on the inside cover chart or OM - all reference literature refers to use with straight CO2.
It was possible to reach high welding speed in the root pass, 50 cm/min in a keyhole mode. The wire dynamic movement contributed to reach great process stability and robustness for all joint passes, from root to finishing. The macrographs and x-ray analysis
As mentioned earlier, test welding while you’re still new is very important, in particular, when you are using a MIG welder, getting the right wire speed / voltage / amp settings can …
Carbon Dioxide (CO2) is the most common of the reactive gases used in MIG welding and the only one that can be used in its pure form without the addition of an inert gas. CO2 is also the least expensive of the common shielding gases, making an attractive choice when material costs are the main priority.

Wire Diameter The wire feed speed for aluminium welding is about twice that of steel welding with the equivalent diameter wire. That means you can use a thicker wire for aluminium. A thicker wire will be less prone to s nesting. Use 1.0mm diameter
Metal Inert Gas (MIG) welding was first patented in the USA in 1949 for welding aluminium. The arc and weld pool formed using a bare wire electrode was protected by helium gas, readily available at that time. From about 1952, the process became popular in the
Mild Steel welding – “SpeedShield 5/2” – An Argon/CO2/Oxygen mix suited for MIG welding. SpeedGas can also do other mixes for specialty jobs. SpeedGas are able to sell cylinders outright. It makes sense for most clients to own their cylinder rather than pay
The speed of welding will affect the weld appearance and penetration. Decreasing the speed of torch travel will increase penetration. The weave pattern of the torch also influences weld penetration. Preparing the joint in to a "V" shape or leaving a
Direct current is used for MIG/MAG welding. The arc burns between the workpiece and a consumable wire electrode, which is also the source of the necessary filler material and is essentially endless. It is supplied either on a spool or in a drum and is guided to the

This is Mig Welding Basics part 2. In part 1, we left off trying different wire speed settings and saw and heard the difference it made in the arc and puddle. Also in part 1, I asked for comments to make sure I cover things I might otherwise omit or gloss over.

In other words, unless you do something to help the bead lay down flat, it will hump up. this is partly due to gravity but is also just a characteristic of short circuit mig welding. I either use an upside down V technique or a series of triangles to make the metal spread
Wire speed needs to be reduced or arc becomes instable. Actually, the 100% CO2 tests should be done again with higher torch speed; the results would probably be better. 75% Argon, 25% CO2 …
