How to hold a MIG welding gun?

The safety of an operator depends on the level of comfort with using welding equipment. Apart from PPE, ergonomics has a vital role in maintaining the operator safety. A task that a welding operator needs to complete should be free from repetitive reach, twist, grip, or move. These minor problems, when ignored, may lead to stress and injuries.

MIG gun can be operated with one hand. The use of both hands makes welding more comfortable and accurate. One hand operates the gun while the other guides and angles the torch for stable function.

Keep the hands at elbow height or slightly below. The work should be placed between the waist and shoulders of the operator to minimize posture stress. Hold the torch with one hand and support the neck with the other hand to make a nice straight bead. You can use your left hand as a pivot, for the other hand, when making a bead.

How to choose the best MIG welding gun? – Buying Guide

Cooling options: Air Versus Water:

Amperage requirement, cost, and operator's preference determine the selected cooling mechanism. In water-cooled guns a radiator holds the water for cooling and sends it into the gun, hot water is then returned to the radiator and sent back after cooling.

An air-cooled torch using argon based gas cools 40 – 50% slower than the water-cooled one. This torch rating is further 20 – 30% reduced during pulse welding.

Air cooling procedure is suitable for guns that run on lower amperage for a limited period. The ambient air and shielding gas are a means to cool these guns.

Water-cooled guns are more expensive and have a much higher maintenance cost. They require more equipment and are difficult to move around. Water cooling is usually preferred for guns working at higher than 300 Amp, and require long, continuous welds.

Required Gun Amperage:

The appropriate amperage must be considered before selecting the MIG gun. You should remember that higher amperage than required is not always right. It increases unnecessary operator fatigue and machine downtime.

Small amperage guns are lightweight, flexible, and cheap. They are easy to use and do not cause discomfort to the operator. However, for long continuous welds and thicker materials, guns with high amperage are required.

Fume Extraction Guns:

The Occupational Safety and Health Administration (OSHA) and similar regulatory institutes had developed some regulations regarding the maximum exposure limits for welding fumes and toxic particles. This lead to the evolution of fume extraction equipment. Companies that prioritize the health and safety of weld operators are interested in investing in such equipment.

These guns are available in various amperages, handle designs, and cable styles. These guns help maintain a clean and comfortable welding environment in your shop or company.

The fume extraction guns absorb the fumes generated during a welding process. These guns work by the material’s movement. Its vacuum chamber pumps the vapors through the handle into a hose that includes both the base metal and the filler material.

Torch Neck: Flexible or Fixed:

Flexible necks are a better option for projects which require tight access joints. It gives complete access to tight, confined areas. Adjustable swan necks can reach any area where you point it.

Fixed necks are better where the weld points are easy to access without bending the gun. In this case, it provides better operator control over the gun head, resulting in smooth welds.

Quick Gas Diffuses

The shielding gases used for MIG welding include carbon dioxide, oxygen, helium, and argon. They have their specific roles and therefore selected carefully according to the welding process, cost, preparation requirements, base material, and required weld finish properties.

The gas should be following the wire used in the welder. A clogged diffuser or a narrow nozzle may cause blockage in gas diffusion and result in spatter and porosity. Spatter resistant consumables like those with built-in spatter guard allow double diffusion of shielding gases.

Replaceable and Easy Maintenance Whips:

Consumables play a vital role in saving your welding costs. High-quality consumables reduce the need to change the tips and minimize equipment costs and operator downtime.

The nozzle, diffuser, and contact tips are consumables. Consumables impact the quality of welds and welder's productivity. Therefore, you should select and maintain it carefully.

The MIG gun liner provides unobstructed passage for the wire to travel through the cable and gun into the nozzle. A defective one can produce weld defects and lessen weld productivity.

Maintenance-friendly MIG guns are convenient, reliable, and less time-consuming. These factors ultimately reduce the total cost of a welding operation.

Lockout and dual Schedule Triggers:

Dual schedule triggers or the lockout trigger are the most common options operators look for. They can be available as an auxiliary button or an integrated double pull switch.

The main benefit of this function is that it enables the welder to operate electrically. The operator needs to pull the trigger once and lock it. Then he can just run the welding gun’s front end through the metal to achieve a clean weld. Upon another stroke, the gun will stop feeding the wire.

This feature reduces fatigue and strain when you need to perform long welds. It also maintains the operator's focus on feeding the wire.

Long Enough C Handle

MIG gun handles come in vented styles in both straight and curved handles. The operator who prefers the trigger on top usually selects straight handle. Curved handles do not offer this feature. A straight handle allows you to place the trigger on top or bottom by rotating the neck.

Conclusion

It is better to choose the MIG gun according to the requirements of your welding projects. A well-chosen MIG gun gives optimum performance without premature failures and unscheduled downtime. It also saves time and money required for repair and replacement. The best MIG welding gun will ultimately reduce the total cost of welding.
