Hints and Tips for Using GYS PROTIG 201 Flexible Voltage AC/DC TIG Welder
Take Time to Get Familiar with the Controls
The PROTIG 201 offers a wide range of settings, and exploring them at a relaxed pace can help you find combinations that work well for your style. Even small adjustments can gently improve arc comfort and weld appearance.
Choose the Right Tungsten for the Job
Using a suitable tungsten type and diameter can make the arc feel smoother and easier to guide. For example, many users find that using a dedicated tungsten for AC aluminium and another for DC steels keeps results more consistent.
Let the Machine Warm Up with You
Allowing a short warm-up period can help the welder stabilise, especially if the workshop temperature changes often. This can support a steadier arc as you begin your first weld of the day.
Make Use of the Flexible Voltage Feature
The flexible voltage capability can offer more convenience when moving between locations. Trying the machine on both 110V and 230V, where suitable, may help you understand how each supply affects arc behaviour.
Experiment with AC Balance on Aluminium
Adjusting the AC balance can gently influence cleaning action and penetration. Small tweaks can help you find a setting that feels smoother and produces cleaner results on different aluminium thicknesses.
Try Pulse Mode for Added Control
Pulse settings can help when you’re seeking a steadier bead or working on thinner material. Starting with lower pulse frequencies may make the rhythm easier to follow as you get used to it.
Develop a Comfortable Torch Angle
Keeping the torch at a relaxed, consistent angle can support better gas coverage and minimise turbulence. Many users find that a slightly lowered hand rest or support point can ease longer welds.
Check Gas Flow and Cup Size
A suitable gas flow and cup size help maintain good shielding around the weld pool. If you notice occasional porosity, adjusting the flow slightly or trying a different cup size may gently improve results.
Use Clean, Well-Prepared Materials
Even a brief clean of the joint area can make welding feel smoother and more predictable. Removing light oils, dust, or oxidation helps the arc behave more consistently.
Take Breaks to Maintain Comfort
Short breaks can help reduce fatigue, making torch control easier and welds more consistent. A steady, relaxed hand tends to make a noticeable difference in bead appearance.
