A: We provide 1 year warranty time for the whole machine since you received it.
During the time, we will supply you the free spare parts for maintanence.
Meanwhile, we offer on-line technical supports for operating guide and troubleshooting.
4. Q: Can I use my ALPHA welder on the generator ?
A: Yes, we can.
While the welder may operate OK on lower output etc - the fact remains that using an underpowered generator does increase the risk of damage to the welder.
A: We accept T/T, LC, O/A and others.
6. Q: What is Hot Start, Arc Force & Anti-Stick?
A: What is Hot Start ?
Hot Start is a special feature for MMA (stick-electrode) welding where the machine delivers a peak of current when striking the arc. This is important as it significantly increases the ease of starting electrodes, especially in difficult conditions such as damp electrodes, imperfect job surface, or when using 'difficult to run' electrodes, etc.
What is Arc Force ?
Arc Force, sometimes called "Dig" or "Arc Control", is a similar feature to Hot Start, except Arc Force operates during welding, not just at ignition. When the welding machine senses a short circuit it will deliver a peak of current. This greatly assists in stabilizing the arc, preventing the arc from cutting out while welding and preventing electrode sticking.
What is Anti-Stick ?
Anti-Stick allows the stick welding electrode to be easily detached, if it does begin to stick to the job. When the machine senses that the electrode is sticking, it will collapse the welding current to stop the electrode from continuing to weld itself to the job, allowing it to break free easily.
